imx287 boot failure

[adityapatil]

hi ,

1. I have a custom board designed with imx287 CPU

2. The NAND flash is MT29F1G08ABBDAHC-IT:D and RAM is MT47H128M16RT-25E.

I am getting the following Problems

1. If try to reset from " uboot > reset"  or do a power-up.

most of  the time board fails and i get the following LOG

MX28 U-Boot > reset
resetting ...

PowerPrep start initialize power...

Configured for 5v only power source. Battery powered operation disabled.

Hi Aditya

what about cold boot (not uboot reset), is it booting fine.

5v only power source mode is added with L2.6.35_1.1.0_130130 patch

Compile L2.6.35_1.1.0_130130 for i.MX28 on Ubuntu 13.10 64bit OS 

For new ddr support please look on

hi,

The cold boot is fine only for most of my custom boards but some custom boards I always get same boot failure output.

Thanks,
