| 16:33 | dbf> | Hello |
| 16:35 | dbf> | Trying to boot a hummingboard pro with a imx6 dual som but without emmc memory seems there is no path in uboot to do that |
| 16:40 | jnettlet> | dbf: which u-boot are you using? |
| 16:41 | dbf> | 2018.01 imx6 git branch |
| 16:42 | jnettlet> | okay, so that should be testing if emmc is present, and if it isn't it should set the some variant to be non-emmc |
| 16:42 | jnettlet> | do you have a u-boot command prompt on a serial console? |
| 16:43 | dbf> | yes seen it in the source, but got only black screen with old jessie image with 2015 uboot got picture and kernel errors about the emmc |
| 16:44 | dbf> | maybe this configuration never exists, i think hb was always with a som with emmc |
| 16:44 | jnettlet> | dbf: yes the old u-boot didn't have a way to detect if an emmc was present. I found a workaround for it and it is in the 2018.01 branches and mainline |
| 16:45 | jnettlet> | do you need to use jessie? I would recommend using our stretch images |
| 16:46 | dbf> | i would use a strech image but the stretch images dont work in this combination, only blackscreen no boot |
| 16:46 | jnettlet> | dbf: give me a couple of minutes. I will put together that combination and test. |
| 16:47 | dbf> | oh cool thanks :D |
| 16:47 | jnettlet> | you have a 1.3 SOM with the Broadcom wireless? |
| 16:47 | dbf> | yes |
| 16:48 | dbf> | with one antenne output |
| 16:48 | dbf> | must be the v1.3 |
| 16:49 | dbf> | oh my wrong is v1.5 |
| 16:49 | jnettlet> | it has the silver TI wireless on it? |
| 16:50 | dbf> | some silver WL18MOD next to socket |
| 16:51 | jnettlet> | yep. that is 1.5. We haven't sold a lot of those without eMMC |
| 16:51 | jnettlet> | I think I modded one for testing though. Let me look in my cases |
| 16:52 | dbf> | my fault there is a emmc 8g KLM8G IC is here |
| 16:53 | dbf> | sometimes better look under heatsink before writing |
| 16:53 | jnettlet> | dbf: okay then you do have an emmc |
| 16:56 | jnettlet> | regardless I just remembered that most likely your problem is that by default the stretch image does not come with a bootloader installed. We started to have so many boot options that we made it a second step. I just checked and our documentation is not very clear about that. I will fix that over the weekend :\ |
| 16:57 | jnettlet> | regardless. If you have an sdhc with stretch flashed onto it, you just need to add u-boot |
| 16:57 | jnettlet> | follow steps 5 and 6 on this page, of course changing the target device to whatever the sdhc card is on your host PC. https://developer.solid-run.com/knowledge-base/i-mx6-debian/ |
| 16:58 | dbf> | ok, in the image doesnt contain the bootloader anymore, i must flash SPL and uboot after it |
| 16:58 | jnettlet> | We have realized this is a bit tedious and are working on automating our image generation. |
| 16:59 | dbf> | i think i tried it yesterday and wondering about the different types of SPL and uboot files |
| 17:00 | dbf> | but try it now one time |
| 17:01 | jnettlet> | you can see they are named for the target device in https://images.solid-build.xyz/IMX6/U-Boot/ |
| 17:01 | jnettlet> | let me know how it goes, and I can get you a working image. I will take this into account when re-writing the documentation |
| 17:03 | dbf> | so sdhc is for external sd i think |
| 17:04 | jnettlet> | correct |
| 17:06 | dbf> | nop, dont boot |
| 17:25 | dbf> | tried everything from start : xz -dc sr-imx6-debian-stretch-cli-20180916.img.xz | dd of=/dev/sdd bs=4M conv=fsync |
| 17:25 | dbf> | dd if=spl-imx6-sdhc.bin of=/dev/sdd bs=1k seek=1; sync |
| 17:26 | dbf> | dd if=u-boot-imx6-sdhc.img of=/dev/sdd bs=1k seek=69; sync |
| 17:26 | dbf> | but dont work |
| 17:26 | dbf> | sdd is my sdcard |
| 17:44 | jnettlet> | and you don't have a serial console. Only HDMI? |
| 17:44 | jnettlet> | I will test |
| 17:44 | dbf> | in the moment yes |
| 17:45 | jnettlet> | okay. I have the hardware here |
| 18:05 | dbf> | any success ?? |
| 18:05 | jnettlet> | dbf: odd I replicated everything here and it booted as expected. What is even more curious is that you aren't getting any HDMI output. That should be enabled whenever the second stage of u-boot is run |
| 18:06 | dbf> | yes thats my thought too |
| 18:06 | jnettlet> | but this device boots fine with the older image right? |
| 18:06 | jnettlet> | and I assume it is fused to boot from SDHC |
| 18:06 | dbf> | yes with a jessie image it boots |
| 18:07 | dbf> | hmm it didnt fuse it |
| 18:08 | dbf> | IMX6U5DVM10 is the dual core or ? |
| 18:08 | jnettlet> | oh, then it may be falling back to recovery mode. We didn't have this functionality in the old u-boot yet so I believe it used to just try MMC |
| 18:09 | jnettlet> | Let me try and build you a quick hack for SPL, and see if that works for you |
| 18:23 | jnettlet> | dbf: hmmm I am replicating this but my patch isn't working. I will have to come back to this in a bit. I can get something working for you. Thanks for reporting the bug |
| 18:23 | dbf> | no i have to thanks for the help |
