Hello everyone,

I have made a custom board using Murata LoRa SOC and I am trying to flash it using Flash Loader Demo by STM and I am able to flash the code only once out of 10 times. The application shows 'Stopped Working' after coming to Device select.

Is there any other software to flash the ICs by UART?

Thanks in Advance

Seem to recall there being an open-source loader application, and the protocol is well documented. Here we wrote our own loader application.

The System Loader expects Even parity, and the pattern recognition is a one-shot test. If the loader doesn't recognize the 0x7F pattern properly you would need to restart the process. In a production test/programming implementation you need to be able to control the reset line, and have retry methods if the 0x7F/0x79 connection fails.
