Hello,
I'm trying to flash a customized FW in a PN7642 via I2c with the LPC55S16 companion board.
I've generated the esfwu file with Host Crypto Scripts (01.03), using as Transport Key the one for C101 chip (We have reworked our EVK board to solder a new C101 chip)
Step by Step Guide to update user firmware through host interface for PN7642
Custom (not secure) update fails with error 0x01.
If I flash the NXP FW (secure), version 03.00, works OK.
I suspect the HostScript configuration file is not OK for a customer FW.
I only modified it to change the aes_key from C100 transport key to C101 transport key.
Can I get some help?
Regards,
