Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

RISC-V Ox64 BL808 SBC: Starting Apache NuttX Real-Time Operating System
I bought a bunch of the 16Mbit flash variant for an embedded project but sadly it looks like the firmware always gets corrupted on write, and have gotten no reply from Bouffalo

BL616 SWGPIO driver
I tried looking through the source code of the SDK to get somewhat of an understanding, but it's taking too long for me to understand, so I'll leave it in your hands. gpio.h gpio.c gpio_reg.h

$5 Ai-M62-12F-Kit RISC-V development board features BL616 WiFi 6, BLE 5.2, and Zigbee MCU, plenty of I/Os - CNX Software
BouffaloLab has recently started bringing order to the chaos. They have created a new bouffalo_sdk where they're merging bl_mcu_sdk and bl_iot_sdk, the latter being the one to use for wireless. The README file lists which peripherals are currently supported. There's still work to be done, but it's good news they engaged into this endeavour.
- Use SIMD from C
- Use windows machine remotely to compile.

Ask HN: Project ideas for a Linux kernel module
The chip has complete-ish sdk here(https://github.com/bouffalolab/bouffalo_sdk) we use as "documentation". Datasheet and the reference manual are incomplete.

USB-OTG HID to UART?
I don't think there is a "common solution". From my point of view, the Bouffalo Labs chipsets are not yet widely in use, at least not outside of china. However - as far as I can see, the USB host example code from the SDK interfaces the USB HID parts of the stack, too: https://github.com/bouffalolab/bl_mcu_sdk/blob/master/examples/peripherals/usbhost/usb_host.c

I got my Sipeed M1S Dock (BL808) yesterday, but I don’t see a macos toolchain for the C SDK. Am I missing something?
I just scoured the current main branch of https://github.com/bouffalolab/bl_mcu_sdk and can see the current HAL supports DMA, EMAC, flash, GPIO, MJPEG, PWM, RTC, encryption, timers, UART and USB. DAC and ADC's (audio) are implemented but not tested. I can also see there are BSPs for the LP core if you wanted to take advantage of it, with helloworld examples for all three, and finally there are some examples of using TensorFlowLite in the examples directory that you could build and try too.

SiPeed M0S with Boufallo Lab BL616 RISC-V MCU
Wifi/RF on bl616 is the same state as bl808. We are waiting for bouffalo to release support for it in bl_mcu_sdk: https://github.com/bouffalolab/bl_mcu_sdk/issues/85

riscv64 is now an official Debian architecture (rebootstrap in progress)
I thought I had read somewhere that the Packed SIMD (P) extension was still going to be developed for implementations that don't need the full-blown Vector (V) extension, for example, embedded processors for digital signal processing.
