i don't currently have access to the DB410C (colleague has wandered off with it), but what should be a couple simple questions.
i'm reading the Installation Guide here:
https://github.com/96boards/documentation/wiki/Dragonboard-410c-Installation...
and the basic recipe for installing the latest debian image without using fastboot is given in the section:
https://github.com/96boards/documentation/wiki/Dragonboard-410c-Installation...
i notice that that section clearly instructs the user to hook up a mouse, keyboard and monitor to do this graphically. can you not do that same install without all that hardware, like through the console port?
and if i read a bit further, i see that if one uses "fastboot", it appears that that would solve the problem. so if i had the board and only a power adapter and USB cable to support a terminal window, what would be the proper approach?

This section describes how to use the graphical installer (from SD card) and this is why USB keyboard and display are needed. However there are other methods , such as the one you mentioned later in your email, which don't require USB keyboard and display.
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 ;).
Anyways if your board comes up to fastboot you can flash with only USB cable and power. If your board is bricked and doesn't come into fastboot you can use the SD rescue card to bring it into fastboot mode.
and if i read a bit further, i see that if one uses "fastboot", it appears that that would solve the problem. so if i had the board and only a power adapter and USB cable to support a terminal window, what would be the proper approach?
Yes, as explained above.

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
Hello!
While we're at it, all links from this section point to Jessie, thus 404'd: https://github.com/96boards/documentation/wiki/Dragonboard-410c-Installation...

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.
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?
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?
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.
and if i want strictly a bootable image, would that be the rescue image under the "rescue" directory?
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.

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.

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..

... big snip ...
apparently, i have some reading to do. i guess i'm spoiled by earlier boards like the beaglebone black, where building a bootable SD card was trivially easy. anyway, off to the docs.
rday
p.s. just as a closer, what i'm after is, well, a doc entitled, "so, you want to build an SD card bootable image from the meta-qcom layer?". that's where i'm trying to go with this.
