Hi,
It seems there were some OMAP5 related fixes since v2015.10, so I've rebased hns' letux-extensions u-boot branch hoping it would help to boot my board. Unfortunately it did not help (my board still always hangs/crashes randomly in u-boot or the kernel, if it manages to reach it), but maybe somebody will find it useful:
git://git.openpandora.org/pandora-u-boot.git letux-extensions-v2016.07
While this u-boot works the same as hns' build for me (sometimes boots), MLO (aka SPL) won't even show any signs of life. Haven't tried to investigate why.

good work! I will try this as soon as I am back in my lab...
If it works we should simply move forwards to 2016.07.

Maybe it needs a trick to compile or install.

BR and thanks, Nikolaus

I'm not sure if by "board" you mean the evm or a pyra prototype, but on my evm this versions (built with pandora_pyra_lc15_defconfig, im not sure if that's the right one) seems to work fine.
I installed it on an sd card with:

Pyra prototype, probably with some hardware issue.
my evm this versions (built with pandora_pyra_lc15_defconfig, im not sure if that's the right one) seems to work fine.
I've also used pandora_pyra_lc15_defconfig.
Not sure if running this stuff on an EVM is a good idea, at least some GPIOs differ and hns' u-boot enables all the LEDs (keypad backlight and such, perhaps more?) early which may or may not conflict with something on the EVM.
Perhaps he can comment himself if it's safe.
I installed it on an sd card with:
dd if=/dev/zero of=${DISK} bs=1M count=10 dd if="$UBOOT/MLO" of=${DISK} count=1 seek=1 bs=128k dd if="$UBOOT/u-boot.img" of=${DISK} count=2 seek=1 bs=384k

Interesting, what compiler have you used for this?

It hasn't exploded yet :) And i think all the important bits are pretty much the same anyway.

gcc (Debian 4.9.2-10) 4.9.2 , from debian jessie, running on the evm.
Been using a 2016.07 u-boot with a custom extlinux/distro config on the evm for quite a while now without any issues. (see doc/README.distro in uboot)

Well, it won't but it may break some features which you do not see immediately.

Not really. The EVM needs a different setup than the Pyra for the tca6424. Less important is that the Pyra U-Boot tries to program the bq24297. This is simply ignored if it is not installed.
So you should use the evm defconfig on evm and the pyra_lc15 on pyra only.
