To the risc-v folks: I am looking for a mini-board with a 64bits RISC-V core, USB-C (power+data), many(~30) available GPIOs, easy to flash or boot from a memory card. That for a keyboard firmware directly written in 64bits risc-v assembly.
The BL808 is actually a 32bits risc-v as a main core with a 64bits risc-v core on the side (convoluted hardware programming from the 64bits risc-v core).
The K210 does not seem to have a USB controller (only a UART<->USB dongle).
Then I am lurking on some mango boards, with a D1, the D1 being completely overkill.
Anything else?
- AlexeyBrin 4y agoThe soon to be released VisionFive 2 board seems like a good match https://www.starfivetech.com/en/site/boards https://www.starfivetech.com/en/site/boards

- snvzz 4y agoThat's significantly more overkill than the D1.
- sylware 4y agoThe D1 based miniboards seem to be the currently only alternative for what I would like to do. Only the mango pi board I guess, or any others? I could not confirm if the k210 has a usb controller (not the UART<->USB dongle).
- snvzz 4y agoSee the list of boards part of the D1 article[0] in linux-sunxi wiki. There are at least 5 options listed. Lichee RV (with a breakout dock board) is the one I have. https://linux-sunxi.org/D1 https://linux-sunxi.org/D1
- sylware 4y agoThanks for the page. I guess I would have to go for the mangopi: usb-c device/power port and the GPIOs.
- trissylegs 4y agoSuper-early bird are out! If shipping is good. I haven't been able to boot mine. But I have no UART adapter to see whats wrong.
