arch/risc-v/rp23xx-riscv: Initial rp23xx(rp2350) (Pico 2) RISC-V support
Summary
Add support for RP2350 RISC-V cores, Add Pico 2 board.
Naming
Chip name : rp23xx-rv
Board name : raspberrypi-pico-2-rv
Arch : risc-v
Changes from ARM rp23xx impl
- Linker script update
- ASM head start
- Update chip start
- New Hazard3 include regs
- Remove rp23xx chip hw spinlocks/testset
- New irq handling (external IRQ interrupt)
- New timerisr based on RISC-V std MTIME and alarm arch
- No SMP yet
- Tickless option
- Double size for idle, irq and main stacks
- Board reset via watchdog trigger ...
Todo
- [x] Uart defconfig
- [x] ostest pass
- [ ] usb defconfig (USB stuck on handshake, no ext interrupt received, same code as ARM works)
- [ ] SMP
- [x] Reset (via watchdog trigger without wd dev)
- [ ] Better IRQ (priorities? nested? )
- [ ] More timers
- [ ] Tickless testing
- [ ] Peripherals testing
- [x] WDOG
- [x] UART
- [ ] USB
- [x] PWM
- [ ] I2C
- [ ] SPI
- [ ] DMA
- [ ] Docs
- [ ] Add chip
- [ ] Add board
- [ ] Toolchain info
- [ ] Other boards
- [x] RISC-V Custom extensions (zba_zbb_zbs_zbkb_zca_zcb_zcmp in defconfig, add to chip?)
- [ ] Compare getprime perf
- [ ] LVGL perf test
Toolchain
Use RISC-V gnu toolchain with soft float abi. Default riscv-collab uses double float abi
This is config for https://github.com/riscv-collab/riscv-gnu-toolchain
./configure --prefix=/opt/riscv --with-arch=rv32imac --with-abi=ilp32
Config
./tools/configure.sh raspberrypi-pico-2-riscv:nsh

Wow! That's great. I love RISC-V. I did not expect this RP23xx RISC-V to come to NuttX. I will be testing this out today as well, thanks!
Hmm, @shtirlic configuration fails and I am not entirely sure what this means. I cloned your branch.

Possibly something to do with the RISCV tool chain I have to install and configure? I did install it into my system using 'yay' from 'AUR'.
Any idea?
Okay manually compiled the toolchain with the correct configuration, but as probably expected, this did not make the nuttx configuration work :thinking:
Okay manually compiled the toolchain with the correct configuration, but as probably expected, this did not make the nuttx configuration work :thinking:
It's just a warning(not sorted out yet) did you try to make it? Yeah toolchain from aur built with double float, that's why we have to build with soft ABI for Arch.
@shtirlic Nice, the warnings are gone!
How do i make this using the custom built toolchain? It's targeting the wrong one.

Not entirely sure how it's finding the toolchain, but i might have to change something to make it find the correct (custom) one.

You should add it to the PATH env something like this
export PATH=/opt/riscv/bin:$PATH
@shtirlic Nice! I confirmed this works perfectly fine with ostest. The serial output also looks consistent.
The problem I had was quite simple. Doing make distclean after changing toolchain path fixed the problem.
@shtirlic I have a suggestion. This could save some big headaches for developers in the future using this config. I suggest increasing the stacksize of nsh_main by changing the default task stacksize. See kconfig below
config INIT_STACKSIZE int "Main thread stack size" default DEFAULT_TASK_STACKSIZE(=2048) help The size of the stack to allocate for the user initialization thread that is started as soon as the OS completes its initialization.
As you can see, default is 2k, which is exceeded after enabling some basic debugging or applications in kconfig. Causing crashes without notice. See image below for stack usage:
This chip has plenty of memory and I consider that few kB of extra memory usage to prevent headaches worth it. 4k should be more than enough.
Update:
changed the chip name to rp23xx-rv and board name to raspberrypi-pico-2-rv to me more consistent
@keever50
29 .. CONFIG_IDLETHREAD_STACKSIZE=2048
30 29 CONFIG_INIT_ENTRYPOINT="nsh_main"
31 .. CONFIG_INIT_STACKSIZE=4096
32 .. CONFIG_IRQ_WORK_STACKSIZE=4096
Remember always do: make distclean before updating the branch

That's perfect thank you!
Hey there @shtirlic great work, keeping my fingers crossed! I have rPI-Pico2 and rPI-Pico2W boards, will test on FreeBSD with system provided toolchain and/or espressif rv32 toolchain that I use to work with ESP32-C3/C6 :-)
Update: Handling multiple external interrupts via Hazard3 interrupt extension i2c working
Update: finally USB is working, from now you can use board USB defconfig. The problem was in code enabling and disabling external interrupts, Hazard3 uses custom interrupt extension (PLIC like) for handling external (devices) interrupts and some custom register arrays for external interrupt enable/force/pending array
3.8.6.1. Xh3irq: Hazard3 interrupt controller
Xh3irq controls up to 512 external interrupts, with up to 16 levels of pre-emption. It is architected as a layer on top of the
standard mip.meip external interrupt line, and all standard RISC-V interrupt behaviour still applies. This extension adds no
new instructions, but does add several CSRs:
• MEIEA: external interrupt enable array
• MEIPA: external interrupt pending array
• MEIFA: external interrupt force array
• MEIPRA: external interrupt priority array
• MEINEXT: get next external interrupt
• MEICONTEXT: external interrupt context register
Xh3irq is geared towards supporting interrupt handlers as bare C functions, with dispatch implemented in software and
pre-emption priority logic implemented in hardware. However, the exact interrupt ABI is up to the implementation of the
soft dispatch routine installed as the mip.meip external interrupt handler.
Excellen work @shtirlic :-) What compiler do you use? Looks like some custom compiler is required?
On FreeBSD 14.2-RELEASE-p3 with default system riscv32-unknown-elf- toolchain I have build errors, and Espressif's riscv32-esp-elf- does not seem to handle required extensions :-P
Configuration is okay:

Yes, rp23xx needs soft float abi gcc compiler in the top of the pull description I provided the configure for riscv toolchain
@keever50: Not entirely sure how it's finding the toolchain, but i might have to change something to make it find the correct (custom) one.
You may also provide crossdev directly as make parameter i.e. make -j24 CROSSDEV=riscv32-esp-elf- and it must be in path :-)
@shtirlic: Yes, rp23xx needs soft float abi gcc compiler in the top of the pull description I provided the configure for riscv toolchain
Tanks @shtirlic! Missed that works now :-) Toolchain built in 5 minutes, nsh and usbnsh builds fine, will test runtime in a free moment :-)

I can see CI has the same problem - not the toolchain required :-)
Do you know @shtirlic if it is possible to build this toolchain with all possible extensions so we can have megacompiler to built them all for CI? :-)
Yes, should be possible, see the https://github.com/riscv-collab/riscv-gnu-toolchain multilib feature
@cederom also please have a look at https://xpack-dev-tools.github.io/riscv-none-elf-gcc-xpack/blog/2024/12/06/riscv-none-elf-gcc-v14-2-0-3-released/
Ah I think @lupyuen uses xpack and recommended to me that one.. there are no official builds for FreeBSD but I may create a port if its worth it :-)
Allright we have new xpack-riscv-none-elf-gcc 14.2.0-3 in the CI (https://github.com/apache/nuttx/pull/16645) lets see how the CI build goes :-)
Just want to say you are doing a great job. I am still looking forward to this. You will make an impact, at least for me. Making the Raspberry Pi Pico a NuttX option again, together with the nice risc-v arch. The USB integration absolutely does it (very flaky in rp2040)
Hmm, still some unknown opcodes.. not a multiarch toolchain package / build, that do you think @lupyuen ? I will setup the lubuntu vm to try out the ci on local machine :-)

Thank you, should be pretty usable in next weeks, with RISC-V version I am getting much longer non interrupted uptime (more than 1 day at current time) on the same apps/config as for ARM (around 2-3 hours), (constant i2c poll driver and LVGL shell)
Hmm, still some unknown opcodes.. not a multiarch toolchain package / build, that do you think @lupyuen ? I will setup the lubuntu vm to try out the ci on local machine :-)
Pushed some changes to defconfig custom extensions flags that should for sure work with gcc14, not enabling all of the possible extensions.
@shtirlic did you see the Olimex rp2350pc: https://www.olimex.com/Products/RaspberryPi/PICO/RP2350pc/open-source-hardware
Seems like an amazing board to run NuttX ;-)
