Re: FreeBSD on milk-v duo with CV1800B SOC

 Hi Ruslan,

Thanks for your response.

Is there an image that we can put on a SD card and try? Or instructions to build the latest code that might work?


thanks,
Sreenath

 Hi Sreenath,

The work for C906 is in progress. There are plenty chinese chips with c906 core available (e.g. Allwinner D1, ArtInChip D21x, Cvitek etc) so we would like eventually to have some support for them.
Note there are newer C907 and C908, example Kendryte K230 with AI accelerator which might be similar in terms of support needed (?). Main issue is that these T-Head cores implement non-standard extensions like non-standard control status registers (e.g. mxstatus), page table entry bits and a cache management subsystem.
