TMS320F28375S: TMS320F28375S USB Driver installation

Hi Digvijay,

Have you tested your custom board's USB communication by running the USB bootloader per Sal's suggestion in the previous thread? I think this is a good step to take to verify that your device's USB is configured correctly.

Please look at the example within C2000ware:

C:\ti\c2000\C2000Ware_1_00_06_00\utilities\flash_programmers\usb_flash_programmer

Best,
Kevin

Hi

                Thanks for the reply.

                  I was able to sign in and install the drivers. Also i have implemented the usb_dev_serial_cpu01 example. I have one doubt though.

From where i can set USB Data rate(12 MBps or 1.25 Mbps)??

Can it be set from software or is it depending upon hardware??

Regards,

Digvijay

Respected sir/madam,

                              Please reply ASAP.  It is urgent.

I was able to implement the usb_dev_serial example. I have integrated this example into my code. The are no errors while building my code. But while implementing the example there is certain issue.

When i dump the usb_dev_serial example using debugger and after that immediately dump my code using debugger , my code works fine. But  when i try to dump my code separately it does not work. Also when i power cycle the controller with my code, it does not work. The message that USB device has malfunctioned pops up.

So what could be the reason??

I have attached the snaps of pop up and device manager.

Regards,

Digvijay

Hi,

        i have attached my 2837xD_FLASH_lnk_cpu1.cmd   file.  Please reply asap.

Hi Digvijay,

I'm not clear what you mean by the below:

When i dump the usb_dev_serial example using debugger and after that immediately dump my code using debugger , my code works fine. But  when i try to dump my code separately it does not work. Also when i power cycle the controller with my code, it does not work. The message that USB device has malfunctioned pops up.

I'm guessing you mean when you run your application from flash and power cycle the board the USB is not appearing configured.

I would first suggest checking your boot mode selection pins. After programming your device for standalone flash operation make sure you set the boot mode to one that will boot from flash, Get Mode defaults to running from flash so try that. Do this before power cycling the device:

If that doesn't fix this then maybe you're not allocating flash properly or you need to copy functions from flash to run from RAM, like below:

#ifdef _FLASH
    memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, (size_t)&RamfuncsLoadSize);
#endif

best,

Kevin

Respected sir,

                          Device boot mode is not the problem. Also i tried copying function from flash to ram, but it does not work. So only option left is memory allocation of flash. I tried changing the 2837xD_FLASH_lnk_cpu1.cmd  file. But i am not able to figure out which part  to change. It is giving errors like memory overlap. I have copied the 2837xD_FLASH_lnk_cpu1.cmd into previous reply.

So can you please point me to a part , which i need to change to get USB working from flash??

If possible please share .cmd file for USB from flash.

Regards,

Digvijay

Respected sir,

               As you suggested i tried using  2837xS_Generic_FLASH_lnk.cmd     file with USB_dev_serial example for single core. But it is giving following errors when i use memcpy() and initflash_bank0() functions.

               So what could be reason??

Hi Digvijay,

That address location is the ITRAP ISR in BOOT ROM. Something went wrong.

Have you made any changes to the example or linker command file? I don't believe there are any issues with this example out of the box, I tried the dual core version and it seems to work fine. Try using the cmd file provided below if so:

Maybe there's something wrong with your board. Have you tried running any of the other example projects in C2000ware?

                  I have not made any changes to the example or linker file.
