nuclei-sdk

1 48 9.1 C

Nuclei RISC-V Software Development Kit

Project mention: Help with PlatformIO and Longan Nano | reddit.com/r/embedded | 2021-03-31

I don't use the Nuclei Studio IDE but I can also vouch for the Nuclei SDK. I did a write up about different ways of flashing the Longan Nano a while ago. Maybe it can help you debug the PIO flashing problem.

My QEMU fork with pinning (affinity) support and a few tweaks.

Project mention: What is the iothreadpin and emulatorpin equivalent for QEMU without libvirt? | reddit.com/r/VFIO | 2021-08-22

I found qemu-pinning for CPU pinning using QEMU without libvirt. I'd like to know, if there's an equivalence for emulator and iothread pinning.
