MPC8313e-RDB booting problem

[robindev]

Hello,

I am trying to load and run a new linux kernel(the board contains kernel 2.6.20, and i try to boot the one from the BSP iso) on the MPC8313e-RDB (ver 4A, with PPC8313e), but i ran into some problem.

I have used the kernel from the images folder in the ISO. I have set up a TFTP server to load it in the board(in ram). I issue the following commands to load and boot the new kernel:

setenv ethact TSEC1
setenv bootargs root=/dev/ram console=ttyS0,115200
tftp 200000 uImage
tftp 1000000 rootfs.ext2.gz.uboot
tftp 400000 mpc8313erdb.dtb
bootm 200000 1000000 400000

the kernel seems to boots fine,but then suddenly the terminal becomes unresponsive. Most of the time this hapens when i do something with the ethernet controller, like ifconfig or ping(ping does not work, and always hangs the board)

am i doing something wrong?

i tried both ethernet devices

(used run run_vscld1 to load the firmware)

could it be that the  mpc8313erdb.dtb is for a different version of the board?

Thanks in advance!

this is where the board becomes unresponsive.

Robindev,

    I guess your problem is you donot run the vsc firmware .As I know ,The TSEC1's is connected to VSC switch and TSEC2 is connected to 88E111.What's more ,under linux ,the  ipaddr of the two  TSEC cannot  be the same netmask.

   You can run ifconfig to see the ipaddr of eth0 &eth1. If their netmask is same , you can try ifconfig eth0 down .

  If you want to use eth0 under linux ,you must first run the vsc firmware.

Robindev,

I'm not sure if this will fix the problem but it is worth a try.  One thing that was not shown in your trace was your uboot configuration as it was my experience that you had to be real careful about making sure all the environment parameters were setup properly and stored prior to booting.

In particular, one thing that gave me grief was in not setting the ramdisk_size environment variable.

During the normal process of doing an ltib build at the end there is often a message at the end of the build such as this example:

*******************************************************************

Your ramdisk exceeds the old default size of 4096k, you may need to set the command line argument for ramdisk_size in your bootloader allowing 10% free this gives 9504k . For instance, for u-boot:

setenv bootargs root=/dev/ram rw ramdisksize=9504

*******************************************************************

This is a warning message you need to take seriously and add the environment variable.  If you don't there are cases where linux will load and then crash when you try and run things in that the ramdisk is not large enough to even contain the set of files/programs created in the build process.

I got in the habit of setting the size to 128000 as there was usually still plenty of RAM left over for other things and this gave me enough size to allow most of my test software to be built without woring about running out of ramdisk.

Below is my uboot enviroment data I used on my board (this is an excerpt from one of my previous posts at:

Hi Alan,

I have tried your suggestion, but unfortunately it did not work. I think the downloaded iso is just not suited for the version of the board that I have. Too bad that freescale does not keep all the old board support .iso files available. I ordered a new(recent) board from freescale today, so I hope that the problem is solved that way.

Anyway, thank you very much for your swift and helpful reply! It maybe did not solve this problem, but it is certainly something that otherwise would have become a problem later on.

greets, Robin

I have put out a support request at freescale to provide me with the image of the correct cd, they provided me the download link within the hour. Now my problems are over. Guess i should have paid more attention to the version numbers... Annyway, thank you for your help!

Greets, Robin
