Custom installed ARMtix on RPi4. Stuck on U-boot.

Like the title says. Now it's u-boot that I'm stuck on.



The boot folder is a bit messy though. Maybe I would need to delete some of it,
but I don't know what.

This post is marked as Solved but I don't see how this is solved. I had problems with stock boot.txt so I replaced it with my own:
Code: [Select]
setenv bootargs root=[your root path] rw rootwait console=serial0,115200 console=tty1 fsck.repair=yes
load ${devtype} ${devnum}:${bootpart} ${kernel_addr_r} /[Your image file]
load ${devtype} ${devnum}:${bootpart} ${ramdisk_addr_r} /[Your initial ramdisk uimg]
booti ${kernel_addr_r} ${ramdisk_addr_r}:${filesize} ${fdt_addr}

Remember to set image file path for first load and set correct root path in bootargs and generate new boot.scr with ./mkscr command.

You're right. it hasn't been solved. I changed the title accordingly. 
 
I tried your solution, but that didn't make any difference, 
apart from Working FDT set to 2eff2000.

What if you add `load {devtype} ${devnum}:${bootpart} ${fdt_addr_r} /path/to/dtb` before booti in boot.txt? I don't know how is fdt set without explicitly specifying this command
