I have a problem with a custom i.MX287 board, based on Freescale EVK. It is using 5V only connection scheme with no battery present, and booting from an SD card. The same image is booting fine in EVK. Boot process goes fine until the Linux should boot up. Then the processor reboots endlessly. Debug data from DUART given below:



PowerPrep start initialize power...


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

memory type is DDR2

                    Wait for ddr ready 1power 0x00820616

Frac 0x92925552

start change cpu freq

hbus 0x00000003

cpu 0x00010001

start test memory accress

ddr2 0x40000000

finish simple test



The next thing that should appear, is "Uncompressing Linux", but it never appears. The operating voltages seem to be at correct levels and stable.


Thanks in advance,
