nicksydneyhi .. i have question for Android... for Android-IA as per the instruction here does this mean that the lollipop version ONLY support minnowmax ? ..for KitKat version any baytrail process device can boot up but seems like for lollipop i've tested does not work ...are there any specific requirement ?08:44
*** yocti <yocti!> has joined #minnowboard08:51
nicksydneyhmm...plugging the UART cable to the device provide some more insight...seems like fastboot is booting but something is not working08:56
nicksydneythis is what i'm getting
nicksydneycould this be the problem [    1.155106] [drm:intel_hdmi_get_edid] *ERROR* Get_hdmi cant read edid08:57
nicksydneynever mind fix the problem09:00
*** Abhishek_ <Abhishek_!uid26899@gateway/web/> has joined #minnowboard09:06
nicksydneyinstalling via fastboot on non-minnow is not going to be will easier if the live_img target that was in KK introduced back to lollipop09:33

warthog9lack of caffeiene is a dangerous state22:43
nicksydneytried the image produced in 5.0.1_r1-ia1 using the liveimage target and doesnt' work .. from the serial output seems like something is not right in the packaging..anyone has tried and working before ?22:53
nicksydneyusing fdisk  -lu on both kitkat and 5.1 .img file there is difference22:58
nicksydneythis is the output for fdisk -lu on the live.img file from both version
nicksydneysorry this output  is from android-5.1.0_r1-ia022:59
warthog9nicksydney: downgrade to 0.79 firmware23:03
warthog9android apparently tries to create the same sysfs entry for multiple displays found, and 0.80 enabled multiple displays23:04
nicksydneywarthog9: i'm testing it not using minnowmax but baytrail pc23:04
warthog9nicksydney: same fundamental problem, but I don't have a good answer on how to fix it23:04
nicksydneywarthog9: so 5.1 will require firmware upgrade regardless of what kind of baytrail processor ?23:05
warthog9nicksydney: until someone resolves the android kernel attempting to make the same sysfs entry Android 5.1 won't work (won't get to a graphical screen anyway)23:06
warthog9the fix on the MAX is to back the firmware down to 0.79 from 0.8023:06
warthog9on other baytrail systems, the only solution may be to wait for a fix in Android itself23:07
nicksydneywarthog9: i'm trying to understand that this is relevant to kernel related issue or firmware ? as you mention downgrading firmware works for baytrail ?23:07
nicksydney^^^^ baytrail minnowmax i meant23:07
warthog9nicksydney: lets break this down, you are trying to boot android 5.1 on an MAX, and you aren't ever getting a gui screen ever, correct?23:08
nicksydneywarthog9: no i'm trying to boot 5.1 not on a minnowmax .... i've got a baytrail PC that works with Intel-IA 4.423:09
warthog9but the problem is fundamentally the same, you try to boot and you never get a gui screen?23:10
nicksydneywarthog9: i get the Intel big logo with warning and also message of pressing UP or DOWN arrow..UP for continuing to boot which I did and then after few minutes blank screen it reboots ...was able to get the serial output  from the PC which is this

warthog9the problem boils down to Android can't handle multiple hdmi screens23:15

warthog9we tripped over this when we updated the firmware on the max from 0.79 to 0.80, where we enabled support for multiple monitors23:17
nicksydneyinteresting....but what this error23:17

nicksydneyseems like it cannot find the filesystem for some reason OR is it because of the HDMI issue it failed to init properlyh ?23:18
nicksydneyas i compared file .img file produced from 4.4 and 5.1 using fdisk -lu and this is the output
nicksydneyfor 4.4 i can see there is a partition23:19
nicksydney./live.img1   *        2048      497663      247808    c  W95 FAT32 (LBA)23:19
nicksydneywhile 5.1 no partition inside23:19
warthog9have you checked the md5/sha1 of what you downloaded?23:20
nicksydneyi built from the source23:20
nicksydneyusing the 'minnow_max-userdebug' target from 5.123:20
nicksydneyusing the make command 'make -j8 liveimage'23:21
nicksydneythere isn't any liveimage .img file build that is available from Intel-IA website23:22
nicksydneyall that is available is the fastboot .img file which is not workable for non-minnowmax system23:22
warthog9sadly you've outstripped what I know of in the build process for Android :-/23:22
nicksydneyin kitkat there is a live_img build target that allow dev to boot up system without installing and i think 5.1 replacement for that is liveimage but there could be a bug  or maybe i missed  a step to produce the .img file23:23
warthog9nicksydney: best I can do is point you at the android mailing list, as I'm not sure android-ia@lists.01.org23:25
nicksydneywarthog9:  ok will post there ..thanks for the help23:25
warthog9no problem :-)23:26
