RP2350 support
RP2040 successor : https://dmitry.gr/?r=06.%20Thoughts&proj=11.%20RP2350
- 2x Cortex-M33F
- improved DMA
- more and improved PIO
- external PSRAM support
- variants with internal flash (2MB) and 80 pins (!)
- 512KiB ram (double)
- some RISC-V cores? Low power maybe?
That's really interesting! I haven't looked much into any of the new Cortex M33 chips since all the CMSIS stuff is Apache 2 licensed. I wonder if anyone has clean-room made their own. Seems like an enormous task.
Too bad there wasn't a Pi Pico with a Cortex M4 and tons of RAM. Would be excellent.
I could do what a lot of other projects do and just git submodule the CMSIS and HAL stuff, but I would like the OS to be as self-contained as possible. I'll keep thinking about this..
