Errors flashing the PM3 Easy devices with a generic build (MacOS)

[maxieds]

Describe the bug There are errors flashing the PM3 Easy line of devices using pm3-flash-all on MacOSX. The generic build of the firmware is installed by running

brew reinstall --with-generic proxmark3

where the Homebrew package is, as usual, the tap provided by this repo (Icemann/RFIDRes). Then when I plug in the Easy device over USB, and run the flash command, the following is the full output I get:

$ pm3-flash-all

Note that I am able to build a RDV4 firmware image from source and flash it to the other device using the corresponding command.

Additional context Other users on Discord have noticed the error. No apparent fix is known for the bug.

Note that the version of the PM3 Easy device I have does have 512M available.

[doegox]

ok so you've trouble flashing the pm3 easy on OSX?

Did you use --with-generic as mentioned at https://github.com/RfidResearchGroup/homebrew-proxmark3 ?

Did you try the steps described in the error you pasted ?

[!!] 🚨  1)   ./pm3-flash-bootrom
[!!] 🚨  2)   ./pm3-flash-all
[!!] 🚨  3)   ./pm3

[secit-pl]

In some cases you need to hold the PM3 button all the time while flashing firmware (that was in my case).

[maxieds]

@secit-pl Thank you! Thank you! Thank you! Holding the button down while running

pm3-flash-bootrom && pm3-flash-all

Fixed the problem. :)

@doegox Perhaps we should consider creating a WIKI or docs page just for PM3 Easy users?
