Problem: DSK Diagnostics failed

Started by spon...@mail.ru March 17, 2008
Hello to everybody.

Withous any reasons my TMS320VC5510 DSK stopped to load and execute burned into flash program on boot. CCS runs, compiles, loads(w/o errors) and runs compiled programs, but there is no response from DSK.

When I run 5510 DSK Diagnostics Utility, the main test fails on Flash test stage. Tests on 'Advanced' tab pass all except 'Led/Swt'.

It seems to me that problem is in CPLD, because work with Flash memory chip(Flash_CEn signal) and with Switches and Leds are done through CPLD.

Maybe CPLD's program is damaged(why?).

I wanna try to test the CPLD's work via JTAG.

Or maybe I'm wrong and problem is not with CPLD.

So I ask you help, I'm very-very upset now :`(
