TC3XX - debug port fail with pflash ucb configuration

[Rama]

Hello,

I am having an issue to connect debugger port after updating the PFLASH ucb.

Here are the pflash UCB configurations:

PROCONPF 80000000

RPRO Configured

PW0 03020100 PW1 07060504 PW2 0B0A0908 PW3 0F0E0D0C
PW4 13121110 PW5 17161514 PW6 1B1A1918 PW7 1F1E1D1C

CONFIRMATION 43211234 UNLOCKED ^confirm+

Looks like debug access is locked and PFLASH protection is enabled (once RPRO bit is set, the SSW will lock the debug interface ). Is there any way to recover the card?

Note:

HSM is disabled

Hi, is it an Infineon development board?
