Aug 22 06:25:23 <jfsimon1981> Good morning
Aug 22 10:03:53 <jfsimon1981> 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 ?
Aug 22 11:02:42 <zmatt> jfsimon1981: well, customers don't flash our devices
Aug 22 11:02:56 <zmatt> this is done during production
Aug 22 11:12:14 <zmatt> also, if you're trying to get my attention use zmatt not "Matt" .. I don't have a highlight on that
Aug 22 11:13:05 <jfsimon1981> Ok
Aug 22 11:13:43 <jfsimon1981> You mean you have special TI boards
Aug 22 11:14:10 <zmatt> no?
Aug 22 11:14:45 <jfsimon1981> I mean if i should go to SLC with the safe write bit on, how do we do this ?
Aug 22 11:15:30 <zmatt> we have a step in the flasher script we use during manufacturing of our product that invokes the mmc utility
Aug 22 11:16:39 <zmatt> https://pastebin.com/ehRuNFbL
Aug 22 11:18:11 <jfsimon1981> You start for a standard BBB and have a specific microSD flasher
Aug 22 11:18:14 <jfsimon1981> is this right ?
Aug 22 11:18:48 <zmatt> yeah, we plug the BBB into our mainboard and boot from a custom flasher sd-card
Aug 22 11:19:15 <jfsimon1981> i see
Aug 22 11:19:26 <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
Aug 22 11:19:42 <zmatt> reconfiguring the eMMC is just one of these steps
Aug 22 11:20:01 <jfsimon1981> so i need to build a stripped sown linux os with the flasher, ok
Aug 22 11:20:14 <jfsimon1981> i see thanks
Aug 22 11:21:58 <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)
Aug 22 11:22:49 <jfsimon1981> i'll work on it
Aug 22 11:22:54 <jfsimon1981> thank you
Aug 22 12:41:57 <jfsimon1981> zmatt do you work for ti somehow ?
Aug 22 12:42:09 <jfsimon1981> I see you contrubuted to uboot and other projects too
Aug 22 12:50:46 <zmatt> no
Aug 22 12:51:01 <jfsimon1981> ok
Aug 22 12:51:14 <zmatt> I work for a speaker company
Aug 22 12:51:22 <jfsimon1981> yes
Aug 22 12:51:42 <jfsimon1981> you integrate a bb with it ?
Aug 22 12:52:23 <zmatt> yes... we have switching to an osd335x-based design somewhere on our to-do list but never seem to get around to it
Aug 22 12:53:19 <jfsimon1981> ok
Aug 22 12:54:07 <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
Aug 22 12:54:47 <jfsimon1981> not super critical for this first unit but i should do for reliability.
Aug 22 12:55:14 <jfsimon1981> Specially since at the moment it is power off shutdown
Aug 22 13:12:04 <angad_kumar> Hi, I am trying to run gpio read code in my Beaglebone black. I am getting below errors, can someon
Aug 22 13:12:20 <angad_kumar> Traceback (most recent call last):
Aug 22 13:12:21 <angad_kumar>   File "test.py", line 4, in <module>

Aug 22 13:12:22 <angad_kumar> ValueError: Set gpio mode failed, missing file or invalid permissions.
Aug 22 13:12:59 <angad_kumar> can someone help me resolve the above error?
Aug 22 13:24:14 <jfsimon1981> Hi something like this ?
Aug 22 13:24:18 <jfsimon1981> GPIO.setup("P8_10", GPIO.OUT)
Aug 22 13:24:18 <jfsimon1981> GPIO.output("P8_10", GPIO.HIGH)
Aug 22 17:27:46 <rcn-ee> zmatt: .... v6.0-rcX just removed our devm_gpio_free entry point.. reverting for now... https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v6.0-rc2&id=2b038e786f8338a3bc22d791000753e0ec113e00
Aug 22 18:32:01 <zmatt> yeah I should rewrite gpio-of-helper to use the newer API
