Hello Alex and thank you.
You assumption is correct, I am on a non-supported platform (the Trenz
ZynqBerry). So probably some tweaks will be needed.
Do you suspect that I will need to make these changes in the sel4 code or
will finding and changing some configuration file be enough?
First, of course, I need to figure out what the important differences
between the ZC706 and the ZynqBerry are.
I was using the release build but now switched to debug and tried that as
well. That did not produce any additional output.
So that UART configuration changes are needed sound very likely.
Thanks again and have a great day

Hi Joel,
Which Zynq-7000 platform are you using? The supported platform is the ZC706. Other platforms might need some trivial changes, particularly for UART baudrate configuration.
Are you using the debug or release config? The debug build should show additional messages during boot.

Hello,
I want to learn about seL4 so I am trying to get is started on the hardware I already have (a zynq 7000).
I have generated the image: sel4test-driver-image-arm-zynq7000
Now I try to load that onto the zynq by executing these commands in XMD: connect arm hw rst fpga -f design_1_wrapper.bit source ps7_init.tcl ps7_init ps7_post_config dow sel4test-driver-image-arm-zynq7000 run
All of the above seem to be successful. Then, I have a serial link hooked up to the board (uart) and there I get the following output (screen /dev/ttyUSB1 115200) : ELF-loader started on CPU: ARM Ltd. Cortex-A9 r3p0 paddr=[10000000..103c881f] ELF-loading image 'kernel' paddr=[0..2afff] vaddr=[e0000000..e002afff] virt_entry=e0000000
But then nothing more. I am lost what to do from this position in order to continue exploring seL4. I don't even know if what I see is an indication of a problem or not. If anyone has experience in running seL4 on zynq and if you sit on knowledge you want to share, please fill me in.
Thank you
