My best answer to this question:
Unfortunately, this new version does not work yet (even for MilkV) and then it will take Sipeed time to get these advancements available for LicheeRV Nano.
The driver sources can also be found on the chip vendors git: https://github.com/sophgo/osdrv/tree/sg200x-dev/interdrv/v2/cvi_vc_drv https://github.com/sophgo/osdrv/tree/sg200x-dev/interdrv/v2/jpeg I already successfully integrated them into LicheeRV Nano Build but need to test them before I can say if they work. Did you test the drivers yourself or do you have a link which describes the problem?
Thank you so much for your response! I will give them a try.
For some context, I am looking to synchronize multiple LicheeRV Nano cameras together (as best as I could) to record volumetric videos, and that requires a little more tight control over what happens in the camera path.
Here is the result of my work: https://github.com/sipeed/LicheeRV-Nano-Build/pull/45 It is backward compatible to existing projects. I successfully tested it with NanoKVM lite and full. Next step is testing it with LicheeRV Nano W(E) and camera module if it arrives.
I tested it now with gc4653 camera module on LicheeRV Nano W(E). I reverted some changes and kept only the source of cvi_vc_drv and jpeg itself and minimal header changes.
I could not find any rtsp demo/sample that works with gc4653, the samples from the current unmodified image did not work.
So I decided to replace pre-built middleware/v2/sample/test_mmf/libmaix_mmf.a with the code found here: https://github.com/sipeed/LicheeRV-Nano-Build/blob/20240515/middleware/v2/sample/test_mmf/sophgo_middleware.c The older version can also be found here: https://github.com/sipeed/MaixCDK/blob/main/components/3rd_party/sophgo-middleware/sophgo-middleware/v2/sample/vio/sophgo_middleware.c The enhanced cpp version is also based on this: https://github.com/sipeed/MaixCDK/tree/main/components/maixcam_lib
There are three places with hardcoded pixel format, I needed to change it to NV21 for gc4653: https://github.com/scpcom/LicheeRV-Nano-Build/commit/20ae1a99def5e1cd1c305c6391323adc4ff8eeac
The updated samples are here: https://github.com/scpcom/LicheeRV-Nano-Build/tree/middleware-maix_mmf camera to jpg file (working headless): /mnt/system/usr/bin/test_mmf 4 camera to h265 rtsp (working headless): /mnt/system/usr/bin/test_mmf 10 camera to h265 rtsp and vo (works only with oled attached, crashes the whole system if not): /mnt/system/usr/bin/test_mmf 12
All together here: https://github.com/scpcom/LicheeRV-Nano-Build/tree/develop
Thank you, @scpcom! I confirm that I can build an image using your repository (https://github.com/scpcom/LicheeRV-Nano-Build/tree/develop) and it boots.
Unfortunately, RNDIS is broken recently (last time it worked was around https://github.com/sipeed/LicheeRV-Nano-Build/commit/378a06730f37ed319eccc09bc748c96683cdd275), and I don't currently have a USB-Serial dongle around. Once I have it, I will try to connect through the serial console and check if everything (modulo RNDIS) is working.
Thanks again for working on this!
Hi LicheeRV Nano team,
thank you for working on supporting this great board!
I am currently trying to get a camera-based solution developed on LicheeRV Nano, and I need to debug kernel modules, in particular, soph_jpeg.ko. Unfortunately, it's only included in the binary form in this repository: https://github.com/sipeed/LicheeRV-Nano-Build/tree/main/osdrv/interdrv/v2/jpeg/phobos_riscv
Can you please provide a link to the sources for this kernel module and the instruction to build it?
Thank you in advance!
