ChibiOS Free Embedded RTOS

That's great news to hear!

With regards to the multi core communication, the cores are interconnected through 2 FIFOs, writing to the FIFO from one core can raise an interrupt on the other core.

See section 2.3.1.4. Inter-processor FIFOs (Mailboxes)


...
Each FIFO is 32 bits wide, and eight ...

Did you open any PR there?

Debugging with SWD should be definitely possible and even encouraged to upload the firmware.

The official docs mention plugging the SWD port from the Pico into UART on another Pico or Raspberry Pi computer.

Also, a custom OpenOCD build might be needed.

See section 5. of https://datasheets.raspberrypi.org/pico ... h-pico.pdf
https://github.com/raspberrypi/openocd

Now next step is: how to load code in those?


You should be able to connect the device as a USB Mass Storage and just drop UF2 firmware onto it.

All documentations can be found on this site: m
- RP2040 datasheet
- Pico datasheet
- Getting Started guides with the board and SDK

This is the ...

I have also ordered a piece, I'm very excited.

Raspberry Pi Pico has been just released with Dual-core Arm Cortex M0+ processor at 133 MHz and some interesting features like inter-core FIFOs and Hardware Spinlocks.

From hobbyist perspective, I think it would be very interesting to get ChibiOS running on this device.

Hello guys,

I finally discovered what was wrong The program was fine, the problem was with the way how I flashed it and executed it. I used the BOOT pins to select the internal bootloader, then I uploaded the hex file over uart using the stm32flash utility and then I instructed the utitility to ...

Hi,

1) since I don't know how to enable it, I assume it's disabled Now seriously, the chip works with other projects without Chibios and when I remove all references to chThdSleepMilliseconds() from the code and rise the priority of the blink thread, it keeps running with LED 50% duty cycle.
2) A ...

Hello everyone,

I have a board with the STM32F103C8T6 mcu from ebay, it can be found for $3 as STM32 minimum system board, it's basically a clone of Maple Mini. I have been trying for two days but I can't get it working. It's working fine with the standard peripheral library provided by ST, but ...
