Petalinux 2020 BSP for the Ultra96-v2 development board

This PetaLinux 2020.1 BSP for the Ultra96-V2, as well as others for the UltraZed and Zed SOMs and SBCs, have been submitted for posting online, but that sometimes takes a long time.  In the meantime it can be downloaded from here (this link expires on 11/30/2020):

Great! I am downloading it now and will go through the whole petalinux thing with it and report any issues I find.

Thanks very much for the help Tom!

hmmm... it seems to have gone a little further this time. I put BSCAN-JTAG hardware, a debug_bridge device-tree entry and an xvcserver.c app in there. Still crashing after the AMBA setup though.

I can see from the early UART output that it has loaded the device-tree. However, I cannot see anything indicating that it has written the bitstream or configured the PL or PS at all. I assume this means that the kernel panic is not caused by the Vivado generated bitstream I have indicated on the petalinux-package command with the --fpga switch. However, I see form the XSA sysdef.xml that the psu_init.c PS setup C code is labelled PS_FSBL_INIT which implies to me that it is actually part of the FSBL. That makes sense to me now as of course the system will want to do this early on say, for example, to provide infrastructure for the XVC. However, as my previous post shows, the systems halts even without any psu_init.c or bitstream. Clearly I have no idea what I am doing. Again I have read 2 books so far and am reading the Documentation in the tool that Xilinx provides. I hope 1 day to know what I am doing although it might take all the fun out of it.

Thanks

Let me know if I should include any other logs or system details.

I have also added the following in to the system-conf.dtsi but still get the same problem:

&amba {
     zyxclmm_drm {
          compatible = "xlnx,zocl";
          status = "okay";
          interrupt-parent = <&axi_intc_0>;

                    <4  4>, <5  4>, <6  4>, <7  4>,

};

};

Were you able to resolve this? Make sure you are using the correct tag when pulling from github. You can see those for 2020.1 here:
