Problem with Flashing from Ubuntu: "Write failed: no error!"

Sorry if this is in the wrong forum or if this is a trivial question. You'll have to bear with us-- we're new to working on the proxmark.


Here's the issue: I'm sure it's probably something simple, but we're a bit at a loss now and would really appreciate a bit of guidance. We are trying to flash our board using the 486 revision of the proxmark code. (We need an older version to get another set of independent code functioning properly on it...) We go through the process for flashing and get this output:

ghaddock@grayling-HP:~/proxmark3-t55x7/client$ sudo ./flasher ../armsrc/obj/osimage.elf
Loading ELF file '../armsrc/obj/osimage.elf'...
Loading usable ELF segments:
1: V 0x00110000 P 0x00110000 (0x0000f8ac->0x0000f8ac) [R X] @0xb8
2: V 0x00200000 P 0x0011f8b0 (0x000021f0->0x000021f0) [RWX] @0xf968
Note: Extending previous segment from 0xf8ac to 0x11aa0 bytes

Have a nice day!


As you can see, our laptop seems to recognize the proxmark and goes through the process of flashing but then it returns a "write failed: no error!" Testing the board afterwards shows that the flash was not successful.

We thought that there might be something wrong with the bootrom we were using, so we tried flashing an older version of that, but we got the same error-- it seemed to work fine and then returned "write failed: no error!"

Anyways, does anyone have any idea what might be going on?

Re: Problem with Flashing from Ubuntu: "Write failed: no error!"

For anyone interested, it turns out that the osimage was successfully flashed on all the while. It's still unclear why it said "write failed," but everything is operating perfectly now!
