Bare Metal Program - Adafruit RP2040 LoRa - Feather
First time MCU programmer here. The current goal is a minimalistic firmware with basics, defining the memory map, booting, setting clocks, and blinking an led. Using C language. Raspberry’s RP2040 is an Arm cortex M0+. No plans to play with the LoRa chip right now. Considering I am an embedded systems beginner I figured it’s worth it to reach out to community to see if there are obvious speed bumps I haven’t recognized with this board:

I'm looking into ThreadX intergration with RP2040 boards.
It looks like Eclipse is not working on threadX at this time.
