I've got a problem downloading and programming flash on the tms320f28075. This is the 2nd spin of our custom board so that might be the problem but we're having trouble tracking it down. The other difference is that we had tmx parts on our first spin and on this one we have the qualified tms parts. I'm using the xds100v2 emulator. Here's the error:
C28xx_CPU1: Error: Failed unlocking device (zone 2) during Flash Operation.
C28xx_CPU1: Error: (Error -1135 @ 0xC0CC) The debug probe reported an error. Confirm debug probe configuration and connections, reset the debug probe, and retry the operation. (Emulation package 6.0.14.5)
C28xx_CPU1: Trouble Halting Target CPU: (Error -1044 @ 0x0) The debug probe reported an error. Confirm debug probe configuration and connections, reset the debug probe, and retry the operation. (Emulation package 6.0.14.5)
Immediately after receiving this error I can do a emulator connection test with success.
These parts also have the linestream library programmed into sector N, but this also was the case with the tmx parts on our 1st spin. I believe that is the reason for the "Failed unlocking device (zone 2)" message above. We also received this message on the 1st spin but are able to program flash.
I can download and execute the blink_cpu01 demo program to RAM with no problems.
Any help to debug would be appreciated.
