I read in here someone have given the step to customize the kernel of persee:
I have some early persee development board (board with 2 stack pcb, without casing).
Can someone sent me (firstname.lastname@example.org) the source code of the kernel?
Send them an email - that's what we did. Note the Persee development boards are entirely different to the final Persee circuit board - they had to redesign the whole thing after the dev boards were rolled out.
Where should i email? Email for the development team is not shown on the sites.
It's listed here https://orbbec3d.com/contact/
Thats business team and press team. I will email it though. Thanks.
I actually try to upgrade the android to nougat, for its AI feature. I don't know if it is possible. Long way to go i guess.
