Did you know you CAN verify and flash the firmware on most hardware wallets (coldcard, trezor, bitbox, jade, krux, etc...), but you can NOT do that on raspberry pi based signers? All you can do on raspberry pi is replace the higher level OS in the SD card. They come pre-programmed from factory. Don't use raspberry pi for bitcoin security.

@nvk Verifying and flashing the firmware is important. We also need to be able to confirm that we have genuine devices (or parts).
@nvk How can I verify the filmware and how can I make sure is secure?
