JTAG Debug on ZCU-102

Jump to solution

We have an application running on a ZCU-102 that boots from SD card.  The FPGA part of the load has several ILAs.  I would like to debug the PL/PS interaction with these ILAs.  If we boot from SD card with the JTAG plugged in, the application does not fully load and the PL is not loaded.  If we boot without the JTAG plugged in, then plug in JTAG, the PL part seems to go back to default and I don't see the ILAs in HW Manager.  How can I debug this thing?

Re: JTAG Debug on ZCU-102

If you've compiled the Linux kernel with the FPGA Manager option, you should be able to download an new PL image via command line over SSH (or UART console).   On the other hand, this does complicate the whole issue of device drivers, since they have to be loaded via modprobe after the PL is initialized.

 

If you are running bare metal, this doesn't help, of course, and you might want to debug the reasons why connection of the JTAG prevents your design from loading via the SD card.

 

Does this TCL script help at all?

I'm marking this as solved.  The software engineer on this project did something to his boot code, which is probably equivalent to this.
