07:11 topi`> jnettlet[m]: there is no spin up time on a SSD
08:41 topi`> question for HB users: anybody tried to hook up a CANbus onto the HB? what kind of connector(s) do you use?
08:42 topi`> there is FlexCAN builtin to the i.mx6, but a mikroelektronika CANboard could also be an option for prototyping
08:58 jnettlet[m]> topi`: there is an empty header for canbus on the HB2. Ilya will know the part number for it.
09:03 topi`> jnettlet[m]: I found out that the buffer chip connected to CANBUS is actually routed to two signals on the MicroSOM - CANBUS_TX and HDMI_CEC_TX
09:03 topi`> so no RX at all?
09:03 topi`> maybe rabeeh knows the answer
09:10 topi`> very odd message from dhclient on the macchiatobin:
09:10 topi`> DHCPDISCOVER on eth2 to 255.255.255.255 port 67 interval 3 (xid=0xb984ef65)
09:10 topi`> Unable to set up timer: out of range
09:10 topi`> so that's why eth2 doesn't get an IP, but it seems to be UP nevertheless
09:11 topi`> setting IP manually works though. Very odd
09:13 jnettlet[m]> topi`: travelling right now, but I am pretty sure the hdmi CEC TX line gets remixed to canbus rx
09:23 rabeeh> HDMI TX line is MX6QDL_PAD_KEY_ROW2__FLEXCAN1_RX
09:23 rabeeh> connectors wise you can use phoenix connector; 3 pin 2.5mm spacing
09:23 rabeeh> but then you need to remove the HDMI connector
09:26 topi`> so we'd need to order a custom build then?
09:26 topi`> I need to ask how many devices the customer needs
09:27 jnettlet[m]> topi`: just a custom device tree
09:28 topi`> a custom build, also, if we want to have the Phoenix connector there instead of the HDMI conn
09:28 topi`> you mean how to handle that pinmuxing where configuring that line to go into FLEXCAN1_RX?
09:34 jnettlet[m]> Yes.
09:35 topi`> damn, amazon prime is only available for customers in Germany or Austria. This is how "equal" the EU is currently :(
09:35 topi`> it seems that the only source for ClearFog boards inside EU is varia-store via amazon storefront
15:17 jnettlet[m]> topi`: I thought I had sent you a link to a reseller in the EU.
15:17 jnettlet[m]> of course you can always buy through AVNet, or Arrow
15:59 topi`> I wonder what happens to the bootorder on my mbin, if I add another SATA disk
15:59 topi`> right now the kernel is started with root=/dev/sda6
15:59 topi`> if I get unlucky, some other disk will insert itself as sda, and then I'd need to set root to /dev/sdb6
15:59 topi`> any ideas? I'd prefer setting the root via an UUID
15:59 topi`> I tried root=PARTUUID=aaaa-bbbb-ccc.... but did not work
16:01 Ke> you know that partuuid is not the same as filesystem uuid?
16:01 Ke> linux should support mounting based on partuuid, but not filesystem uuid
16:02 topi`> latter can be supported with an initrd, which I do not use on mbin
16:02 Ke> yes
16:02 topi`> let's see if I can ask the partuuid via GNU parted
16:02 Ke> blkid at least should give it to you
16:02 topi`> I'm running ubuntu yakkety
16:02 topi`> let's see
16:03 topi`> yeah blkid works
