Arty-Z7 20 - Petalinux QSPI boot

[toddsharpe]

I've got an arty z7 that I've got booting petalinux with SD and jtag booting. However, I'm having trouble getting it to qspi boot, or more specifically getting the boot+kernel image petalinux builds to fit on 16MB qspi. Seems a default Petalinux is about 16MB kernel and 5MB Boot.bin, I've tried shaving my image down, its currently 10.3MB image.ub and 5.2mb boot.bin so I guess it should barely fit? I'm following the steps at: https://docs.xilinx.com/r/2021.2-English/ug1144-petalinux-tools-reference-guide/Steps-to-Boot-a-PetaLinux-Image-on-Hardware-with-QSPI-or-OSPI but this doesn't leave room for boot.scr. Has anybody done this successfully?

Curious your petalinux config/uboot steps to program flash.

Another hint something isn't working - typing those sf commands and rebooting arty-z7 doesn't seem to remove the demo blinky app from arty-z7 (after selecting qspi boot).

Hi @toddsharpe

does writing BOOT.BIN at the begging of QSPI boots into u-boot ? when qspi jumper is set?

u-boot loads boot.scr and loads image.ub according to instructions in boot.scr
if boot.scr has a wrong address for image.ub(is a FIT) the entire process fails.

 

According to
https://docs.xilinx.com/r/2021.2-English/ug1144-petalinux-tools-reference-guide/Configuring-U-Boot-Boot-Script-boot.scr

expected boot.scr address is 0xFC0000
