[Buildroot] Olimex A20 Micro - freezing during boot up

[Buildroot] Olimex A20 Micro - freezing during boot up

[Kevin Golding]

Hello,

I've created a system based on the olimex_a20_olinuxino_micro_defconfig 
and I'm seeing it freeze at around 1.2 seconds during the boot up.

I'm a little worried about some of the errors during the boot such as 
"Failed to set core voltage! Can't set CPU frequency" & "*** Warning - 
bad CRC, using default environment" but as a complete newbie I'm not 
sure how important they are!

I've copied the serial capture below, and I would love to get my hands 
of someone's working equivalent to compare against, or any 
suggestions/advice?

Thanks,

Kevin

 When you say "based on", do you mean "equal to"? If not, go back to the
defconfig and check if that works. Don't hold your breath, though - see below.

 This is potentially harmful.

 This is quite harmless: U-Boot tries to read the environment from flash, but
it's not there (yet) because you never saved it.

 This looks potentially problematic. The AXP is the PMIC, i.e. the thing that
regulates the voltages to your CPU. If that thing is not working correctly,
things go very bad.

 It's even stopping in the middle of a printk...

 Smells to me like a hardware issue: insufficient current or possibly even
overheating. Do you have another board to test?

[Buildroot] Olimex A20 Micro - freezing during boot up

[Kevin Golding]

Thank you for the reply. You were right about the hardware, I got a 
second board and it boots up without those errors so my first board must 
have a fault on it.

Many thanks,

Kevin Golding
