This board is a pain to get working for the first time because the flash protection bits are set.

Check these resources to unlock the board for programming:

To flash this board with various rust utilities such as probe-run, cargo-embed, and cargo-flash remove the --connected-under-reset flag. This flag is required for the NUCLEO board, but will cause timeout errors with the LoRa-E5 development board.

⚠️ You must use recent versions of probe-rs based tools to avoid bugs with the STM32WL ⚠️

  • cargo-embed >=0.12.0
  • cargo-flash >=0.12.0
  • probe-run >=0.3.1
