DiscoBSD on Pyra's M4 ?

[Magic Sam]

Hi all,

I stumbled on this project some days ago:

GitHub - chettrick/discobsd: 2.11BSD-based UNIX-like OS for STM32 and PIC32 Microcontrollers

2.11BSD-based UNIX-like OS for STM32 and PIC32 Microcontrollers - GitHub - chettrick/discobsd: 2.11BSD-based UNIX-like OS for STM32 and PIC32 Microcontrollers

github.com

This microcontroller-focused operating system is the continuation of RetroBSD, a 2.11BSD-based OS targeting only the MIPS-based PIC32MX7. DiscoBSD is multi-platform, as it also supports Arm Cortex-M4 STM32F4 devices.

Do you think it'd be possible to make it run on the Pyra's M4 CPU ?

Cheers, Magic Sam

It's certainly possible, but it would take a bit of porting. Additionally, I don't know how you would get a prompt

Hi @Risca

The README file mentions using the serial port to log into DiscoBSD:

Communication with DiscoBSD requires a serial port. A USB to TTL device or the built-in VCP USB serial port on development boards can be used.

$ cu -l /dev/cuaU0 -s 115200
