Lime2 power-up problem

[alexparser]

Hello

I have problem at power-up, every second start of board is failed.
The PSU 5VDC 1A work normally, I tested with two other PSU as well.
Also I try several different version of OS, but have same result.
How I can detect this problem?

Kind regards,
Alex

1A might not be enough, try a PSU with >=2A first before looking deeper.
