New bootloader getting stuck when loading kernel image
-
Hello all,
I am trying the new updates to the OnionIOT bootloader from thier repo that support DTS and FIT. I loaded the bootloader into my onion and it boots fine. However, when I try and boot my image (via tftp since because I wiped the memory of the onion) ot gets stuck at the same line after decompressing the image. Here are some logs of the process:

This is the update for the OnionIOT bootloader :

hi @baby-Onioneer, doesn't look so "baby" any more what you're doing here
Just to make sure: is this a Omega2+ with 128MB RAM? Because you definitely try to boot a "plus" kernel expecting 128MB:
[ 0.000000] Zone ranges: [ 0.000000] Normal [mem 0x0000000000000000-0x0000000007ffffff]0x0000000007ffffff = 128MB
The point in the startup sequence where it crashes is where a reference log of one of my omegas initializes (allocates?) some IP stack related tables, and if it tries to do that in the upper half of the supposedly installed RAM -> boom.

@luz hahaha, trying to become a full onioneer little by little.
It is the Omega2+. Here is a log of the boot process to see if I'm missing anything.

Net: eth0: eth@10110000 Hit any key to stop autoboot: 0 =>I did see that address 80800000 is outside the zone range of the memory but the load address is defined as 0x80800000 and trying to load it via tftp and booting anywhere else fails to decompress the image. Maybe thats the issue and just assumed it should work. Thought the offset would take care of that but maybe I am misunderstanding what the offset does
CONFIG_SYS_LOAD_ADDR=0x80800000
