iMX53 boot failure

tpathan — Fri, 01 Aug 2014 20:54:16 GMT

Hi All,

On my target board after PoR the iMX53x DDR2 interface is not working.

The transfer of OS image on NOR to DDR2 is having an issue.

The CKE after PoR is always low whereas NOR bus activity shows up for few seconds and then halts.

System never boots. I am suspecting the iMX boot ROM code which initializes the DDR/NOR interface for OS transfer.

The board is production grade and was working fine before as intended.

Please share your views on how to confirm the issue.

Hi Tayyab

if this just one board and you nothing changed, then

this may be bad contact issue (probably due to inaccurate board

handling - bending or drop): one can resolder processor.

Additionally one can check 32.768KHz and 24 MHz clocks and all

power supplies.

Next step may be run OBDS (it can be run with jtag).

It has weimnor example

i.MX53 System Development User’s Guide (rev.1, 3/2011)

also describes main points for check

Tool for memory test

DDR_STRESS_TESTER_FOR_MX51_MX53 : DDR Stress tester kit for the i.MX51 and i.MX53.

Best regards
