Thanks for the tip! I'll check with the folks who added Nim support to NuttX, and figure out whether we should call GC_runOrc()

Thank you so much! 2024 will be an awesome year for 64-bit RISC-V Gadgets (like Ox64), I'll write lots more :-)

Thanks! Yep we should do more Nim programming on microcontrollers, since they have lots more RAM nowadays.

Thanks! I'm still having problems with UART Interrupts and PLIC. Hopefully I can rethink what I wrote, and figure out the solution :-)

Bouffalo Lab seems to be rolling out a new SDK that supports BL602 and BL808: BouffaloSDK https://github.com/bouffalolab/bouffalo_sdk Ox64 won't work with MIPI DSI Displays, because it runs on BL808C (instead of B

Yep I agree, programming the 64-bit and 32-bit RISC-V Cores in BL808 SoC can be really challenging! I hope to run NuttX RTOS on both cores, talking over OpenAMP.

Thanks! The JH7110 Display Controller is super complex, it might take a while to get it working with NuttX. Right now I'm building the I2C Driver for JH7110, which is needed to power up the PMIC for HDMI Output: https://gith
