RP2350 Partitions
Description
As the new RP2350 chip now supports partition tables (5.1.2 in the datasheet) and writing to them for A/B versioning and more, this should be supported by micropython.
It could be implemented like the ESP32 Partitions and probably should be for feature parity.
Code Size
Not sure, but putting it behind a compiler toggle sure wouldn't hurt. But since the Pico has plenty of storage anyway, it could also just be enabled by default.
Implementation
I hope the MicroPython maintainers or community will implement this feature, I intend to implement this feature and would submit a Pull Request if desirable
Code of Conduct
Yes, I agree
HSTX Support for RP2350
Description
Would love for the RP2350's HSTX peripheral to be available in MicroPython! It provides an interface for outputting data ludicrously fast (8 GPIO pins (GPIO 12-19 only), DDR on each clock cycle, so up to 2.4Gbps without any overclocking), very useful for things like displays. Would be a part of the rp2 module, only on RP2350 boards (not supported on RP2040).
Section 12.11 of the RP2350 datasheet provides more details about the hardware. There are also a couple examples from the pico-examples repo.
As I understand it, basically just need to gpio_set_function(<GPIO 12-19>, GPIO_FUNC_HSTX), configure the hardware peripheral hstx_ctrl_hw (from hardware/structs/hstx_ctrl.h using macros from hardware/regs/hstx_ctrl.h), then send data to the FIFO buffer hstx_fifo_hw (from hardware/structs/hstx_fifo.h using macros from hardware/regs/hstx_fifo.h). I believe it's also possible to have the DMA feed the HSTX FIFO, DREQ_HSTX is a member of the DMA's dreq_num_rp2350, which should be made available in MicroPython.
Code Size
IMO this should always be enabled for RP2350 boards as part of the rp2 module, similar to the PIO and DMA features. Not expecting it to be very large.
Implementation
I hope the MicroPython maintainers or community will implement this feature
