SDCard image does not boot on bpi-r4 #16

Both the image from the latest release here and one I built myself (for added EFI support, but I also tried building a vanilla one) just fail to boot with:

System halt!

If I flash an sdcard image from the openwrt snapshots (https://firmware-selector.openwrt.org/?version=SNAPSHOT&target=mediatek%2Ffilogic&id=bananapi_bpi-r4), the system boots just fine. So I'm pretty confident the SD card, the hardware and my method of writing the image is okay.

Are you sure you used the right file (which one exactly)? Have not changed atf/image part for long time and not even bl2 can be loaded

Found the issue. I ended up with two solid files, /dev/loop0p1 and /dev/loop0p4 in place of the correct dev nodes. So those two files never made it to the SD card, since losetup did not replace them. After deleting them and re-running createimg, it works fine.

I'm not sure why the downloaded image didn't work fine. Maybe it failed to flash correctly, due to the substantially larger size (I shrunk mine down to 250MB)
