linux3.1 with mxs_defconfig hangs up when booting the kernel

Dear all,

 

 

I am trying to get an i.MX28 EVK board running with a 3.1 kernel compiled with buildroot.

To start the linux kernel, I am using the Freescale ROM bootloader as provided by the buildroot mxs-bootlets package.

For the kernel, I am using the standard mxs_defconfig config file available in the 3.1 kernel.

 

 

When trying the boot the bootstream from USB via the sbloader tool, the kernel seems to hang at kernel booting:

PowerPrep start initialize power...

LLLLLLLFLCLLJUncompressing Linux... done, booting the kernel.

 

 

I have seen on several posts on this forum that such issue could be related to serial interface name. I specified in the kernel boot arguments the use of ttyAMA0 but this does not solve the issue

 

 

Would anyone have get a 3.1 kernel with the mxs_defconfig config file running on the iMX28 EVK?

Would anyone already have faced such boot problem?

 

 

Many thanks in advance for any answer.

 

 

Best regards

 

Adrien
