Wrong flashboot on the NTDK20FA CPU

[koko30]

Hi,

we have a customer who has a Rls23 (NTDK20AB CPU with NTDK34AA_R10 Flashboot) and in this system the CPU has damaged.

My colleague has brought a newest NTDK20FA CPU, and he installed the Rls 23 software, and after that he put the NTDK34AA_r10 (Rls23) Flashboot to the NTDK20FA CPU. (The original was NTDK34FA_R06) I know it is not compatible, but he did it already.

Since that time - before the "Power up self test passed" message - the processor rebooting cyclically,
and not react to the Control-I or to the FBUG (NTDK34FA CPU) :

Have you any suggestion how could we put back the NTDK34FA_R06 Flashboot, and boot up the NTDK20FA CPU ?

I erased the Security ID from the messages, but i don't know why we can't see the System ID while the Dongle is there on the CPU ?

Thanks in advance

boot up on a pcmcia card with release 23.xx on it. When you get the menu go to utilities and there is a flashbootrom option there. Just load the flash bootrom from there. You have to have the rls 23.xx you have the keycodes for.

I've tried it with different flashcards and with the Rls 24.47 software (and after with different OS - 24.25,25.15,25.40), just the CPU not react to the Control-I command and after the Executing power up selftest the CPU rebooting.
