Xilinx ZynqUS: Can U-boot do a boot through to another boot.bin ? ( Or other suggestions?)

Jump to solution

Hi Xilinx 

I want to boot from QSPI, load a basic configuration (PL and Basic U-boot device tree) and then stop at the Uboot command line. 

There I like to have a choice with multiple boot options.  For instance: Boot from Emmc with the full blown version of out FPGA code or do a tftp update, etc...

My question(s): 

Is this possible and how can you make the reboot from within U-boot?

If no: What is the best way to approach this problem? 

 

Thanks in advance. 

 

Note: The Emmc also meant to have a Uboot in it's schematics, but you get the idea.

Hi @stephenm 

As an addendum to this post;  Is it possible to restart or reboot the Zynqmp, even with the PMU already running?  

This would make my original question a valiable path to explore: Startup from QSPI and in a later stage boot through to the emmc or the SD card for example.
