Hello!
I have updated my genode-rockchip to include RK3399. Unfortunately none of the targets starts using Genode from git. They doesn't survive the jump from bootstrap/ctr0 to bootstrap/init.

Short follow up. It seems to be mandatory with a size specification in mmio mapped registers. I don’t know but the uart might fail. I misinterpreted it in video driver, while change it.
If someone can take a look if would help. The uart is strictly based on imx uart so copied the size from that.

And now I know more about where it fails https://github.com/mickenx/genode-rockchip/blob/main/src/bootstrap/board/rk3... I have dumped the debug versions and found that it is in one of the mem regions that fails.
I don't understand why. I have compared to the iMX repo and it is done similar. As for RAM , I have tried to give it less ram .. but it should work .. board has ram from (top of uboot) to 4GB.
I guess someone can see directly what the problem is :-)

I wonder why you use an exact copy of the i.MX specific UART driver for the Rockchip UART. Are they really identical with respect to their programming interface? Just curious about it.
And now I know more about where it fails https://github.com/mickenx/genode-rockchip/blob/main/src/bootstrap/board/rk3... I have dumped the debug versions and found that it is in one of the mem regions that fails.
I wonder why this specific line should be the problem. Those regions are only static arrays of memory region descriptions. No one of these memory regions is touched at this point, but later. In contrast, below in the constructor body the Pic aka Gicv3 gets initialized for the first time.
Are you really sure with your analysis regarding the memory regions are the problem? How did you found it, by printing, or some other debug mechanism?

I checked trace from u-boot and compared it with objdump output. It seemed like crashing in board constructor. But I have been proven wrong before :-)

It is a mmu problem. If I skip disable_mmu in crt0.s run/log completes successfully. Not sure why this happens. That is probably why it crashed in Board constructor

This is the contents of sctlr_el2 0000000030c51835 ( starting at EL2 now) I provoke a crash, branch to 0x0, after mrs, and the register dump gives that value in x8.
Starting with EL3 gives the same symptom.
