Hello,

I'm debugging the TC277 with Trace32, I'm testing the Standby mode of the MCU, after I set it to the standby mode, the Trace32 is down, and I tried to download again, it's debug port secured.

Does anyone have ever seen this error before? how to fix this?

Either you erase the UCB area and it's other configuration or your initial memroy of DSPR,PSPR and LMU is correpted which is used by the BOS software. You can try to clear it from trace or some other debugger tool.

I am getting the same error "Debug Port Secured" on TC37x.
I was trying to flash HSM software using Lauterbach after checking that HSM is disabled. By mistake I did flashed the wrong .s19 as HSM software and then enabled the HSM.
Now I am not able to do any thing. It seems I am locked out of the ECU.

Is any body know any procedure so that I can unlock the ECU ?

If the .s19 does not contain a valid vector table and the PROCONHSMCS UCB doesn't point to this sector and you enabled the HSM. You cannot recover it, the device is no longer usable (i.e Bricked).
