After “zypper dap” command, U-Boot Starts from SD, but USB scanning fails to detect USB carry SSD disk.Then don’t find device to boot from SSD and boot fails.

post upgrade Grub menu list are 6.9 and 6.11 but U-Boot can’t see usb/SSD.
I try to probe USB port and I can see a pendrive normally.
My hardware is Raspberry 3B+.

thanks in advance

Solved, my SSD needs delay, about 5 ms to start. You have to add this delay to U-boot in uboot.env file in SD card.
CONFIG_PREBOOT=“setenv usb_pgood_delay 4000; usb start”

In U-Boot shell type this:

setenv usb_pgood_delay 4000; → delay in ms
saveenv → command to save the changes persistently in file in SD card.

reboot and SDD usb disk now is started in Uboot to do chroot.
