uboot + rpi2 = no usb at all!

by **qaron** » Sun Nov 13, 2022 11:30 am

i've been thinking how should i boot my rpi2 from usb... and i found a way but its not working and i cant figure out what to do next.
steps to reproduce:
1. format the mmc card and follow this guide: https://www.beyondlogic.org/compiling-u-boot-with-device-tree-support-for-the-raspberry-pi/
2. format my usb external drive as a single partition and flash the image with this: $this->bbcode_second_pass_code('', 'bsdtar -xpf ArchLinuxARM-rpi-armv7-latest.tar.gz -C root')
$this->bbcode_second_pass_code('', 'U-Boot> part list usb 0
Partition Map for USB device 0 -- Partition Type: DOS
Part Start Sector Num Sectors UUID Type
1 2048 234439598 00837ee5-01 83

U-Boot> part list mmc 0
Partition Map for MMC device 0 -- Partition Type: DOS
Part Start Sector Num Sectors UUID Type
1 2048 61118464 02930e5b-01 0c
')
3. add a file in the mmc boot.txt:
$this->bbcode_second_pass_code('', '
setenv kernel kernel7.img
setenv initramfs initramfs-linux.img
setenv bootargs root=/dev/sda1 rw rootwait rootfstype=ext4 rootdelay=60 smsc95xx.macaddr="${usbethaddr}"
if load usb 0:1 ${kernel_addr_r} /boot/${kernel}; then
if load usb 0:1 ${fdt_addr_r} /boot/${fdtfile}; then
if load usb 0:1 ${ramdisk_addr_r} /boot/${initramfs}; then
bootz ${kernel_addr_r} ${ramdisk_addr_r}:${filesize} ${fdt_addr_r};
else
bootz ${kernel_addr_r} - ${fdt_addr_r};
fi;
fi;
fi')
create the boot.scr to enable autoboot on uboot!
$this->bbcode_second_pass_code('', 'sudo mkimage -C none -A arm -T script -d boot.txt boot.scr')
add inside the config.txt:
$this->bbcode_second_pass_code('', 'kernel=uboot.bin')

start the boot process - uboot boot time:
$this->bbcode_second_pass_code('', 'U-Boot 2022.10 (Nov 10 2022 - 15:08:19 +0000)

does anyone has any ideas?? it's working if you boot from mmc. the whole point is that you load uboot from mmc and inside uboot environment you could load the files from usb device!!! if all goes well you boot technically from usb, write to usb and you avoid flash degradation from read/writes.
thank you in advance!!

uboot + rpi2 = no usb at all!

uboot + rpi2 = no usb at all!
