We have ported several times, linux images in i.Mx28 processor based board and worked fine.
Now, all of a sudden started facing problem. We are not able to port completely.
Below messages are shown while porting:
"PowerPrep start initialize power...
Battery Voltage = 1.31V
No battery or bad battery detected!!!.Disabling battery
voltage measurements./r/nLLLCFeb 3 201801:20:37
FRAC 0x92925552
memory type is DDR2
Wait for ddr ready 1power 0x00820710
Frac 0x92925552"
After this, it is halting.
Because of what peripheral failure, it is happening?
What can be done?
Pl Suggest.
Hi lakshmi
if you are " not able to port completely" this may be hardware issue,
follow design checklist:

try baremetal OBDS test from link
Lab and Test Software (1)
On-Board Diagnostic Suit for the i.MX28

Hi igor
I have used cfimager & ported image to SDCard, but board is not able to detect SDCard.
I feel, Whatever ported is linux based OBDS.
Pl suggest, from where I can get bearmetal OBDS?
Thanks & Best regards.

Hi Igor,
Thanks for the reply.
Same link is already used, but board is not able to detect SDCard..
Please suggest any other means of identifying the root cause for the problem.
Can we conclude by seeing the messages where it is halting?
If available please send some document in which details about how to verify functionality of individual peripherals.
Thanks & Regards.
