Hi,
thanks, I just installed it and tried it.
Unfortunately, without a battery, it still behaves the same like last time I tried (about a year ago):
The keyboard LEDs flash up brightly for a split second, and that's it.
On serial out, I get nothing except for: U-Boot SPL 2016.11-01334-g2b143578a0-dirty (Jun 23 2018 - 22:23:08) OMAP5432-GP ES2.0
This happens both with 2GB and 4GB RAM boards.
If your PCB boots (you've got one of the very mainboards, AFAIR), then something clearly is different.
@hns: Can you boot the latest board revision that has been produced without a battery?

Hi,
I've collected all the mainboards I've got together and want to test which ones work (and what doesn't work) so I can prepare prototypes and send them out to devs.
I plan on using our Pyra OS rootfs, as that already has a setup to automatically run scripts on bootup, so I can write the testing scripts (so we can test all hardware features easily and comfortably).
However, as far as I know, the UBoot / Kernel used in our Pyra OS Setup only works if a battery is connected - which is horribly unconvenient if I just want to test bare boards.
Can someone give me a U-Boot which works fine without battery?
I've updated the one in http://packages.pyra-handheld.com/images/stretch/pyra-install.tgz to the latest gta uboot version (with the extlinux config patched in) As usual, it works on mine (booting fine without a battery), no idea if it works on the 4gb versions.
And which kernel is the best to use (where can I grab a binary)? I don't care about aufs at the moment, as that's not needed for th
testing scripts.
All kernels I've built are on the pyra repo, if you do an "apt-cache search linux-image" you'll get the full list of available kernels. The ones ending in -pyra have the aufs patches and a few config changes, the -letux ones are straight compiles from the letux repo. There are far more recent ones than the default kernel I use for the image on there, but they all have their problems (like the fbturbo driver failing on 4.16+ kernels, or not having a working tiler rotation)
