Ok, I will try that. It is a good idea see if everything is working fine before going further. Thank you!

**Suriken** · 12-16-2016, 12:47 AM

That fixed crc error. Thank you.

I have other problem right now. I have a version of yocto which comes with a uboot which can be loaded in memory. No need of reflashing. I got it from voipac page I think).

Now I have a newer uboot through mfgtools without flashing spi, I tried the command boot with this image. And it works. it loads yocto through my uboot 2015 version.

Then, I thought I could do the same with a newer version of ubuntu/debian. And for that, I followed the next tutorial http://www.imx6rex.com/software/how-...3-15-and-3-16/
I used 3.15 kernel.
Everything went fine, I got the sd card with zImage, uImage (both in / folder) and every file I think it needs. But at the time of using "boot" command, I get this message: (filesystem is ext3/4 (both tested) as fat32 can't handle symlinks)

All "T"s start being an asterisk and they go increasing until count exceeds.

I see it tries imx6/zImage folder so I created one with that name and put inside both files. I got the same result.

Any ideas about this?

Did you use printenv /setenv / savenv to update the default env parameters according to your board?

**Suriken** · 12-18-2016, 11:05 PM

Um, I don't think so. I just did setenv to remove crc error. Also I tested some commands I found with "help". What should I modify with setenv/saveenv? My board is a imx6 rex pro 2gb.

**robertferanec** · 12-19-2016, 10:43 AM

In the environmental variables you need to setup some things about your board. For example, you need to setup where your kernel is located, where your filesystem is located, if you would like to boot up into display, what resolution, what interface, etc.

Here you have an example, it will help you:

Code:

setenv bootargs_mmc 'setenv bootargs ${bootargs} ip=dhcp root=/dev/mmcblk0p1 rootwait video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB666 vmalloc=400M fbmem=28M fbcon=28M'
setenv bootcmd_mmc 'run bootargs_mmc ; mmc dev 1; ext2load mmc 1 0x10800000 uImage-gpu 3916636; bootm 0x10800000'

**Suriken** · 12-22-2016, 02:54 AM

I have tested for the last two days and I got nothing. I am able to read the uImage from SD card and my kernel it seems to be loading but at some point it got stuck and never ends.

I tried with a couple of tutorial for creating the filesystem, different images of ubuntu/debian prepared for imx6rexpro and same result.

It could be related with the load of u-boot? I haven't flashed it yet. I am testing it through mfgtool program.

**robertferanec** · 12-22-2016, 11:20 AM

Could you attach the complete console output?

**Suriken** · 12-30-2016, 03:52 AM

This is the output as soon as I execute "Start" on MFGtools:

Code:

then, I execute:

The rest of the output from here:

In any of those 3 options, the code goes further.

I am not sure, but maybe this is the problem?

Code:

VFS: Mounted root (ext3 filesystem) readonly on device 179:1.

You may want to add 'rw' into your console command

Code:

Kernel command line: console=ttymxc0,115200 console=tty0 root=/dev/mmcblk0p1 rootwait video=HDMI-A-1:1280x720@60e

Maybe try something like this:

Code:

console=ttymxc0,115200 console=tty0 root=/dev/mmcblk0p1 rootwait rw video=HDMI-A-1:1280x720@60e

I am not sure if that is the problem, but that is what I would try.

I tried your suggestion but I get the same result. I don't know how to get through this because I don't see any error message on the console output and I can't execute commands because it gets stuck there.

Could it be a failure in my sd card? Maybe I am copying the image/compiling the kernel in a wrong way. Or I should change any option while compiling kernel. I compiled it with the options it had by default.

**robertferanec** · 01-02-2017, 01:26 PM

How do you change the linux kernel command line? Because it looks to me like it is not changed. I see, that you run in uboot "setenv bootargs console=ttyS0,115200 root=/dev/mmcblk0p2 rootwait panic=10 ${extra}", but in the kernel I see "console=ttymxc0,115200 console=tty0 root=/dev/mmcblk0p1 rootwait video=HDMI-A-1:1280x720@60e". Have you double check if the kernel command line is really changed?

**Suriken** · 01-03-2017, 02:36 AM

Actually, I don't. How can I check that? But, if I execute setenv.... command, it is supposed to update that, isn't it? Maybe that is the problem here.

what can I do if that line is not updated?

**robertferanec** · 01-04-2017, 05:28 PM

But, if I execute setenv.... command, it is supposed to update that, isn't it?

It depends ... depends how you compile kernel. Some kernels may have the command line compiled in and it may not be possible to change it from uBoot.

**Suriken** · 01-09-2017, 11:49 PM

Damm it, I am so lost here...

I compiled 3.15 kernel I found in this repository http://www.imx6rex.com/software/how-...3-15-and-3-16/ (it is the one provided by fedevel in this tutorial: http://www.imx6rex.com/software/how-...3-15-and-3-16/). They say that 3.16 is bugged and it is better 3.15.

Apart from that, debian image is taken too from that webpage, ported by Sam Nazarko.

I compiled kernel with its default parameters:
on console:

Code:

sudo ./build_kernel.sh

wait until it loads and then click on exit (to leave all the option as they were).

On the bottom of that tutorial webpage, I read this:

Code:

[COLOR=#373737][FONT=&quot][SIZE=15px]2. Because the new kernel cannot pass the parameters set in u-boot they need to be compiled directly into the kernel. Open defconfig file:
...[/SIZE][/FONT][/COLOR] 
[COLOR=#373737][FONT=&quot][SIZE=15px]Look for [/SIZE][/FONT][/COLOR][I]CONFIG_CMDLINE[/I][COLOR=#373737][FONT=&quot][SIZE=15px] parameter. If you for example want to boot from hard drive you will change it to:
...[/SIZE][/FONT][/COLOR]

the line which comes with the file is:

Code:

CONFIG_CMDLINE="console=ttymxc0,115200 console=tty0 root=/dev/mmcblk0p1 rootwait video=HDMI-A-1:1280x720@60e"[COLOR=#373737][FONT=&quot][SIZE=15px][/SIZE][/FONT][/COLOR]

Here is where we are supposed to change the cmd line. I want to boot from my microSD. It is the first one (dev board has 2 slots). What should I write here?

After this change, should I set in somewhere else a line to get uImage by default instead of load it by commands? If I wanted to load it by default as soon as the system boots up.

**Suriken** · 01-11-2017, 12:09 AM

Ok, I have found a file on uboot folder under: /include/configs/mx6rex.h

This file contains multiple configuration lines, like: CONFIG_ENV_DEFAULT_IMG_FILE, FDT, SCR, ETH, CLIENT...

Part of the list:

Code:

/* Env settings */
#define CONFIG_ENV_CONSOLE_DEV              "ttymxc0"
#define CONFIG_ENV_MMCROOT                  "/dev/mmcblk2p2"
#define CONFIG_ENV_DEFAULT_UBT_FILE         "u-boot-" CONFIG_REX_DEFAULT_ARCH_PREFIX "-rex" CONFIG_REX_DEFAULT_ARCH_POSTFIX ".imx"
#define CONFIG_ENV_DEFAULT_IMG_FILE         "zImage-" CONFIG_REX_DEFAULT_ARCH_PREFIX "-rex" CONFIG_REX_DEFAULT_ARCH_POSTFIX
#define CONFIG_ENV_DEFAULT_FDT_FILE                   CONFIG_REX_DEFAULT_ARCH_PREFIX "-rex" CONFIG_REX_DEFAULT_ARCH_POSTFIX ".dtb"
#define CONFIG_ENV_DEFAULT_SCR_FILE         "boot-"   CONFIG_REX_DEFAULT_ARCH_PREFIX "-rex" CONFIG_REX_DEFAULT_ARCH_POSTFIX ".scr"
#define CONFIG_ENV_DEFAULT_ETH_ADDR         "00:0D:15:00:D1:75"
#define CONFIG_ENV_DEFAULT_CLIENT_IP        "192.168.0.150"
#define CONFIG_ENV_DEFAULT_SERVER_IP        "192.168.0.1"
#define CONFIG_ENV_DEFAULT_NETMASK          "255.255.255.0"
#define CONFIG_ENV_DEFAULT_TFTP_DIR         "imx6"
#ifdef CONFIG_SYS_MMC_ENV_DEV
#define CONFIG_ENV_MMC_ENV_DEV              __stringify(CONFIG_SYS_MMC_ENV_DEV)
#else
#define CONFIG_ENV_MMC_ENV_DEV              __stringify(0)
#endif

My image is called uImage. This the one I load by commands before call bootm. Should I modify this file? WHat should I set? Anything else? MMCROOT?
