[Buildroot] state of olimex_imx233_olinuxino_defconfig

[Phil Eichinger]

Hello

I recently tried olimex_imx233_olinuxino_defconfig and created the SD
card according to the readme.txt. It failed to boot with:
"
PowerPrep start initialize power...
Battery Voltage = 0.74V
No battery or bad battery
detected!!!.Disabling battery
voltage measurements./r/nLLCFeb 16 201616:01:38
EMI_CTRL 0x1C084040
FRAC 0x92926192
init_ddr_mt46v32m16_133Mhz
power 0x00820710
Frac 0x92926192
start change cpu freq
hbus 0x00000003
cpu 0x00010001
LLLLLLLFCLJ
"
Looks like the handover to the kernel is somehow broken, as it is not starting.

I then decided to drop mxs-bootlets completely and was able to boot it
directly with u-boot.
This requires an extra partition on the SD card where the uImage is
located (as per default u-boot environment).
So I changed my layout to:
16MB - type 0x53 - <uboot.sd>
a few MB - VFAT - copy uImage here
rest - Linux - <rootfs.ext2>

I am however not sure if I should submit an updated defconfig or a new
one like olimex_imx233_olinuxino_uboot_defconfig and extend the
readme.txt to cover both use cases?

Cheers, Phil

Sorry, no experience with imx233 / mxs-bootlets. Gustavoz, you've done
various updates to the defconfig. Does it work for you? Any hints?

Hi All.
Unfortunately i don't have an olinuxino in my hands any more.
It's very likely bootlets isn't happy with newer toolchain components - 
it's known to be somewhat fragile in that aspect, so if someone wants to 
update the defconfig to use uboot that would be great.
That wasn't a viable option when i added it since it didn't work vanilla.
Regards.

Hi,

Ok, I also prefer the saner approach using u-boot. I'll send a patch to
update defconfig, readme.txt and drop the bootlets patches.

Thanks, Phil
