| 10:28 | Exaga | morning all :> |
| 11:06 | malte | morning |
| 11:07 | Exaga | hi malte |
| 11:07 | malte | hey Exaga |
| 11:07 | Exaga | :> |
| 11:07 | Exaga | i have the i2ex booting with debian using kernel 3.14.14 |
| 11:07 | malte | great |
| 11:07 | Exaga | but i'm missing modules |
| 11:08 | Exaga | so just fixing that and rebooting |
| 11:08 | Exaga | working my way through dmesg as we speak hehe |
| 11:26 | Exaga | although it's booting my display goes blank during boot but i can login via ssh |
| 11:26 | Exaga | i wonder if there's a uEnv.txt setting i am missing |
| 11:27 | Humpelstilzchen | Exaga: dvi? |
| 11:28 | Exaga | bootfile=zImage |
| 11:28 | Exaga | mmcargs2=setenv bootargs root=/dev/mmcblk0p2 ro rootwait video=mxcfb0:dev=hdmi consoleblank=0 ${bootargs_ext} |
| 11:28 | Exaga | mmcargs=if test ${cpu} = 6SOLO; then setenv bootargs_ext gpumem=64M fbmem=10M; else setenv bootargs_ext; fi; run mmcargs2 |
| 11:28 | Exaga | maybe i am missing something |
| 11:29 | Exaga | this is the old uEnv.txt from the stock debian jessie install |
| 11:29 | Exaga | i only changed bootfile=uImage to bootfile=zImage |
| 11:32 | Exaga | Humpelstilzchen: i have a hdmi cable plugged in |
| 13:47 | cybertim | got my hummingboard today, but im a bit puzzled, i flashed the latest 'jessie' debian to an 4gb sd, i can see the greenlight flash but nothing out of the hdmi/analog out also not showing up on the network |
| 13:47 | cybertim | is there a way to debug this, or is the latest jessie image not compatible wth the hummingboard? |
| 13:48 | Exaga | what type of borad cybertim ? |
| 13:48 | Exaga | i2, i2ex? |
| 13:48 | cybertim | the i1 |
| 13:48 | Exaga | right |
| 13:48 | Exaga | did you just write the image to the sd card and try booting it? |
| 13:49 | cybertim | yes i 'dd'ed it and booted it on the hummingboard |
| 13:49 | Exaga | well i am informed that this image is the best one to use: |
| 13:49 | Exaga | http://www.igorpecovnik.com/2014/08/19/cubox-i-hummingboard-debian-sd-image/ |
| 13:49 | Exaga | the word is that it's better to use this than the stock debian jessie |
| 13:50 | Exaga | i have an i2ex but i haven't tried this image yet |
| 13:50 | cybertim | im also downloading the old jessie image now from solidrun |
| 13:50 | cybertim | since i need jessie:P but i can also distupgrade from wheezy |
| 13:50 | cybertim | will download that one as well |
| 13:51 | Exaga | i'm testing with the solidrun jessie |
| 14:02 | cybertim | hm got something out of it, but by replacing the power source, it was 500ma now 850ma - but during the boot process get a lot of stacktraces and it stops.. |
| 14:03 | cybertim | what is the min. ampere rating? |
| 14:03 | Exaga | 2A i think |
| 14:03 | Exaga | i am not sure |
| 14:04 | cybertim | hm thats a lot ;) will search for a bigger adapter |
| 14:13 | Exaga | 3. Power Adapter: you may choose your own power adapter, make sure to use a power adapter with the |
| 14:13 | Exaga | following specification: |
| 14:13 | Exaga | Regulated 5V supply with 2A source capacity. |
| 14:13 | Exaga | Micro USB plug type. |
| 14:13 | Exaga | http://www.solid-run.com/wp-content/uploads/2014/06/SolidRun_UM_HummingBoard.v-1-1.pdf |
| 14:13 | Exaga | Use only limited power source (LPS) power adapter with adequate protections. Power adapter |
| 14:13 | Exaga | should meet local safety regulations. |
| 14:14 | dv_ | heh, I imagine the picture. next the cubox, a fire extinguisher, "just in case" |
| 14:14 | dv_ | *next to |
| 14:14 | Exaga | :D |
| 14:38 | cybertim | hm got it 'working' now the 'root fs cannot be mounted' unknown type etc.. is this because i use HC mini sd? |
| 14:38 | cybertim | will try the Igor debian image as well now :P |
| 14:38 | Exaga | not sure mate sorry |
| 14:39 | Exaga | might be just an error msg because the rootfstype=ext4 |
| 14:39 | cybertim | it states that it tried ext4 and a bunch of others and that it is 'unknown' maybe its just corrupted, will dd again |
| 14:40 | cybertim | use another card |
| 14:51 | cybertim | its working, omg ;) 1.2A power adapter (even with some 2a didnt work, think the ratings werent so good) and the new jessie image on another sd crd |
| 14:52 | cybertim | the igor image didnt show anything on screen.. |
| 14:52 | cybertim | and the old jessie just bugs out |
| 14:53 | jnettlet | cybertim, a lot of the 2a chargers especially if for use with the iphone need special cables to go into "fast charge" mode |
| 14:54 | jnettlet | the standard for normal android phones is that they have the tx/rx pins shorted |
| 14:54 | cybertim | i used a universal one, but switching the volt to 5 also scales the amperage i guess |
| 14:54 | cybertim | probably 2a on 1volt :P |
| 14:54 | jnettlet | without those pins shorted it will only output normal USB 1.1 voltage |
| 16:08 | Exaga | ah... this forum thread explains it all... |
| 16:08 | Exaga | http://www.solid-run.com/community/topic1547.html |
| 16:11 | jnettlet | hey somebody actually read my warning message. excellent! |
| 16:11 | Exaga | which message? :> |
| 16:12 | jnettlet | WARN: Cannot load the DTB and boot file is type zImage |
| 16:12 | jnettlet | if you have not appended a dtb to the file it may |
| 16:12 | jnettlet | hang after displaying Starting kernel... |
| 16:13 | Exaga | so the problem has a solution? |
| 16:14 | jnettlet | yes make sure you have the proper .dtb files in the same directory as your zImage |
| 16:14 | Exaga | well i have an i2ex |
| 16:15 | jnettlet | and??? |
| 16:15 | Exaga | and i do not know how to append a dtb to the file :> |
| 16:15 | Exaga | can you tell me please? |
| 16:15 | jnettlet | you don't need to. Just make sure the file that is looking for is in the same directory as your zImage file |
| 16:16 | Exaga | ok |
| 16:17 | Exaga | do i just need 1 .dtb file to match my hardware? |
| 16:17 | Exaga | and do i use imx6dl or imx6q for the i2eX? :> |
| 16:18 | Exaga | i guess imx6dl |
| 16:18 | Exaga | imx6dl-hummingboard.dtb |
| 16:18 | jnettlet | The error message tells you. |
| 16:18 | jnettlet | ** File not found /boot/imx6q-hummingboard.dtb ** |
| 16:18 | jnettlet | WARN: Cannot load the DTB and boot file is type zImage |
| 16:18 | jnettlet | if you have not appended a dtb to the file it may |
| 16:18 | jnettlet | hang after displaying Starting kernel... |
| 16:18 | Exaga | that's it yes |
| 16:19 | Exaga | so which file exactly needs to be in /boot along with zImage ? |
| 16:20 | jnettlet | ** File not found /boot/imx6q-hummingboard.dtb ** |
| 16:20 | Exaga | ok i'll try it |
| 16:20 | Exaga | thanks for your advice :> |
| 16:20 | jnettlet | good luck |
| 16:20 | Exaga | thank you |
| 16:21 | Exaga | imx6dl-hummingboard.dtb is in the same place as zImage |
| 16:22 | Exaga | and the screen is blank after the kernel loads |
| 16:22 | Exaga | i can still log in via ssh |
| 17:33 | earthy | that implies that the kernel is not informed of the wish to output to hdmi or the OS does not start a login process on the hdmi tty |
| 17:35 | paulk-aldrin | hey, I get no sound on my cubox-i with debian jessie and hdmi output |
| 17:35 | paulk-aldrin | looks like pulseaudio is using the right alsa card |
| 17:35 | paulk-aldrin | (which shows no controls, btw) |
| 17:35 | paulk-aldrin | but no sound output |
| 17:35 | paulk-aldrin | now I noticed that the SDMA firmware is not being loaded, because it requests it *before* rootfs is mounted |
| 17:36 | paulk-aldrin | so question is: should I use an initramfs with the sdma firmware? |
| 17:36 | paulk-aldrin | or else, how do I make it load it? |
| 17:36 | paulk-aldrin | (provided that's why hdmi audio doesn't work) |
| 17:36 | Humpelstilzchen | hdmi audio needs firmware? |
| 17:36 | paulk-aldrin | SDMA does |
| 17:36 | paulk-aldrin | and HDMI audio supposedly relies on SDMA |
| 17:36 | paulk-aldrin | well, SDMA doesn't, but it's better with the firmware |
| 17:37 | paulk-aldrin | thankfully |
| 17:37 | Humpelstilzchen | I don't think I have fetched a firmware for that |
| 17:37 | Humpelstilzchen | paulk-aldrin: did you just try aplay? |
| 17:37 | paulk-aldrin | does it work for you (HDMI audio)? |
| 17:37 | Humpelstilzchen | hdmi works yes |
| 17:37 | paulk-aldrin | Humpelstilzchen, aplay, pulseaudio, mplayer, vlc, nothing produces audio |
| 17:37 | paulk-aldrin | Humpelstilzchen, care to share a dmesg? |
| 17:38 | paulk-aldrin | I'm using 3.14 |
| 17:38 | Humpelstilzchen | same |
| 17:38 | Humpelstilzchen | paulk-aldrin: sorry currenty no access from here |
| 17:38 | paulk-aldrin | ok |
| 17:39 | Humpelstilzchen | ok |
| 17:39 | paulk-aldrin | Humpelstilzchen, the firmware is in the kernel source, so it's likely that it was installed along with the modules btw |
| 17:39 | Humpelstilzchen | I have a dmesg |
| 17:39 | Humpelstilzchen | posted one last weekend, should be still online *searching link* |
| 17:40 | Humpelstilzchen | paulk-aldrin: http://pastebin.com/KLBDhGjd |
| 17:40 | paulk-aldrin | [ 0.465979] imx-sdma 20ec000.sdma: loaded firmware 1.1 |
| 17:40 | paulk-aldrin | see |
| 17:40 | paulk-aldrin | mine says it didn't load it |
| 17:40 | paulk-aldrin | Humpelstilzchen, do you have an initramfs there? |
| 17:40 | Humpelstilzchen | paulk-aldrin: no |
| 17:41 | paulk-aldrin | how strange |
| 17:41 | Humpelstilzchen | initramfs is too complicated for me, so I don't use it |
| 17:41 | paulk-aldrin | well, it's not really necessary when root= is hardcoded |
| 17:41 | Humpelstilzchen | root= is passed by bootloader |
| 17:41 | paulk-aldrin | yeah |
| 17:42 | paulk-aldrin | but from the kernel perspective, it's hardcoded ;) |
| 17:43 | paulk-aldrin | jnettlet, got an explanation? |
| 17:43 | Humpelstilzchen | if you compile audio as module? |
| 17:43 | paulk-aldrin | well, SDMA is still going to be loaded too early |
| 17:43 | paulk-aldrin | hdmi-audio is not the problem itself |
| 18:20 | jnettlet | paulk-aldrin, an explanation of what? |
| 18:23 | paulk-aldrin | jnettlet, well, how come the SDMA firmware gets loaded with no initramfs and priori to mounting rootfs on Humpelstilzchen's cubox-i |
| 18:23 | paulk-aldrin | prior* |
| 18:24 | jnettlet | it is before it is mounted, or before it is mounted r/w? |
| 18:24 | jnettlet | regardless it is probably because the firmware is built into the kernel |
| 18:24 | jnettlet | but SDMA can load and then attach the firmware later |
| 18:25 | jnettlet | I would need to see the logs |
| 18:25 | paulk-aldrin | oh ok |
| 18:26 | paulk-aldrin | jnettlet, in my case, the firmware is on rootfs and the SDMA driver is loaded before the mmc is even probed |
| 18:26 | paulk-aldrin | hence, I cannot get it to work and HDMI audio fails |
| 18:26 | paulk-aldrin | or doesn't produce any sound at all |
| 18:27 | jnettlet | paulk-aldrin, I would need to see the logs, and also know the distribution. |
| 18:27 | paulk-aldrin | jnettlet, right, I don't have it here |
| 18:27 | paulk-aldrin | it's debian/jessie though |
