ESPRESSObin v7 - Official BIONIC does not boot. HELP

Recommended Posts

Hi,

 

I have this latest ESPRESSObin v7 board. It doe's not boot official Armbian BIONIC. I have used Armbian before on other chips and I am pretty confident I am following the instructions correctly. Steps I did to get it going:

1. I followed official instructions to flash u-boot with bubt tool to it's latest version. My board is DDR4, 1GB,1 ram chip, 1000cpu,800ram. I got the right one - as all works just fine after a reset. Also applied relevant boot environment as instructed here https://www.armbian.com/espressobin/

2. I have then used etcher to burn SD card with bionic. Tried to boot - didn't work. Only getting call traces in kernel log.

3. I burned a flash stick and tried to boot from it over USB3 port - same result. kernel traces.

4. Just tried again with same USB - it all booted as i'm writing. I was greeted with linux login prompt. I thought all good. Then in 10 seconds after, without clicking anything - it failed with kernel error.

 

Full log attached below. Beginning of it you can see kernel log of a failed boot attempt. Then after I hit reset - you will see that it booted to login prompt as normal - and then shortly after it failed.

I have the same issue. Bought my v7 from Amazon. Like your board, my board says its 1000cpu and 800ram. I tried flashing it with the *correct*  firmware flash-image-ddr4-1g-1cs-1000_800.bin and got the same kernel panic issues. I then flashed it with flash-image-ddr4-1g-1cs-600_600.bin and it works fine. Problem is, it only runs at 300mhz per core. I'm returning my v7 to Amazon. I'll stick to my v5 until the bugs get ironed out.  Oh well.
