Would it be possible to do basic OS Dev exercises on the CMM2? I'm not talking about porting Linux or compilers or anything like that. I was thinking something more like writing C code that would display a single character in the upper left hand corner. Would this be possible with the CMM2 Gen2 v2? I'm assuming I could do this using the STM32 dev environment for Linux. I'd probably need external hardware for debugging. I've looked around for these, but I'm not sure which to buy and I definitely don't want to buy the wrong thing. I would be very grateful for any advice at all (even trying to talk me out of it).

Thanks

Are you thinking about a new bare-metal development using the CMM2 hardware as a base?

The simple debugger you would need is a ST-LINK. If you have any of the STM32 Nucleo dev boards these have an ST-LINK built onto them and this can be used to connect to the header on ISCP header on the G2. Alternatively you can purchase a stand-alone st-link V2 or V3 would both work

Yes. I definitely want to look into bare-metal development using the CMM2 hardware.

Your suggestion of buying a Nucleo board is an excellent idea as I could get some "basic training" first and then move over to the CMM2 once I've learned a thing or two about playing with the STM32 platform.

Thanks so much for the response Peter!
