Hi team, I have purchased a development kit (LoRa-E5) from Seeed website. I would like to know the method to flash the code into the controller without using STM programmer (ST-link). Is it possible to do this way?
Thanks.

Attention
1. Factory AT Firmware is programmed with RDP(Read Protection) Level 1, developers need to remove RDP first with STM32Cube Programmer. Note that regression RDP to level 0 will cause a flash memory mass to erase and the Factory AT Firmware can't be restored again.
2. The "PB13/SPI_SCK/BOOT" pin on the Wio-E5 module is just a normal GPIO, not the "BOOT0" pin of the MCU. This "PB13/SPI_SCK/BOOT" pin is used in the bootloader of the Factory AT firmware, to decide to jump to APP or stay in bootloader(for DFU). The real "BOOT0" pin doesn't pinout to the module, so developers need to be careful when developing low-power applications.
