Hi all. I have some trouble to connect SPC563M64 through USB Multilink. My device is in censored mode with configuration 0xAAAA_AAAA and serial password 0x1122334455667788. I try to uncensor device with this password, but have no connect.

In normal boot mode {[0],[0]} i can read contents of full Shadow block through CAN (by my software), so I'm sure what serial password and configuration word is correct. But i can't uncensor device.

In serial boot mode {[1],[0]} i can access CAN boot mode with password 0xFEEDFACECAFEBEEF and i have JTAG/NEXUS access without censoring with flash access diasabled (as it should be). So power, JTAG connections etc done right.

Power is stable, reset pulled up through 4K7 resistor. I tryed to connect MPC5674 with same censor configuration and JTAG uncensor pass with no troubles.

Any guess?

Hello Dmitry ,

i am not an expert of P&E USB Multilink. (i have not in my office)

I am using PLS DESTK.

Anyway, I will check in ST World.

I think that you should enter your private flash password in your debugger option

(Cf attachment coming from nxp side)

Best Regards

Erwan
