Mistakes after repairing of VoCore

Sat Feb 07, 2015 9:46 am

Hi, all!

Please help me with my troubles.

I am try to use uart cable and information from this link:
http://vonger.cn/?p=780

After soldering cable - I start VoCore and broke it.

Main reason - I used old information, but it marked same as my device - VoCore V.1.0

So I bought some parts at market and repaired VoCore.

Now my VoCore+Dock can not start.

Please check log's:

How I can find reason for this troubles?
How I can test SDRAM?
I try to find memtest in U-Boot but fail.

PS: Please remove wrong information from website.

Any ideas?

    U-Boot for VoCore(based on RT5350)Warning: un-recognized chip ID, please update bootloader!

I update that post, sorry for such trouble.

Your issue might be bootstrap problem. Read the sch and check if every pull up/down resistor is in right position.
Or connect every GND to real GND, and check if every cap is connected.

I usually get the OOM killer when the power is noisy or not high enough during the startup. Then VoCore detects only part of its memory, and it's either too little to start the kernel at all, or it just runs very slow and can't start any larger program.

Hi, all!

Sorry for long time answer. I found that reasine for this trouble is bootstrap pin's state.

So, I start my vocore without uart cable and now its ok!

Thank you!
