Hi,

I have a question about MMU configuration in cfg file and the second argument of USBD_bulkRead ().
・Mmu_setSecondLevelDesc(Ptr virtualAddr, UInt64 phyAddr, Mmu_DescriptorAttrs *attrs);

If the relative address and physical address are different in the MMU settings, the received data could not be confirmed even if USB data reception was detected.

However, if the relative address and the physical address are the same address, the received data could be confirmed.

Question:
Why does this happen?
Please let me know if you have the necessary settings.

Hi,

we are planning to connect a FPGA to the AM5728 using the GPMC interface and memory mapped access. At Linux I only found a gmpc NAND driver. Can we use this driver to configure a generic memory mapped device via GPMC?

Is there an example doing this?

best regards,

Joerg

Hi,

I have another quesion about the MMC/SD card controller,because of the limit of SDIO spec 2.0 ,the max clock for the SDIO is 50M,

The MMC/SD card controller supports MMC (Multimedia Card) Specification v4.0，is the max clock also 50M or more?

Thanks.

Hi,

I have successfully build and put the image on the sd card. I can get into the root and when I tried to run app.out it keeps on running attaching to ipu1 and other processing units without showing any particular display of the demo usecases. Can anyone help me figure this thing out? (Please visit the site to view this file)

Hi,

Dynamic steeting guidlines tda2xx_evm_robust_rvc

Using SDK_VISION_03_02_00_00 and RVC release for tda2xx_evm_robust_rvc.

I'm able to display video on DISPLAY_LINK_INST_DSS_VID2 and Grpx (static steeting guidlines) on DISPLAY_LINK_INST_DSS_VID3

Do you know if is possible to make it dynamic (move lines at runtime ) ?

Hi

We would like to thoroughly test the DDR3L interface of our AM5748 board. We are running Linux.

There is "memtester" in Linux which writes/reads back several test patterns. Is there another tool which also takes timing parameters into account, meaning it adjusts certain parameters until there is an bit error so we get some kind of information regarding timing margin?

Is there also a tool to verify ECC functionality? Which prints out the value of related registers?

Thanks and best regards,

Roger

Will redundancy protocols like DLR,MRP and HSR are implemented in PRU-ICSS(i.e. hardware level), or it should be a part of protocol stack of Ethernet/IP, Profinet ?

HI

I am developing the product using tms320c6678device.
The environment and specifications I use are as follows.
   - CCS 6.1 (IDE)

   - SYS/BIOS 6.33.06.30

   - IPC 1.24.3.32

   - OpenMP 2.1.16.3

   - MCSDK 2.1.2.6

   - PDK (6678) 1.1.2.6 

   - XDC 3.23.4.60

To use OpenMP, make eight cores into one group and burn the same image in one group.
If the code to initialize the Clock Module during development is inserted, the following error occurs.

How do I use the clock module in my environment?

[C66xx_0] ti.sysbios.gates.GateMutex: line 97: assertion failure: A_badContext: bad calling context. See GateMutex API doc for details.
xdc.runtime.Error.raise: terminating execution

Clock examples were available on the SYS/BIOS Generic assembly, a sample project provided by the sample project. (One core execute)

Hi

Our customer is developing AVM using vision sdk.

I know there is no HDMI EDID read software code in the vision sdk.

Do you have HDMI EDID read Software code patch.

If yes, can I share it?

Hi,

I'm working with the platform DM8127 IPNC.  In order to adapt to my existing environment and procedures, I need the package IPNC_RDK_V3.8.0-Linux-x86-Install.bin.

But on TI website I can only find the version IPNC-RDK-CSK-3.9.1-Linux-x86-Install.bin.

Where and how can I get the previous version of the resource (IPNC_RDK_V3.8.0-Linux-x86-Install.bin)?

Thanks in anticipation of your support.

Regards,

I am currently getting familiar with the TMS320C672x DSP Dual Data Movement Accelerator (dMAX) and how to service the McASP. The Reference Guide (spru795d_dMAX.pdf) has a single example for the McASP interface but because there are numerous ways to move data, it doesn't explain how to configure my particular interest.  Is there technical staff available at TI that have in-depth knowledge of the transfer possibilities for the McASP peripheral?  If so, I could follow-up with my particular example parameters and needs.

Thank you much,

I'm using AM3358 SoC on Beagle Bone Black compatible board. I want to use DM timers (timer 6 and 7). But I can't read from timer 6's control register. I do it the following way:

.....

#define TIMER6_BASE_REG 0x48048000

.....

....

    printk(KERN_INFO"!!!Trying to read Timer6 register manualy with readl...\n");
    printk(KERN_INFO"!!!Timer6 control register address:%x...\n",TIMER6_BASE_REG + (OMAP_TIMER_CTRL_REG & 0xff));
    
    void __iomem *io = ioremap(TIMER6_BASE_REG + (OMAP_TIMER_CTRL_REG & 0xff), SZ_4K);
    printk(KERN_INFO"!!!Remapped address:%x...\n",(unsigned long*) io);
    printk(KERN_INFO"!!!Trying to read...\n");

....

    //omap_dm_timer_enable(cpts->odt);
    //omap_dm_timer_enable(cpts->odt2);

    unsigned int address = 0;
    address = readl(io);
    printk(KERN_INFO"!!!Value:%x...\n",address);
    printk(KERN_INFO"!!!Reading done succesfully...\n");


This causes page fault as far as I understood. Here is dmesg output:

I tried to read from ethernet registers the same way (from 4a100000 physical address) and it's working fine... My guess was that I couldn't access the DM Timer control register because the timer itself (or the clock of the timer) were not enabled and I tried the following before accessing register:

omap_dm_timer_enable(cpts->odt);
omap_dm_timer_enable(cpts->odt2);

Also I tried to comment the following string in /drivers/clocksource/time-ti-dm.c in omap_dm_timer_prepare function:

//omap_dm_timer_disable(timer);

Nothing seemed to help...

I am using buildroot to build zImage. The kernel is 4.14.40 linux kernel from git://git.ti.com/processor-sdk/processor-sdk-linux.git (SDK 5.0, commit 47961). My device tree andre attached to the post. What can be the problem, why I can't access DM Timer control register?

HELLO

JUST WONDER WHAT IS EXACT PURPOSE FOR DSP / M4 BUILT-IN TDA3 CHIPSET.

Q1:

IS M4 A STATE-MACHINE TO HAVE MINIMIZED / TAILORED CODES CONTROL EVE / VIU / DISPLAY SUBSYSTEM? IN OTHER WORDS M4 ONLY TAKE CHARGE OF DATAFLOW / CONTROLFLOW CONTROL? AND ALL TASKS ARE IN PROCESSING WITH EVE / DISPLAY SUBSYSTEM / DSP?

Q2:

IS RTOS TARGET AT RUNNING UPON DSP / M4?

Q3:

IS DSP A SELF-BOOT TYPE DSP / ASKED TO LOAD BOOT CODES FROM EXTERNAL FLASH?

ARE ALL INTERFACE:

UART

I2C

SPI

PWM

GPIO

McASP

CAN

ETHERNET

DIRECTLY CONTROLLED BY M4 / DSP?

Q4: HOW TO CONFIGURE RIGHT CLOCK SOURCE FOR BOTH OF DSP / M4?

Q5: HOW TO SET UP REQUIRED IOS FOR BOTH OF DSP / M4?

Q6: HOW TO SETUP McASP BYPASS AND ROUTE OUT TO CODEC WITH DAC?

Q7: CAN DSP SUPPORT AUDIO CODEC / AUDIO PROCESSING SDK?

Q8: HOW THE DSP / M4 COMMUNICATE WITH EACH OTHERS? BY IPC? BY SHARED MEMORY?

Q9: HOW TO CONTROL DATAFLOW FROM INCOMING TO OUTGOING? FOR EXAMPLE HOW TO PIPELINE VIDEO FRAMES?

Q10: DOES DISPLAY SUBSYSTEM SUPPORT INVERSION FUCTION TO ROTATE OUTPUT VIDEO FOR DIFFERENT DISPLAY ORIENTATION?

Q11: DOES DISPLAY SUBSYSTEM SUPPORT POP (PICTURE OVER PICTURE: 2 INCOMING VIDEO OVERLAY IN A DISPLAY) / PIP (PICTURE IN PICTURE: 2 INCOMING VIDEO INSIDE ANOTHER IN A DISPLAY). IT IS TO SAY SUPPORY LAYER CONTROL FOR ANY 2 DIFFERENT INCOMING VIDEO FOR AN OUTPUT TO ONE DISPLAY.

Q12: DOES RTOS WITH ENOUGH DRIVER SUPPORT FOR TDA3 WITH LESS OF A15 / GPU  TO CONTROL EVE / VIU / DISPLAY SUBSYSTEM DIRECTLY / DDR / EMMC / SD CARD?

Q13: DOES SDK SUPPORT FILESYSTEM TO BE BUILD UPON DSP? M4?

Q14: DOES SDK SUPPORT ETHERNET DRIVER / PROTOCOL STACK?

Q15: DOES SDK SUPPORT CAN DRIVER WITH CAN PROTOCOL STACK INCLUDING CAN IL?

Q16: DOES SYS/BIOS RTOS SUPPORT THIRD PARTY GUI TOOL / LIBRARY? OR TI HAS SELF-BREW TOOL TO DEVELOP LOW END AUTOMOTIVE AROUND VIEW PRODUCT? GENERALLY DEVELOP GUI BY OSD WITHOUT SPECIFIC TOOL SUPPORT IS VERY A TOUGH CODE JOB.

Q17: CAN PWMSS DIRECTLY BE USED IN DISPLAY BACKLIGHT CONTROL?

Q18: CAN DISPLAY SUBSYSTEM SUPPORT TRANSPARENCY PICTURE?

Q19: CAN DISPLAY SUBSYSTEM SUPPORT PICTURE MASK FUNCTION?

Q20: HOW TO CONTROL DDR? BY DSP? M4?

Q21: HOW TO DEAL WITH INCOMING PACKET FROM ETHERNET IF YOU DON'T SUPPORT PROTOCOL STACK AND PARSER IN YOUR SDK?

Q22: CAN YOUR SUPPORT TSN ETHERNET TRANSCEIVER?

Q23: CAN VIU SUPPORT BT.656 WITH DEVICE LIKE TECHPOINT HD-TVI RX 4 CHANNEL 1080P / 60FPS? AT LEAST DUAL CHANNELS?

Q24: ANY SUGGESTION TO SYSTEM POWER DEVICE SELECTION?

Q25: CAN DCAN / MCAN BE SET FOR THE OTHER USES? FOR EXAMPLE UART INTERFACE? GPIO?

Q26: DOES SDK CONTAIN SAMPLE CODES FOR M4? / DSP?

Q27: DOES CCS SUPPORT TO SETUP IOs FOR M4 / DSP?

Greetings,

For the past few weeks I have been getting acquainted  with TI-RTOS on a BeagleBone Black. I have an XDS200 connected and can happily debug my test apps with the CCS8.2.environment.

I understand about pin-muxes, have rebuilt the binarys, have modified board files to suit my devices, and have written apps to exercise a number of UART channels, I2c and USB devices. So far so good.

Now I come to the PRU's - the classic setup code:

int32_t ret = PRUICSS_socGetInitCfg(&cfg);
if (ret != PRUICSS_RETURN_SUCCESS) return (ret);

hPru = PRUICSS_create((PRUICSS_Config*) cfg, PRUICCSS_INSTANCE_ONE);

The PRUICSS_create call causes a "CortexA8: Unhandled ADP_Stopped exception 0x800249A8"

Within the PRUICSS_create function is a memory read of address 0x4A326000 to stash the device version into a config stucture. The function uses CSL_REG32_RD to do the read. The return address from this function is not that that was placed on the stack, so a car crash ensues. Why? What magic is happening here?

I added :

var peripheralAttrs = {
type : Mmu.FirstLevelDesc_SECTION, // SECTION descriptor
tex: 0,
bufferable : false, // bufferable
cacheable : false, // cacheable
shareable : false, // shareable
noexecute : true, // not executable
};

// Define the base address of the 1 Meg page the peripheral resides in.
var PruBaseAddr = 0x4A300000; // PRU_ICSS memeory space

// Configure the corresponding MMU page descriptor accordingly
Mmu.setFirstLevelDescMeta(PruBaseAddr,
PruBaseAddr,
peripheralAttrs);

to the .cfg to disable the cache at the PRU region, but this didn't fix the issue.

I then tried "Cache.enableCache = false" and "Mmu.enableMMU = false" in the .cfg to discount the obvious, but still the return address is corrupt.

I have done numerouse project cleans and rebuilds between code changes, and a final gmake clean / gmake on the PDK (v1.0.13 btw)

Help

Bruce.
