TMS320F28388D: Issure fwhile flashing CPU1

Part Number: TMS320F28388D
Other Parts Discussed in Thread: UNIFLASH

Hi,

I'm facing an issue I never had before when trying to flash CPU1 of a TMS320F28388D.

Context:

Development IDE: CCS v20.2.0 (the IA)

I know my code is working because I've flashed something like 5 other boards before with the same FW and it's working fine. I load directly a hex file that I create with post-build steps.

I'm flashing the TMS320 via Uniflash, I use XDS110.

GPIO72 / GPIO84 are tied to 1 always. I never changed boot pin configurations.

When I try to flash CPU1 (or even erasing it), I get the following issue, see screenshot 5 ERROR at the end.

I've flashed the CPU2 before (so JTAG is working, not hardware problem). I know I should have flashed CPU1 first. Can it be a problem ?

I erased Flash of CPU2, it works but I still have the problem. It's like Flash of CPU1 is corrupted.

Any suggestions to try before replacing the component ? 

Thanks,

Adrien
