Hi,

Can AM3354BZCZD80 work at more than 1GHZ, do we have successful story or suggestion about that?

customer want to shorten the switch on time by doing this.

Thank you!

Part Number:TMS320C6747

Hello,

My customer is needed to move over from the current DA810 to C6747 without hardware design change. They would like to confirm unused pin handing for USB1_DP and USB1_DM. C6747 datasheet mentions those pins should be leaved unconnected. But in the current DA810 based HW design, those have been connected to GND (Because those pins are regarded as GND pins in DA810 datasheet). 

Do you have any concerns for leaving those pins connected to GND ?

Best Regard,
NK

Part Number:66AK2H06

Hi

I have following queries..

1) How many MACs are there in 66AK2H06 ?

2) Are all are configurable ?

3) Is it possible for any device (connected at port 1) to exchange data with any other device (connected at port 2 / 3 / 4) without passing it through processor (i.e at port 0) ?

4) if it is possible (point 3 above), can we restrict it with the use of MAC IDs ?

Regards

Part Number:PHYTC-3P-PHYCORE-AM335X

Hello TI,

We are using  hardware Interrupt pacing feature provided by Ethernet Subsystem of AM335x processor for our project.  The idea here is to limit the number of  Receive interrupts that occur during a given period of time, so that the hardware withstands network storm,in-turn avoid load on CPU.

To Enable the Interrupt pacing feature, we have used the following initialization steps in the below mentioned order.

1. Configured the maximum number of interrupts per milli second to 8.
2. Set the Prescaler value to 1600 based on certain calculation like main clock frequency and max number of interrupt per milli sec.
3. Enable the Interrupt pacing feature in the hardware.

With the Prescaler value set to 1600, we are observing that, when the CPU is subjected to network storm(100Mb/s) for a longer duration( 2+hrs), Ethernet subsystem stops receiving the Incoming RX interrupts for Infinite duration of time.We have to manually Power cycle the  CPU for things to work again.

I verified the Prescaler value  with the Linux CPSW driver which uses Interrupt pacing feature. I noticed that Prescaler value of 500 is used . When I used the value of 500 in our driver code, things started working fine during storm test.

NOTE:

1. When Interrupt pacing is disabled, this issue is not observed

2. We are using VxWorks RTOS

My question here is: 

1. Do we  have any such Prescaler value limitation.
2. Have you encountered any such issue in the past.

Part Number:TMDSEVM572X

Hi,

I would like to know if TI can share the PCB design files- gerber data and PCB stack-up-  for the TMDSEVM572X EVM card. This is required so that we can follow a similar approach in our design.

Part Number:PROCESSOR-SDK-AM437X

Hello E2E community,

I need to implement a bootloader on my AM4377-based custom board. It has SDRAM slightly different from IDK or GPEVM board, it is DDR3L MT41K256M16TW-107 AAT.

The SDRAM timings are different from IDK/GPEVM boards, I use specific gel files and my projects run fine on this board when loaded from CCS. I can prepare the bootable MicroSD card for IDK board and it works like a charm (I put my MLO/app files). But when I take "ti\pdk_am437x_1_0_14\packages\ti\starterware\bootloader" as example, adjust timings, rebuild with this command:

gmake bootloader BUILDCFG=boot PLATFORM=am43xx-evm BOOTMODE=mmcsd

and put the binary with TI header to the SD card:

bootloader_boot_mmcsd_a9host_debug_ti.bin -> MLO

Then nothing is working! My board just keeps complete silent about any attempts to boot from SD card. I don't see any messages! Neither on console nor on serial port.

The SYSBOOT lines on my custom board to select the boot devices are set to the EXACT same values as for IDK_AM437x board.

As shown below, on IDK_AM437x board only signals SYSBOOT[3,4,14] are connected to 3.3VDC, others are grounded.

On my custom board they are routed exactly same way:

I check the CTRL_STS register:

IDK_AM437x board, CTRL_STS (0x44e10040)  = 00400318
Custom board, CTRL_STS (0x44e10040)          = 00400308

CTRL_STS register on my board is different (1 bit is different), but I tried to set it through CCS to the same value as IDK board and it doesn't change anything.

I'm trying to understand what's wrong with my boot loader and added debug messages to "starterware\bootloader\src\sbl_main.c"

int main(void)
{
    uint32_t status;
    uint32_t imageSize;

    printf("Hello world, from the bootloader!\n"); /* !!! */

    status = BOARDInit(NULL);
    if(status != S_PASS)
    {
        printf("** BOARDInit() returns error!\n"); /* !!! */
        return 1;
    }

But I don't see any messages during board boot.

** My questions **

1. How do I debug the boot loader?

2. Where should I set the breakpoint?

3. Even if my SDRAM timings are wrong, I still have to see at least printf() messages, why don't I see them?

Any help will be very appreciated as I'm really stuck and not sure how to resolve this issue and make my custom board boot from MMCSD.

Thanks a lot!

from the above data, we have 1200hz&2200Hz data.

I tried to encode manually it was wrong (because sometimes sample for 1200Hz and 2200Hz are same)

After I tried using Georztel algorithm to find 1200Hz & 2200Hz. But that code was not detect the two frquency.(i attach the code below)

Can I use FFT algorithm to detect this frequency ??

can anyone help me to solve this problem.

Part Number:TDA2EVM5777

Hello,

I am using VisionSDK 3.06 on TDA2x EVM. I have to build a use-case for BIOS build. The use-case contains an algorithm link. This link encapsulates an algorithm which contains OpenCV and C++ constructs. I am thinking of hosting this algorithm link on the A15 core of TDA2x.

I have the following queries:

(1) Does TI support OpenCV on A15 core with VSDK 3.06? ----> reason to ask this question is that I read in another forum thread that TI was planning to deprecate OpenCV support after VSDK 3.03.

(2) What version of OpenCV is supported on the A15 core? ----> this is to ensure that our algorithm is not using any advanced version of OpenCV that TI cannot support.

(3) VisionSDK has separate build configurations for BIOS and OpenCV builds. How can I create a build configuration for BIOS that also includes OpenCV?

(4) VisionSDK documentation consists a guide to enable OpenCV and OpenCL with VisionSDK Linux. Where can I find the steps to enable OpenCV for VisionSDK BIOS? ----> I am planning to use BIOS on A15.

(5) Where can I find exact information on the support for C++ constructs on the A15 core? ----> it would be nice if you can provide name of the exact document.

Thank you.

Tool/software: TI-RTOS

Hi,

We are designing a system based on the AM5728. We will be running Yocto Linux on the A15 and RTOS on the DSP's (and M4's).

We will be using all 4 spi ports to read in adc data continuously. We need to get this data into the DSP's for processing. Once processed we will be making the results available to the Linux core.

As this is a real time application, we need to get the SPI data into the DSP's directly. So my question is, is it possible to configure the DSP cores to have control over the SPI peripherals (and some GPIO and UART for that matter), and if so how to go about that?

Thanks

So we are attaching the u-boot files and kindly have a glance on the dts files attached and help us to load the logo in the u-boot and to get the backlight in the u-boot. If that case is not possible could you suggest any other method to load the logo mainly before loading the application.

Part Number:AM5728

Tool/software: TI-RTOS

Hello, TI Experts,

Our customer sent us questions about "how to remove EMIF2-DDR" by using TI-RTOS(PROCESSOR-SDK-RTOS-AM57X).

They developed their custom board by removing DDR2 connected to EMIF2 referring TMDXIDK5728.

And they try to create their application program by using PROCESSOR-SDK-RTOS-AM57X.

They want to know how to modify "idkAM572x_ddr.c" for removing EMIF2-DDR.

So, they created the "idkAM572x_ddr.c" like below way.

   - They use "idkAM572x_ddr.c".

   - They change "Board_STATUS Board_DDR3Init()" by copy & paste from "idkAM571x_ddr.c".

     (Because TMDXIDK5718 is used only EMIF1-DDR).

Please refer attached pdf file in detail modification.  

Question:

  They said it seems to run properly their custom board with their above modification.

  Is it OK to use for their mass-production product?

We would appreciate if you tell us the proper/successful way of removing EMIF2-DDR including how to modify "idkAM572x_ddr.c".

If there are any notice or comment for their modification way such as pasting from " idkAM571x_ddr.c", please also tell us.

Can someone help what exactly is this error and how to resolved it??

Tool/software: Linux

Hi,

We have designed our board with ADV7401 to capture componenet FullHD Y:Pb:Pr BIT 1120 IN AM5728,

There is currently no Linux driver for the ADV7401 available.

we need a linux driver support in V4l2 frame work  and compatible to VIP in AM5728,

please suggest,same  Decoder IC from TI??

thanks
