Hi Everyone, I just received a z2 and looking for a way to access the boot console. I checked linux.wireless.com and was unable to access the hardware pin-out for the connector on the back. What's the easiest way to get my own rootfs onto the device? |
| [12:34:13] |
<Magon> |
angelr: miniSD card |

Hi Magon, Thanks for your reply. How do I configure the boot loader to use the miniSD card as the root device? Is it preconfigured to do so? |
| [13:57:30] |
<Magon> |
angelr: are you registered on linux.zipitwireless.com? |
| [14:09:02] |
<angelr> |
Magon, I am not. If I register, will I be able to find the answers to similar questions? |
| [14:09:18] |
<Magon> |
angelr: yes |

bryank: ping |
| [21:22:39] |
<bryank> |
mi_dave: hey |
| [21:22:49] |
<bryank> |
from earlier today -- i'm pretty sure the PW is blank |
| [21:22:59] |
<mi_dave> |
yeah for root but are there any other users? |
| [21:23:24] |
<bryank> |
a few, but they look like they're for daemons |
| [21:23:27] |
<bryank> |
and you can't log in as them anyway |
| [21:28:21] |
<mi_dave> |
okay, what should i be trying out? I see a couple issues already. 1) whatever screensaver/powersave mode is configured ends up displaying random horizontal lines on screen |
| [21:28:47] |
<mi_dave> |
2) my guess is there needs to be a service written to handle charging the battery |
| [21:29:14] |
<mi_dave> |
which will probably require some help from drmikecrowe since i haven't seen any hardware details listed for the charging/monitoring circuit yet |
| [21:29:20] |
<bryank> |
oh boy |
| [21:29:33] |
<bryank> |
does the battery not charge, or does it just not light up leds? |
| [21:29:37] |
<mi_dave> |
where would i find the wpa supplicant conf file? |
| [21:29:56] |
<bryank> |
it takes a config file as an argument, but i don't even see its binary installed... |
| [21:32:50] |
<mi_dave> |
The battery was charging under the zipit setup (yellow batt led) but after the reboot into the sd card the led was green. i ran the shell for a while and then restarted the zipit stuff and the charger kicked in again (or the yellow led at least) |
| [21:32:59] |
<mi_dave> |
this was all while plugged into ac power |
| [21:33:02] |
<bryank> |
however, bitbake did create a few .ipk files |
| [21:33:13] |
<bryank> |
on charging: that's obviously wrong, but i'm not sure what's going on |
| [21:33:58] |
<bryank> |
is there a /sys/class/power_supply directory? |
| [21:34:48] |
<mi_dave> |
maybe the charging circuit is autonomous and the led indication defaulted to green |
| [21:34:53] |
<mi_dave> |
no /power_supply dir |
| [21:34:59] |
<bryank> |
dang, kernel's too old then -- what about anything related to power under /proc/acpi? |
| [21:38:37] |
*** |
nhoman_ has joined #zipit |
| [21:38:53] |
<mi_dave> |
no acpi dir either |
| [21:38:58] |
<bryank> |
... |
| [21:39:02] |
<bryank> |
oh, duh, that's because acpi is x86-only |
| [21:39:30] |
<bryank> |
no idea how to tell what's providing power to the device then.. |
| [21:41:51] |
<mi_dave> |
keyboard response is not great either (no disrespect to ethicalclone) |
| [21:42:37] |
<bryank> |
because it's polling? or can't you tell for sure? |
| [21:42:41] |
<mi_dave> |
so the wpa supplicant was not part of the base image? |
| [21:42:42] |
<bryank> |
i don't know if the gpio stuff can generate interrupts... |
| [21:42:51] |
<bryank> |
looks like it was part of the base image, sort of. not on the rootfs, but it did build a package |
| [21:43:41] |
<mi_dave> |
keyboard response - you have to wait after holding alt or shift down before hitting the 2nd key for it to see the 2nd key press |
| [21:44:27] |
<mi_dave> |
occasionally autorepeat kicks in unexpectedly but i think that is usually when shift-ing or alt-ing |
| [21:44:32] |
<mi_dave> |
minor issues |
| [21:44:38] |
<bryank> |
yeah, hopefully |
| [21:44:46] |
<bryank> |
not sure if they're fixable (would depend on what's going on exactly) |
| [21:48:53] |
<mi_dave> |
still pretty cool to be running a linux shell on such a small device |
| [21:49:11] |
<bryank> |
yep :-) |
| [21:49:19] |
<bryank> |
on wpa_supplicant: looks like the package uses /etc/wpa_supplicant.conf, i think |
| [21:49:21] |
<mi_dave> |
any idea what controls the screen blanking/screensaver? |
| [21:49:29] |
<bryank> |
not really... |
| [21:51:58] |
<mi_dave> |
no w* under /etc. would it be hidden? |
| [21:52:08] |
<bryank> |
no, it just didn't get installed, i think |
| [21:52:11] |
<bryank> |
into the .tar.gz file that i used to generate the sd card |
| [21:52:46] |
<bryank> |
er, .tar, not .tar.gz |
| [21:53:04] |

<mi_dave> |
including a couple named [wlan_... |
| [21:54:00] |
<bryank> |
any difference with ps -e? or "ps -e --format=pid,command" to see more of the cmdline |
| [21:54:11] |
<bryank> |
the [] processes are kernel threads |
| [21:54:16] |
<bryank> |
i.e. not really processes |
| [21:54:28] |
<mi_dave> |
ps barks with a BusyBox error with any switches and says Usage: ps |
| [21:54:31] |
<bryank> |
oh -- well never mind then |
| [21:59:21] |
<mi_dave> |
any other useful commands that I've forgotten? |
| [21:59:30] |
<bryank> |
check around in /bin and /sbin, plus /usr/bin and /usr/sbin ;-) |
| [21:59:44] |
<bryank> |
(no idea what of that would be "useful" though) |
| [22:02:15] |
<mi_dave> |
not sure if the rtc implemented. how do i display local time? |
| [22:02:30] |
<bryank> |
date |
| [22:02:33] |
<bryank> |
or "TZ=EDT date" |
| [22:02:34] |
<bryank> |
er, EST |
| [22:02:48] |
<mi_dave> |
it is now jan 1 1970... oh well |
| [22:03:01] |
<bryank> |
todo: figure out if ntpd will build |
| [22:03:54] |
<mi_dave> |
uh oh, i type more to see if it was implemented and now i'm stuck. do i need a ctrl-C? |
| [22:04:06] |
<bryank> |
the program more? q might exit as well as ctrl-c |
| [22:04:57] |
<mi_dave> |
no q no ctrl-c no power button. looks like a reset... |
| [22:08:25] |
<bryank> |
ctrl-\ possibly? |
| [22:08:30] |
<bryank> |
(i think that's what sends sigquit) |
| [22:09:11] |
<mi_dave> |
wow - well now i know how to generate a ctrl-c with no ctrl key |
| [22:09:42] |
<bryank> |
? |
| [22:09:58] |
<mi_dave> |
so i was attempting to pipe the ls output to more. what pipe/redirection character do i need? |
| [22:11:37] |
<bryank> |
not sure how to type it on that keyboard, but it's the | character... |
| [22:11:44] |
<bryank> |
shift-backslash on a normal PC keyboard |
| [22:11:58] |
<bryank> |
(well, US layout anyway) |
| [22:12:04] |
<mi_dave> |
not labeled anywhere but let me lookup ethicalclone's keyboard map |
| [22:14:14] |
<mi_dave> |
the map on the wiki is not complete. not sure where i saw a more complete map |
| [22:14:27] |
<mi_dave> |
i think it was in a file somewhere |
| [22:14:41] |
<bryank> |
there was a keymap file that i remember looking at somewhere; let me see if i can find it in the oe tree somewhere |
| [22:27:21] |
<bryank> |
ah hah -- zipkeymap.map in the fatroot -- does alt-1 work? |
| [22:27:22] |

tilde |
| [22:32:46] |
<bryank> |
hmm; supposedly alt-1 was "bar", which is shift-backslash on my (PC) layout |
| [22:32:55] |
<bryank> |
shift-backslash is also supposed to be "bar" in zipkeymap.map |
| [22:32:56] |
<mi_dave> |
i think with the matrix layout certain key combinations are not possible - at least with the current driver |
| [22:33:10] |
<bryank> |
or ctrl-< maybe? |
| [22:33:25] |
<bryank> |
yeah, could be |
| [22:34:43] |
<mi_dave> |
no backslash labeled. oh well, enough for tonight. i'll bring it in tomorrow and you can drive |
| [22:34:53] |
<bryank> |
(and we've monopolized the irc channel long enough too ;-) ) |
| [22:35:00] |
<mi_dave> |
sorry folks... |
| [22:37:43] |
<bryank> |
anyway, see you tomorrow |
