Hello Michael,
By the way, where's the best source of information about the Sophgo sg2000 and sg2002 processors? Even the Sophgo website doesn't seem to have them :-/ . It just mentions the CV18xx ones.
The best source of information I found for the Sophgo SG2002 and SG200 is this Github repository from Sophgo :
https://github.com/sophgo/sophgo-docIt contains the Technical Reference Manual for the Sophgo SG2000, SG2002 and SG2042.
