Hi,
i'm trying to reactivate my old sabre lite board. It has u-boot on an
internal flash.
I can update it to the u-boot supplied by boundary devices (U-Boot 2018.07).
With that i can boot their Debian 10 image.
I can also boot an openbsd miniroot-nitrogen-67.img miniroot into the
openbsd elf bootloader and it loads a kernel, but then nothing more
happens:

Usage:
load <interface> [<dev[:part]> [<addr> [<filename> [bytes [pos]]]]]
- Load binary file 'filename' from partition 'part' on device
type 'interface' instance 'dev' to address 'addr' in memory.
'bytes' gives the size to load in bytes.
If 'bytes' is 0 or omitted, the file is read until the end.
'pos' gives the file byte position to start reading from.
If 'pos' is 0 or omitted, the file is read from the start.

-----------------------------------------------------------
The 2018 u-boot does not define the variables needed by the 6x_bootscript on
our miniroot.
With
setenv fdtfile imx6q-sabrelite.dtb
setenv fdtaddr ${fdt_addr}
load mmc 0:1 ${fdtaddr} ${fdtfile}
load mmc 0:1 ${loadaddr} efi/boot/bootarm.efi
bootefi ${loadaddr} ${fdtaddr}
i can boot the bsd.rd kernel manually.
So i need to use a newer u-boot i guess?
I use the imx_usb_loader method to write a new OpenBSD supplied
u-boot to the board:

As you can see, with this u-boot it says "Card did not respond to voltage
select!".
It does that when accessing mmc 0 or mmc 1, with a working card in it.
I've tried /usr/local/share/u-boot/mx6qsabrelite/u-boot-dtb.imx and
nitrogen6q/u-boot-dtb.imx. Both show this problem.
So, whats the right u-boot to use?
Also, if someone has it working, can you send a "printenv" output?
Thanks,
Benno
