Pogo E02 - Wont boot to USB or Pogo OS (1 reply)

Working on a Pogo E02 now having got and V3 & V4 working. Upgraded UBOOT to latest version 2017007 as per instructions but now I can't boot to original Pogo OS or my Debian USB stick. This is the serial terminal dump:

If I manually start usb (usb start) the Sandisk 16GB stick is recognised as is the partition.

I have rummaged around but cant find anything obvious and I can't see anything on the WWW that has helped me so I'm asking the experts.

One other thing, when I copied the envs, I did see an error saying the env table was corrupt and it was using the default. When I look at the saved txt file, there is very little in it unfortunately. One other thing which I stupidly didnt make a note of is that my MTD partitions were laid out slightly differently to your default - I remember that it was the data partition which had a different start.

dev: size erasesize name 
mtd0: 00100000 00020000 "u-boot" 
mtd1: 00400000 00020000 "uImage" 
mtd2: 02000000 00020000 "rootfs" 
mtd3: 0??00000 00020000 "data"

I plan to check the Sandisk Ultra 3.0 in my pogo V4 tomorrow just to check the installation but as far as I can tell, it has no errors and is readable on my Zorin system and of course the mtd file is there.

Cheers - Bob
