Why unset, who is setting in the first place?
Ok this might be unnecessary. Could be removed.
- $ export OPTEE_PLATFORM=k3-am62x
None of the addresses OPTEE cares about changed from AM62?
Nope. We have been carrying the same OPTEE flavour since AM62 in AM62A, AM62P and now in J722S
Yocto machine configurations:
AM62A: https://git.ti.com/cgit/arago-project/meta-ti/tree/meta-ti-bsp/conf/machine/include/am62axx.inc#n18 AM62P: https://git.ti.com/cgit/arago-project/meta-ti/tree/meta-ti-bsp/conf/machine/include/am62pxx.inc#n15 J722S: https://git.ti.com/cgit/arago-project/meta-ti/tree/meta-ti-bsp/conf/machine/include/j722s.inc#n15
- $ export OPTEE_EXTRA_ARGS="CFG_WITH_SOFTWARE_PRNG=y"
Do you still need this, the HW RNG should work now.
Yes. We still need SW RNG.
Warm Regards, -Jayesh
