TC38xx can't connect to target via MEMTOOL

[mohammedatdenso]

Hello,

I tried to flash the TC38x microcontroller ECU and it failed but now I am unable to communicate/connect or flash the TC38x with the Infineon MEMTOOL via MiniWiggler. I think the TC38x target is locked, as I can see an error as IF_LCK . Can you let me know how to unlock the target device. I am thinking probably I should reset the microcontroller but cannot find the right procedure.

This is the error message: 

MEMTOOL Error messages:
Controller0.Core0.Tc2CoreTargIntf: Can't connect target !
Controller0.Core0.Tc2CoreTargIntf: Can't connect target device via DAS !

Hi,

do you have a custom board or a triboard?

Hi mohammedatdenso,

Have you modified UCBs of TC38x? If you bricked the chips, it cannot recover.
