Petalinux 2020.2 PicoZed JTAG Boot Issue

cthomas43
cthomas43 10 months ago

Hello,

 

I am having trouble getting to boot the PicoZed board using JTAG. I have configured the DIP switches appropriately and using "petalinux-boot --jtag --kernel" seems to work as it is able to download the elf files and images at the corresponding addresses. Then checking the UART port, it starts up and then hangs (see attached messages) indicating wrong ramdisk image format.

 

If I boot the same images using an SD card, it works without an issue. Is there something I am missing such as reconfiguring the rootfs location?

 

On a separate point, I was also able to debug the PicoZed over ethernet in Vitis 2020.2, however it recently doesn't launch into the debugger (the connection is there, both host and board can ping each other and test connection is successful, but not able to get into the normal debugger window. It is as if the debugger is not able to stop the CPU, has anyone experienced this before?

 

Many thanks,

 

Chris
