Trying to Bring up Kernel

http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/log/?h=imx_3.14.28_1.0.0_ga.

 

After Uboot logs I dint find any Kernel Logs then I implemented my own putc inside misc.c function to check whether uncompression linux is happening or not.

 

Uncompressing Linux... done, booting the kernel

 

I got the logs. But after that I am not able to get any early print logs.

 

Note:- I have enabled CONFIG_DEBUG_LL and EARLY_PRINTK.

CONFIG_DEBUG_LL=y

CONFIG_DEBUG_IMX_UART_PORT=2

CONFIG_DEBUG_LL_INCLUDE="mach/debug-macro.S"

CONFIG_UNCOMPRESS_INCLUDE="debug/uncompress.h"

CONFIG_EARLY_PRINTK=y

 

With the current definitions, I am able to see early print logs in 3.10 Kernel which i am running now on my board.

 

Kindly Suggest if i am missing out anything.
