If no sources available for rk3566, it would be disappointing: the chain of trust really depends on trusting RockChip's TF-A binaries, not the solution builder. Also, the Linux part of the userland OP-TEE cannot be built. I wanted to evaluate signed and encrypted boot, which then I cannot.
Does anyone have any comments on this? Will Rockchip ever release these sources? When if so?
Rockchip has not yet released the trusted firmware source. We've been told that they will do this in due time, once they've cleaned them up. The plan is to release them eventually, from what we know. It's just not a priority for them right now.
Thank you @CounterPillow , it helps know the perspective.
What remains is getting specifics about the JTAG/SWD on Quartz64 board: Which of JTAG or SWD is used? Where are these exposed on the board? And any other specifics such as OpenOCD config that can help setup the debug environment? Where could I find this info? The RK3566 datasheet does not seem to provide specifics. There is some mention on the Quartz64 schematics, but it isn't exactly clear.
