Part Number:AM3354

Dear Sir，

When transplanting wm8960 sound card on AM335x there's some trouble. Urgently need the master's advice to help me to solve the problem.
Question as below:
Now the situation is that when playing audio files through aplay, it is jammed. The oscilloscope measures mcasp0_aclkx, mcasp0_fsx, mcasp0_axr0/mcasp0_axr1 without signal output. It can not automatically exit after tracing to mcasp_start_tx. It can response when click Enter and can exit through Ctrl + C. No audio output.
Thank you so much and looking forward the relpy.
Have a nice day!

kernel version:4.1.18  let wm8960 for slave。

dts configuration is as follows：

mcasp0_pins_default: mcasp0_pins_default { 
pinctrl-single,pins = < 
0x190 (PIN_OUTPUT_PULLDOWN | MUX_MODE0) /* mcasp0_aclkx */

0x198 (PIN_INPUT_PULLDOWN | MUX_MODE0) /* mcasp0_axr0 */ 
0x1A8 (PIN_OUTPUT_PULLDOWN | MUX_MODE0) /* mcasp0_axr1 */ 
>; 
};
mcasp0_pins_sleep: mcasp0_pins_sleep { 
pinctrl-single,pins = < 
0x190 (PIN_INPUT_PULLDOWN | MUX_MODE7) /* mcasp0_aclkx */

Hello,

I want display two different frames at a time using dmaswms link.

I observed that, dmaswms link crops the frame as per given parameter and then displays cropped frame.

But I want to display a resized frame.

So, does dmaSwMs link supports resizing and then display frame?

Currently parameters are set as,

    Alg_swmsPrmObj->maxOutBufWidth  = 1920;
    Alg_swmsPrmObj->maxOutBufHeight = 1080;
    Alg_swmsPrmObj->numOutBuf        = 5;
    Alg_swmsPrmObj->useLocalEdma    = FALSE;
   
    Alg_swmsPrmObj->initLayoutParams.numWin            = 1;
    Alg_swmsPrmObj->initLayoutParams.outBufHeight    = 1920;
    Alg_swmsPrmObj->initLayoutParams.outBufWidth    = 1080;
    Alg_swmsPrmObj->initLayoutParams.winInfo[0].chId     = 0;
    Alg_swmsPrmObj->initLayoutParams.winInfo[0].height    = 500;
    Alg_swmsPrmObj->initLayoutParams.winInfo[0].width    = 500;
    Alg_swmsPrmObj->initLayoutParams.winInfo[0].inStartX    = 0;
    Alg_swmsPrmObj->initLayoutParams.winInfo[0].inStartY    = 0;
    Alg_swmsPrmObj->initLayoutParams.winInfo[0].outStartX    =100;
    Alg_swmsPrmObj->initLayoutParams.winInfo[0].outStartY    =100;

Hello Team,

We use custom h/w and software based on DRA746 and PSDK 3.03

Currently we are facing one issue specific to video playback for following use case:

1. Start the video playback through HMI.
2. Press next/previous continuously 8-10 time.

We observed that video screen goes blank, but video pipe line is in play state and we are able to hear the video sound. If we press next/previous again we are able to hear the audio of next video, but video is not coming on the screen.

We checked the video surface it exists, but not attached to layer and surface properties are not set.

And we are not getting the surface creation and surface destruction events when we are pressing next/previous when issue occurs.

Do you have any inputs for this issue?

In community I found one issue in waylandsink related to race condition on multi-threaded client https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/merge_requests/74/diffs?commit_id=f7f21f2b847ce1ba0c6d476577b7ed252e113db7. Provide your inputs for this as well.

Tool/software: TI-RTOS

Hi,

We have developed a MCAN module on Vision SDK 03.03.00.00. We are able to transmit and receive the CAN FD frames by connecting two TDA2P-EVMs.

We have a customized TDA2P board, on this the MCAN module is able to transmit classic CAN frames by setting the FDF bit to 0, DLC to 8 and copying data buffer of 8 bytes in the MCAN TX message structure to PCAN device. (using PCAN-View tool on PC)  We are also able to receive frames sent from the PCAN device ( classic CAN frames with standard id ).

When we try to transmit CAN FD frame by setting the FDF as 1, DLC as 64 and copying data buffer of 64 bytes, no messages are received on the PCAN device. If we try to transmit CAN FD frame from the PCAN device, we do not receive any frame.

Note:

1] Nominal bit rate is set to 1 Mbps and data phase rate to 5 mbps ( as suggested in the sample application of MCAN in the csl examples).

2] CAN FD frames with standard id can be sent and received on EVM with same MCAN module.(connecting 2 EVMs)

3] Standard ID frames are transmitted from PCAN device.

4] FD operation enable bit is set to enable FD operation while we init the MCAN. (even when we transmit and receive classic CAN frames)

Please let me know what is the issue ?

Thanks and Regards,

Part Number:AM4378

Tool/software: Linux

Dear TI  Team,

We are currently using the AM4378 with a MYIR Rico(Please visit the site to view this file)Board and an ATWILC1000-MR110 wireless module ( https://www.microchip.com/wwwproducts/en/ATWILC1000  )mounted in a proto-board. In the past, we already used such Wi-FI module with other processors (IMX6/8 and Microchip… for example) without any problem and using the same kernel version (4.1.18).  Furthermore, also a Raspberry PI was used for a quick test and it did work smoothly….

However, with this processor, we are facing some issues.

Basically, we connected the WILC1000 in SDIO mode to MMC2 interface using the J11 connector on the RICO board (refer to http://www.myirtech.com/download/AM437x/RicoBoard_SCH_V10.pdf ). please note that since the SDIO pull-ups are not available on the Rico board, we added them externally (we used the same 10Kohm value used for the other mmc interface present in the Rico board)

The HW connections are the following:

MMC2_CLK         à A12

MMC2_CMD      à B12

MMC2_DAT0     à C5

MMC2_DAT1     à C6

MMC2_DAT2     à A4

MMC2_DAT3     à A3

CHIP EN is tied to VCC and the RESET pin is driven by GPIO5_8

The device tree is configured to reflect this in the following way:

&mmc3 {

                status = "okay";

                dmas = <&edma 30 0>,<&edma 31 0>;

                dma-names = "tx", "rx";

                vmmc-supply = <&dcdc4>;

                bus-width = <4>;

                pinctrl-names = "default", "sleep";

                pinctrl-0 = <&my_configuration_wifi_pin>;

                pinctrl-1 = <& my_configuration _wifi_pin_sleep>;

                //cap-power-off-card;

                //keep-power-in-suspend;

                ti,non-removable;

                max-frequency = <2000000>;

                ti,needs-special-hs-handling;

                ti,dual-volt;

                cap-sdio-irq;

                //disable-wp;

                #address-cells = <1>;

                #size-cells = <0>;

                wilc_sdio@2 {

                                compatible = "atmel,wilc_sdio";

                                reg = <2>;

                                gpio_reset = <&gpio5 8 GPIO_ACTIVE_LOW>;

                                //gpio_chip_en = <&gpio0 12 GPIO_ACTIVE_HIGH>;

                                //gpio_irq = <&gpio0 13 GPIO_ACTIVE_HIGH>;

                };

};

The IRQ line is commented since it is not actually used by WILC1000: when compiling the wilc1000 driver, we chose to use the in-bound interrupt of the SDIO interface;

The pins are defined as the following:

my_configuration _wifi_pin: my_configuration_wifi_pin {

                                pinctrl-single,pins = <

                                                0x44 (PIN_INPUT_PULLUP | MUX_MODE3) /* (C5)  gmpc_a1.mmc2_dat0 */

                                                0x48 (PIN_INPUT_PULLUP | MUX_MODE3) /* (C6)  gpmc_a2.mmc2_dat1 */

                                                0x4c (PIN_INPUT_PULLUP | MUX_MODE3) /* (A4)  gpmc_a3.mmc2_dat2 */

                                                0x78 (PIN_INPUT_PULLUP | MUX_MODE3) /* (A3)  gpmc_be1n.mmc2_dat3 */

                                                0x88 (PIN_INPUT_PULLUP | MUX_MODE3) /* (B12) gpmc_csn3.mmc2_cmd */ /* qspi_clk conflict */

                                                0x8c (PIN_INPUT_PULLUP | MUX_MODE3) /* (A12) gpmc_clk.mmc2_clk */

                                >;

                };

my_configuration _wifi_pin_sleep: my_configuration_wifi_pin_sleep {

                                pinctrl-single,pins = <

                                                0x44 (PIN_INPUT_PULLDOWN | MUX_MODE7) /* (C5)  gmpc_a1.mmc2_dat0 */ /* gpio1_17 */

                                                0x48 (PIN_INPUT_PULLDOWN | MUX_MODE7) /* (C6)  gpmc_a2.mmc2_dat1 */ /* gpio1_18 */

                                                0x4c (PIN_INPUT_PULLDOWN | MUX_MODE7) /* (A4)  gpmc_a3.mmc2_dat2 */ /* gpio1_19 */

                                                0x78 (PIN_INPUT_PULLDOWN | MUX_MODE7) /* (A3)  gpmc_be1n.mmc2_dat3 */ /* gpio1_28 */

                                                0x88 (PIN_INPUT_PULLDOWN | MUX_MODE7) /* (B12) gpmc_csn3.mmc2_cmd */ /* qspi_clk conflict */ /* gpio2_0 */

                                                0x8c (PIN_INPUT_PULLDOWN | MUX_MODE7) /* (A12) gpmc_clk.mmc2_clk */ /* gpio2_1 */

                                >;

                };

However, when we insert the module we get a lot of errors:

Attached you can also find the full dmesg content.

We cross-checked the hardware and it’s fine: we connected the our  WILC1000 prototype board to the Microchip ATSAMA5D44 EVK and it worked fine. Btw, the SAMA544 is running the same Kernel version of the Rico board. Given all the above, the only real difference is the SDIO driver and the device tree configuration: these are the only two things which are hw dependent.

Btw, we even lowered the SDIO speed for the TI (2Mhz), but using the SAMA544 with the same WILC1000 proto-board we could really work at almost at full speed even though the hardware was wired… so it’s not a problem of wires’ length.

Given that, we’d like to have your advices:

• Do you see any mistakes in the pin assignment of the SDIO interface?
• Atmel drivers requires to have in-bound interrupt: is the device tree well configured for this? Does it require to enable any option in the SDIO driver? Or is the cap-sdio-irq option in device tree enough?
• Since the hw set-up does not require a card detect, they suggest to add “non-removable”: I guess that the same can be done via ti,non-removable, right?
• Is the DMA properly configured? &mmc3 is the only mmc interface whose DMA’s configuration is not done on the am4372.dtsi file.

Thank you

Hi there,

For the purpose of connecting to a TDA2Eco, we have been using the Spectrum Digital XDS560v2 System Trace JTAG Emulator with Target Adapters.

This debugger is currently not available in any reseller in Europe and we would like to know which TI part is compatible.
It seems that the TMDSEMU560V2STM-U is compatible but I would like to be sure about it.
Can you please confirm the full compatibility between the Spectrum Digital XDS560v2 System Trace JTAG Emulator with Target Adapters and  TMDSEMU560V2STM-U for TDA2Eco usage?
Thanks for your time.

Hi ,

             We've design TI_AM3352's USB Port0 as client mode for our project , but it can't recognized by HOST PC(Windows)  .

             I've check the USB_ID , it's connect to MicroUSB directly . 

            And I've measure the voltage of USB0_VBUS is 5V when we plug USB Cable into Host PC side.

            =======================

            I've attach the log file :  "putty_20181222_1.log" , Do you have any suggestion ?

            I guess Host PC should be pop something in Windows Device Manager , right ?

I have spent some time trying to understand the details of the calibration done with the DDR3_slave_ratio_search_auto.out binary. There are just two things that I don't fully understand:

1) On our board the DATA_PHY_FIFO_WE_SLAVE_RATIO search finds a minimum value of 0 and a maximum value of about 0x154, resulting in a final value of 0xAA. Why is a minimum of 0 considered valid if the maximum is found to be more than one full clock cycle away? As far as I know any minimum less than the maximum minus tRPRE is wrong. In my case it still works because the average of minimum and maximum is less than tRPRE away from the maximum. But it is suboptimal since it is not centered within tRPRE.

2) The Ratio Seed spreadsheet calculates a seed value for DATA_PHY_FIFO_WE_SLAVE_RATIO that is twice as sensitive to the DQS length than to the CK length. Why? The FIFO WE slave ratio has to compensate for the time it takes the read command to travel from the CPU to the RAM chip and for the time it takes the result to travel back to the CPU. There is no second transfer on the DQ(S) lines starting after the result has arrived that has to be taken into account in the formula. The equivalent spreadsheet for Keystone I processors (SPRABL2) uses a different formula where DQS length and CK length have equal weight. Is the formula in the AM335x spreadsheet wrong?

Common targets are:    core-image-minimal    core-image-sato    meta-toolchain    meta-toolchain-sdk    adt-installer    meta-ide-supportdavid@david-desktop:~/tisdk2$ 

Part Number:AM3358

Dear TI Experts,

I have an FPGA attached to the GPMC bus of an AM3358 device and I am currently working on the FPGA side. To achieve maximum performance, the FPGA logic supports bursts of 16x16bit words. ATTACHEDDEVICEPAGELENGTH parameter is set accordingly in the GPMC configuration. Bursts are generated using the eDMA engine.

Sometimes I just need to read a single 16-bit register from the FPGA, which should be possible issuing a single memory access from the Cortex-A8. However, it is not clear how the GPMC will perform the external access in this case. From AM335x TRM:

7.1.3.3.10.5 System Burst Versus External Device Burst Support 
“When the system burst request length is less than the ATTACHEDDEVICEPAGELENGTH value, the GPMC proceeds with the required accesses.”

What "required access" means in this case? Should I expect a full burst (then the GPMC returns the requested word to the CPU)? Or only a single access is performed?

Thank you very much.

Part Number:AM3358

Dear all,

I would like to ask support about an issue I have using the AM3358BZCZ100 on my self designed board (produced by external company).

When I connect my laptop to the serial port of the CPU I can see that it's sending a C character for 5 times. After 5 times it stops.
When I connect the reset pin from the CPU (not the power chip) to the GND for a seconds, then after it's sending the C character again for only 5 times.
I do not have any SD card inserted which it could boot from.

I use the power IC TPS65217BRSLT. (Please visit the site to view this file)

Below I have the measured voltages using the signal names from the drawing which can be found here:  (Please visit the site to view this file)

VDDS_DDR = 1,84v
VDD_MPU = up and down from 1,12v to 1,08v
VDD_CORE = 1,08v
VDD_3V3A = 3,36v
VDDS = 1,8v
VDD_3V3AUX = 3,32v
PMIC_POWER_EN = 1,8v
PMIC_PGOOD = 1,8v
LDO_PGOOD = 1,8v
VDD_PLL = 1,8v
SYS_RESETN = 3,28v

Does anyone have an idea what could be the root cause?
Thank you in advance.

Hi,

in the example :NIMU_BasicExample_skAM437x_armExampleproject(pdk_am437x_1_0_10, CCS7), How do I make sure there is a Timer object in the SYS/BIOS configuration that is calling the driver function
llTimerTick() every 100 ms?

I can find a description: Global.ndkTickPeriod = 100 in the cfg script editor, but I can not find where it be set by the XCONF.
