sounds like a hardware issue with your device.

sounds like a hardware issue with your device.

maybe，just wonder is anyone else has the same issue。

[iceman1001]

you can try flashing some more but in my experience its your hardware that seem to be faulty

[4ft35t]

my  workaround is compile two fullimage.elf, lf only and hf only, to use the latest feature. LOL

Hello!

I have taken out of the closet my two proxmark easy (I currently use proxmark3 rdv4). I have configured Makefile.platform for PLATFORM=PM3GENERIC and I get the same problem on my two proxmark easy

This did not happen before, I have always been able to flash my proxmark easy (512K) with this firmware :)

[iceman1001]

@joelsernamoreno What does your output look like when you flash?

[joelsernamoreno]

Hi @iceman1001

My steps:

1.- The bootrom flashing is OK:

2.- Full image error:

3.- I can edit Makefile.platform like this:

4.- With the Makefile.platform edited, no errors when flashing fullimage:

Flashing fullimage only works if I remove LF, FELICA, and HITAC in Makefile.platform.

If I use other combinations like: LF and FELICA, LF and HITAC or just use PM3GENERIC, I get the error.

I hope this can help others. I use RVD4, but today I was bored and tried to update my old proxmark and got this error

Cheers!

Still looks like your ARM chip onboard flash memory is corrupt.

Just a note, the next release does not give problems here:

proxmark3-v4.9237
