Hi Michal,
the issue is likely related to incorrect DDR configuration. BSS and Malloc space are in DDR. > rev1.1 has different DDR sodimm module then rev1.0.
Thanks, this never occurred to me as Xilinx says to use rev1.0 software for rev1.1 boards, so that's what I did.
First of all I sent v2 because of dt changes to see 1.1 revision and I have also tested it on real HW.
Yes normally it works like that newer board revision works with previous versions. But 1.1 is different case.
I have generated psu init from vivado 2019.2 for 1.1 revision and send it to mailing list. I didn't test it on hw but please test it and let me know.
I had already done that in the past (feed Vivado 2019.2 psu file into u-boot), with no success. Unfortunately, your patch doesn't help either, the behaviour is still exactly the same as before.
Build it like this. export DEVICE_TREE="zynqmp-zcu102-rev1.1" make xilinx_zynqmp_virt_defconfig make -j
For some reason, that's no enough: I have to manually set CONFIG_DEVICE_TREE because xilinx_zynqmp_virt_defconfig sets it wrong. In any case, behaviour is exactly the same as before.
With latest my queue it should be enough. https://github.com/michalsimek/u-boot/tree/mainline-v20200312
But I think that latest mainline should setup default in ITS properly. You can check it by looking at u-boot.its when build is done and find default configuration option which should point to 1.1 dt.
Here are jtag steps I have run.
Thanks, Michal
