Hello Matt, I'm looking how to flash SLC and enable the safe write in eMMC controller, is there any resources or did you build a customer flasher image for this purpose ?
<jfsimon1981>
You start for a standard BBB and have a specific microSD flasher
<jfsimon1981>
is this right ?
<zmatt>
yeah, we plug the BBB into our mainboard and boot from a custom flasher sd-card

i see
<zmatt>
which performs some hardware tests, gathers hardware information, generates ssh keys, registers the device in our database, flashes eMMC, flashes an SPI flash on our custom mainboard, etc
<zmatt>
reconfiguring the eMMC is just one of these steps
<jfsimon1981>
so i need to build a stripped sown linux os with the flasher, ok
<jfsimon1981>
i see thanks
<zmatt>
yep we just have a minimal system on it, custom tools, and an image file that's flashed to eMMC (making sure to randomize things that should be unique per device, such as the filesystem uuid, machine id, and obviously ssh key)
<jfsimon1981>
i'll work on it
<jfsimon1981>
thank you

no
<jfsimon1981>
ok
<zmatt>
I work for a speaker company
<jfsimon1981>
yes
<jfsimon1981>
you integrate a bb with it ?
<zmatt>
yes... we have switching to an osd335x-based design somewhere on our to-do list but never seem to get around to it
<jfsimon1981>
ok
<jfsimon1981>
this week i'll be release a prototype for serie with the BB for the core, i'll see if i manage to burn the emmc properly
<jfsimon1981>
not super critical for this first unit but i should do for reliability.
<jfsimon1981>
Specially since at the moment it is power off shutdown
