In fact you can even use the graphical installer from the command line serial console (e.g. Without the GUI, but this is not documented ;).
ah, that would solve the problem, then. any reason why that's not documented? it's the first possibility that occurred to me to look for.
well, it's possible, but not meant to be used this way. To add proper headless support would require a bit of polishing in the flashing tool. We have a bug opened for that.. https://bugs.96boards.org/show_bug.cgi?id=58
ok, time for a few more questions while i wait for my colleague to return my DB410C. yes, some of these are trivial questions, but sometimes the wording in the docs is not as precise as i'd like.
patches are welcome ;-) if you make minor changes, feel free to make them, if you want to make larger changes, please make pull request so that we get a chance to review.
first, while i have zero interest in android and will eventually reflash the eMMC, for now, i'll just play it safe and leave android where it is and boot straight from SD card. AIUI, as long as there is a valid bootloader(?) in eMMC, that will be used for booting unless i physically flip the S6 ("SD BOOT") switch to ON. so if i want to leave android where it is and just boot from SD, i'll just throw S6 and leave it on for now, correct?
If you boot from SD, then the eMMC will be untouched. It's S6-2 switch, btw. However please note that we don't provide images to be used on SD cards, you will need to make yours. But that shouldn't be a problem. I think Ubuntu Core from Canonical comes is delivered as a bootable SD card and they preserve the eMMC content.
now, as for a bootable image, eventually, i'll build my own using OE and the meta-qcom layer but, just for testing, i can use an image from somewhere under:
http://builds.96boards.org/snapshots/dragonboard410c/linaro/
yes?
yes, you can. you can refer to https://github.com/96boards/documentation/blob/master/ConsumerEdition/Dragon..., for example, and use the rootfs from our Debian builds instead of the OE images.
however, the aforementioned dragonboard410c_sdcard_install_debian-236.zip image is not just a bootable but an *installation* image. when it boots, do i get the option *not* to install if i just want to boot from it? the doc doesn't seem to mention that.
no, you can't. it is an installer image, it is useful *only* if you want to erase the eMMC.
and if i want strictly a bootable image, would that be the rescue image under the "rescue" directory?
nope. the Rescue image will boot from SD, and put the board into fastboot mode, so that you can use fastboot on your PC to reflash (rescue) the board. When running 'fastboot flash <partition> <file>' from your PC, you will flash into eMMC!
normally, when i pick up a new dev board, the absolutely very first thing i try to do is download a bootable image and boot from it, without changing anything on the board. i would think that any "getting started" guide would explain how to do that as the very first step.
thanks for the feedback. It is actually a good idea to add such image. I will do it ;-) but it doesn't exist yet.. so right now, you would need to cook up your own SD card using the instructions from the wiki..
