[nareshpuli]

HI,

 In the  SD Card i have U-Boot and Kernel images, its working fine  , When  i  keep in NxpP2020 Target Board is not Booting with the SD/MMC Card, My thought This is hardware issue pls help how can i fix this issue .bcz when i put in another Board is Booting...

In the console it shows like this

SD boot...
Second program loader running in sram...

The console log could indicate that the secondary program loader (SPL) is unable to properly initialize the DDR SDRAM - i.e. it is required to perform a memory test by means of a debugger or use CodeWarrior DDR Validation Tool.

Hi ufedor,

Thanks for your information,  You said the SPL is unable to initialize the DDR SDRAM ,but In the Target Board NOR Booting is working fine,

how can we say only DDR SDRAM issue

What does it mean "Target Board NOR Booting"?

Please use a debugger to check the processor state when the SD boot process stalls.

Target Board is NxpP2020, i am getting started with this is Board, How can i check the processor state.

Thoroughly check that the problem board has its configuration switches in identical positions as the working one.

Is the issue resolved?

Why you created two Technical Cases?

[nareshpuli]

Hi,

still it is not resolved, in the given link i  am not able to find DDR Tool, it is showing only codewarrior tools.

kindly waiting for your reply.

In the log:

> DIMM 0: is not a DDR3 SPD.

Try to swap DIMM modules between the working and the problem boards.

By establishing debug connection and examining the code being executed.
