A20-OLinuXino-LIME does not boot from SDHC

[syntax3rror]

Hi,

I downloaded the Debian image for the A20-OLinuXino-LIME, decompressed it and wrote it to a 16 GB SDHC memory card (yes, I know, this might look like a waste of space).

I tried to boot the A20-OLinuXino-LIME but it only showed a yellow LED flashing near the power jack. However, my A20-OLinuXino-MICRO-4GB I usually use with the SDHC card with preinstalled Debian could boot from the 16GB SDHC card I just wrote.


Do you have any ideas what I could be doing wrong?

Hi,
we 've already open a thread on this point.
The solution I found to handle tis problem is, boot without your SD card, and wait until android boots.
Then insert your sd card and press reset.
I don't know where this problem comes from, but to me it fixes the problem.
Hope it will help
Best regards,

This is hardly an option since I have the board without NAND memory which means: without Android.

Sorry so, I can help, but I would be interested by the way you will fix that.

I am afraid it cannot be fixed. I ordered the wrong power supply (12V). When I noticed this was a too high voltage I ordered the right one but meanwhile tried to boot the A20 LIME using the power supply from the A20-Micro which I thought to be rated at 5 V as  well.

Right now I noticed this was wrong :-(

I ordered another A20-OLinuXino-LIME from Amazon this time and used the 5V power supply. However, it showed the same problem and could not boot the image. Only the yellow LiPo-LED was flashing.


For me, the A20-OLinuXino-LIME is at the moment an completely useless crap where I am unable to run anything on it.

This sucks! Sorry guys.

Time to measure the actual voltage of the power supply as it sounds like you fried one or both boards.

The -MICRO doesn't look to use 5V PSU.

I probably fried the first board which I used wit the power supply of the -MICRO. I used the second -LIME only with the 5V power supply I bought from Olimex.

It's something else you're doing wrong, then.  Use a serial port for the console to see how far it gets.  Or use FEL mode.  Or ... any of the standard ways covered for AW devices here & on the various wikis.

I had the same LiPo LED issue. I changed the power supply(5V/1A) with a better one(5V/2.5A) and it was fixed.

I just noticed Olimex released an updated Debian-Linux image (a20_Lime_debian_3.4.90_release_2.img) which worked like a charm. On both devices (one of them I was afraid to be fried)


Thank you very much!
