IRC #olimex 2015-08-13

[15:58:13] <zekoZeko> hello everyone. I'm looking for something to replace an RPi that is giving me trouble (unstable even with a good power supply, SD cards corrupting data etc...).
[15:59:11] <zekoZeko> I need it to connect via Ethernet, run Asterisk and fiddle a few GPIO pins when a call comes from a known number :)
[15:59:46] <zekoZeko> A10-OLinuXino-Lime-4GB should be more than enough for that, right?
[16:01:16] <zekoZeko> can it provide +5V power for an external board (very little current needed, just a few resistors & stuff for connecting to the old intercom and key fob for the parking ramp)
[16:01:43] <zekoZeko> right now it takes the power from one of the RPi GPIO pins...
[16:07:44] <adj_> zekoZeko, i don't own an Lime board but a bunch of other Olimex boards, including an A20-Lime2 board
[16:07:49] <adj_> very happy with them
[16:08:13] <adj_> Lime looks a good board for your needs
[16:09:56] <adj_> but I would suggest you a board without on board flash, using only the sd-card
[16:11:33] <adj_> i mean, A10/A20-Olinuxino-Lime, not the 4GB version
[16:13:35] <zekoZeko> i see
[16:13:49] <zekoZeko> i was looking at the onboard flash one to get rid of possible problems with SD card contacts
[16:14:33] <zekoZeko> it won't do much writing anyway, I already send all the log data to a remote syslog server and don't write to /var/log
[16:20:01] <zekoZeko> adj_: is there a reason to not use the onboard flash? 4GB is more than enough for what I need.
[16:21:27] <tbr> are those real eMMCs or is that unmanaged NAND
[16:21:55] <tbr> that's mildly annoying on the A10s, it has NAND, but you can't use it unless you use their proprietary driver foo
[16:22:09] <zekoZeko> i see
[16:59:20] <zekoZeko> what's the boot process on there boards? can i use serial to debug if something goes wrong?
[16:59:45] <zekoZeko> i had to lug a bloody monitor around to run fsck on the bloody RPi because it would not boot...
[17:07:06] <tbr> mh? even the cRaPi has a serial console IIRC
[17:07:35] <tbr> and yes, my A10s only saw a HDMI display once, because I wanted to see if that works.
[17:09:16] <zekoZeko> tbr: it probably has it, it's just that I never had a will to learn much about it, this project just landed in my lap because there was noone else to do it :)
[17:09:52] <zekoZeko> and i'm losing my patience over it, i'm used to work with more reliable stuff :)
[18:01:17] <adj_> zekoZeko, I think that NAND support is mainlined with some allwinner SOCs, but not sure
[18:02:44] <adj_> about why I don't recommend it: boards with NAND are 10€ more expensive, speed is much lower than with sd-card, sd-cards are replaceable if they fail, writing the image on the card is easier...
