Hi,

I have the following error when I try to flash my proxmark with the last commit height.

$ sudo client/flasher /dev/ttyACM0 -b bootrom/obj/bootrom.elf

Hey!

I solved this issue by flashing the proxmark with a BusPirate and now I can flash it with flasher. Howerver I'm still interested if someone know the root cause of the error. Is it something related with the Lock Error Bit (I had to flash protect 0 0 15 off during the JTAG flashing) ?

Unexpected reply 0x00fe (expected ACK)

0x00fe means NACK. This response is sent when trying to flash to an invalid address, when the programming keyword is wrong, or when lock bits are set. The former two "should never happen", so your assumption about the lock bits should be correct.

ThePirateWhoSmellsOfSunflowers commented 3 years ago

I have flashed the proxmark multiple times before the issue, I don't know why this time lock bits were set. Howerver, thanks for your response.
