How to boot via SD with hardrware set to QSPI

Jump to solution

Hello

I have a custom board (MPSOC 9EG ,Vivado 2018.3) with QSPI boot configuration with no options to switch boot modes via hardware ( no jumpers )

I would like to program the QSPI with an FSBL that resumes the boot at SD . where should i make  the changes at FSBL ? is it possible ?

what should I program the qspi ? FSBL+PMU+BIT  ? 

afterwards I use Petalinux to build the rest of the boot files. what files should i place over the SD ?

 

Thank you!

You can put pmufw, FSBL, atf, and U-Boot in the QSPI and have U-Boot hand off to Linux in the SD.  Is that what you want to do?   This can be done in PetaLinux and is described in UG1144.

 

I'm not sure what you are wanting to do and what you design constraints are.
