Zynq Ultrascale+ Linux Hangs with JTAG connected

Jump to solution

I have Linux booting from SD card on a custom Zynq Ultrascale+ PCB. Linux boots fine without JTAG connected, but if open the Vivado hardware manger and connect a Xilinx platform cable II, linux hangs on boot with the message:

 

"XPFW: DAP RPU WAKE.. DONE"

 

So it looks like it's related to the platform management unit, since this message originates from the pmufw (https://github.com/Xilinx/embeddedsw/blob/master/lib/sw_apps/zynqmp_pmufw/src/xpfw_mod_dap.c), but I'm not sure how to debug further. Any suggestions?
