Title: U-Boot SPL DRAM:Timeout initialising DRAM
Post by: Zaxter on May 18, 2015, 06:51:26 PM

I'm having problems trying to get my A20 to boot.

I get the following on my debug UART:

U-Boot SPL 2014.04-10706-g36080eb (Aug 19 2014 - 16:42:16)
Board: A20-OLinuXino_MICRO
DRAM:Timeout initialising DRAM

resetting ...

.... (Repeats infinitely)

Could anyone help me?

Wrong or bad image or SD card. Maybe a bad PSU.

Hey,

What is your board? Are you using the default image from the wiki article of your board?

Download a fresh copy of the latest image for your board and prepare a microSD card. Ensure that you are getting the correct image. Test with Android.

Use external power supply to power your board - powering the board from the mini USB is not always reliable and sufficient. Parts of the hardware might remain under-powered (like the RAM memory in your case).

Best regards,
