i.MX6Q stopped during linux boot up

[xiaoqiangyang]

Hi everone,

My new desinged i.MX6Q board stopped during linux boot up. U-boot version is 2009.08 and bootargs setting as below:

......

nfsroot=/srv/rootfs

bootargs_base=setenv bootargs console=ttymxc0,115200

bootargs_nfs=setenv bootargs $ root=/dev/nfs ip=dhcp nfsroot=$:$,v3,tcp bootcmd_net=run bootargs_base bootargs_nfs; tftp uImage; bootm bootargs_mmc=setenv bootargs $ ip=dhcp root=/dev/mmcblk0p1 rootwait

bootcmd_mmc=run bootargs_base bootargs_mmc; mmc dev 0; mmc read $ 0x80

0 0x2000; bootm

bootcmd=run bootcmd_net

......

I boot the NFS filesystem but it stopped at--Freeing init memory: 208K ---,the boot log is as below:

Hi Xiaoqiang

you can try demo images below and not use dhcp

(use "ip=none" as kernel boot parameter)

Our usb hub is USB2514.And usb is supported in kernel configuration.

Hi Xiaoqiang

you can try demo images below and not use dhcp

(use "ip=none" as kernel boot parameter)

[igorpadykov]

do you mean that

without hub (remove USB2514 driver) board is running OK ?

Best regards

chip

[xiaoqiangyang]

no, with usb hub the board can run, but if use"ip=none" it can't run.

NO,

if I use "ip=none" as kernel boot parameter, the kernel stopped after this sentence "hub 2-0:1.0: unable to enumerate USB device on port 1";

if I use "ip=dhcp" as kernel boot parameter,the kernel passed dhcp section and stopped after "Freeing init memory: 208K",

our usb2514 is designed onboard and it seems that usb is not the real phenomenon. I think the real reason must be hiding behind them.

How do you see it?

[igorpadykov · Accepted solution]

I would suggest to remove USB hub completely from build and try.

"ip=none" "ip=dhcp" - do not remove USB hub from build.

[xiaoqiangyang]

I use "ip=dhcp" and modified my DDR3 configuration(not modified before) and finally boot up the linux. Thank you!

[controlhorus]

Hello

We are having the same situation here but I don´t find where the DDR3 configuration is made within linux. I only configured the u-boot ddr3 file.

Thank you

[xiaoqiangyang]

We are the same,we only configured DDR3 in u-boot.It seems like linux needn't to configure the DDR.

[controlhorus]

Hello.

It seems so. Just a while ago, I do what I had to do two days ago: run a network capture program on a third computer and see what is happening. My board is mounting the nfs root and doing some initial directory checking (i suppose) but when the file transfers start many of the board packets are not answered by the nfs server. So the load is really slow. I think the linux is starting but very slowly.

I am installing the root nfs in another computer to see if it goes better.

If anybody knows how to activate some debug-messages on the init process of linux to know what the init process is trying to do, I will thank that anybody. I looked for it but I was unable to found.

Thank you,

Jose

Hello

Here there were two things.

1) One line on the Ethernet connector was bad. After we correct it, speed was good but still nothing was being seen in console.

2) CONFIG_DEVTMPFS was disabled in linux configuration. We activated it, rebuilt and it started to print things in console.

Thank you,

Jose
