06:48 <dsimic> Dex2x: the A2-rated microSD cards I ordered should arrive today :)

10:53 <rgolledge> Hi just got upstream atf and optee-os running on my rk3566 my next part is to write the Hardware Uninque Key. Is there any documentation about the OTP and the secure OTP i am guessing someone has lookd at this before

10:57 <qschulz> rgolledge: I don't think optee-os currently supports rk3566/rk3568, c.f. https://github.com/OP-TEE/optee_os/pull/6954 so please don't keep this to yourself and help those people out :)

11:19 <Dex2x> dsimic, nice which did you get? This lenovo one I got, is pretty slow, but the xiaomi one seems fine, did a 0 of the whole thing got an avg of 14-22MB/s and seems to boot snappy

11:20 <Dex2x> also so called high endurance

12:05 <rgolledge> qschulz: both my company and the client are more than happy to upstream the optee port. I have it working and can use trusted keys linux, just need to add the HUK not the dummy function i have. There is a some code for rk3588 around this but i am unsure how different the it is from my chip

12:23 <a3f> rgolledge, i recall the rk3566 RNG is not good, see kernel mailing lists. You'll have to account for that if you generate the HUK on-device and write it
