Like some command about it

Skip reason why i have uboot, but can i have tutorial about how to boot armbian from usb by uboot?

ok but this is about bootloader

my build is 5.15 by ophub

so now my uboot is in my sd card according to some instructions and I still can't boot into uboot directly

i found some uboot commands here but i don't understand: setenv bootcmd 'run mytvboot; if test ${bootfromnand} = 1; then setenv bootfromnand 0; saveenv; else run bootfromsd; run bootfromusb; run bootfromemmc; fi; run storeboot' setenv mytvboot "run boot_usb; run boot_mmc; run boot_emmc;" setenv boot_usb 'usb start; for usbdev in 3 2 1 0; do if fatload usb ${usbdev} 1000000 u-boot.ext; then go 1000000; fi; if fatload usb ${usbdev} 1000000 s905_autoscript; then autoscr 1000000; fi; done' setenv boot_mmc 'for mmcdev in 0 1 2; do if fatload mmc ${mmcdev} 1000000 u-boot.ext; then go 1000000; fi; if fatload mmc ${mmcdev} 1000000 s905_autoscript; then autoscr 1000000; fi; done' setenv boot_emmc 'for mmcdev in 0 1 2; do if fatload mmc ${mmcdev} 1000000 u-boot.emmc; then go 1000000; fi; if fatload mmc ${mmcdev} 1000000 s905_autoscript; then autoscr 1000000; fi; done' setenv upgrade_step "0" saveenv

can change default boot to sd card. because i already run armbian using sd card
