Hi Sascha! > Nice to hear from you here ;)

Is > there some AT91Bootstrap required? Yes. There is a bootstrap required: https://github.com/linux4sam/at91bootstrap However, an old version is needed. I am still fighting the details. I accidently erased it, so my journey for unbricking the device began. at91bootstrap, openocd, barebox - they all once supported A9G20, but nowadays all of them were broken. Well, I fixed openocd and barebox mostly so far, the bootstrap is still the missing piece. Super interesting about the A9263 setup code. I missed it so far. Does that mean that barebox can replace the at91bootstrap? > Anyway, what's really missing is DT support. I scribbled a patch to get > you started in case you are motivated. Basically it's: Compile in the Motivated? No way ;) Obliged? More so. But first, I want to unbrick my device. First make it work, then make it beautiful. That being said, the two patches from this series are okay? I'd think they are still needed for other legacy systems even if I convert A9G20 to DT in some ages. Thanks for your help! Wolfram
