Description
There is currently a variant of the firmware for this architecture with which the device boots and the radio initializes, but LittleFS is not working. See #2265.
Should be a very low-power device as it uses the same processor as NRF52 (single-core ARM Cortex-M4) running at lower clock frequency, no Bluetooth, and the radio is integrated on the same chip.
This issue has been mentioned on Meshtastic. There might be relevant details there:

Is it really worth to develop this HW? It only has 256kB flash memory, if it ever works, it will be really limited, considering the that other ARM devices compiles to ~600kB binary file. It may be better to implement a stm32wb5mmg + sx1262 https://www.st.com/en/microcontrollers-microprocessors/stm32wb5mmg.html this will have Bluetooth and 1MB flash, just an idea.
