Problem: DSK Diagnostics failed
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 :`(
