Pi4 not booting from usb

[DerTeufel]

maybe i missed something somewhere...i have pi4b running latest official retropie image, installed through imager application, on sdcard.
I did update everything to latest available packages today, did a backup of the sdcard, and then wanted to try boot the pi from usb (while not removing the sdcard).
from what i understand, this should be supported meanwhile....

still it always boots from sdcard

vcgencmd bootloader_config
[all]
BOOT_UART=0
WAKE_ON_GPIO=1
POWER_OFF_ON_HALT=0
BOOT_ORDER=0xf14

Your boot order is SD-Card, then USB, codified as f14 and shown on the bootloader screen. If you wish to boot from USB first, then change the order to f41. You can find more details in the EEPROM configuration doc page, including on how to change the configuration.

@mitu thx...there seems to be some misleading information on the page you linked...and i seem to have picked the wrong info...

0x4 USB-MSD USB mass storage boot - See USB mass storage boot

BOOT_ORDER Description
0xf41 Try SD first, followed by USB-MSD then repeat (default if BOOT_ORDER is empty)

0xf14 Try USB first, followed by SD then repeat

funnily, i had (tried to) changed it from gui...and selected the option: boot from usb, fallback to sdcard...

let me try changing it to 0xf41... i'll report back

edit: I changed it:
rpi-eeprom-config
[all]
BOOT_UART=0
WAKE_ON_GPIO=1
POWER_OFF_ON_HALT=0
BOOT_ORDER=0xf41

and now i don't even see the bootloader screen anymore...instead it directly boots retropie from sdcard

edit2: 0xf14 is the correct mode... problem is not with retropie nor with the config.
I now have tested an usb-stick with recalbox, and it boots just fine... previously i tried to boot lakka 64bit from usb, which did/does not work.
I guess i need to check lakka forum for support...
