TMS320C5505: How to set USB function to testmode

Is there any sample code for entering USB test mode on C5505?

We would like to do the USB device high speed test.

It seems that chip support library of C55x does not support USB test mode function.

I think it seems OK to set INDEX_TESTMODE register to appropriate value if the C55x receive the device request

(SET FEATURE, TESTMODE feature)

Hi,

I've notified the C5000 team. Their feedback will be posted here.

Best Regards,

In the CSL package for C55x, please take a look at C:\ti\c55_lp\c55_csl_3.07\demos\out_of_box\c5545\c5545bp_software_01.01.00.00\source_code\c55xx_diagnostics\board\diag\usb_test\src\usb_test.c

This test is for the C5545, but should give you some guidance on what the code should look like.

Hi Lali,

Thank you for the information about the chip support library.

I found the following USB Test Packet data:

const unsigned char test_packet[53] = { .... }

But there is no code which the above array is used in the library.

How can I use this array, and how can I send the USB Test Packet from C5505?
