Flashing

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:

• How to program a LoRa-E5
• seeed-lora/LoRa-E5-LoRaWAN-End-Node
• stm32wl-unlock

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
