Have you tried? I'm typically doing just a plain "make". According to "make help", a plain "make" (assuming it's equivalent to "make all") includes "zImage" and "dtbs" targets. > > Instructions say "make -j", which is nice way to crash a machine.

And the framebuffer console (though only by the means of a hacked pxa168fb for the time being, no armada drm yet) works. Here's my bootup banner: OLPC 1B1, 800 MHz, 512 MiB memory, 4 GB internal storage... OpenFirmware Q4D38 EC Firmware 1.0.01 2018-10-30 19:11:36 UTC I seem to have a bit newer OF. > Type any key to interrupt... > (but keys do not interrupt anything, ouch). In my version of the OLPC OF the routine is replaced with one that only accepts the Escape key, because kids like to press random keys without really wanting a shell. Maybe try that one? Although my prompt is also a bit different: "Type the Esc key to interrupt automatic startup" > Warning... partition type is 0xb... > Boot device: /usb/disk:\boot\olpc.fth Arguments: > Boot device .... > Warning... partition type is 0xb... Maybe the older version wouldn't support a VFAT volume, hence the complains about the id=0xb volume?

The topmost commit in the same repository is the build configuration that was used to generate it: https://github.com/hackerspace/olpc-xo175-buildroot/commit/71783d599.patch Note it is only going to boot off the SD card, because the root= argument is hardwired in the devicetree. Sorry about that -- I built the image before I noticed you're booting off an USB stick and I don't have the resources to regenerate the image at the moment. If this won't boot for you, we may need fixes for older FW. Until then it might be a good idea if you just update to the latest one (it is as easy as booting the last version of the stock distro with a charged battery pack). > Thanks. > > > Pavel Take care Lubo
