Leopard DM355 bootloader lost

This question is not answered

Hi,

I tried to load Ridgerun SDK with demo and during the first boot got a kernel panic and now the board is bricked.

First I tried to restore using the flash utility over /dev/ttyS0 as described in "How to bring back your bricked Leopard". It took a long time to complete -nanderase and then went in a loop.

Then I tried SD card flashing. I don't have a SD reader on my linux machine so used a USB adapter. formatted /dev/sdb and then mounted /dev/sdb1 to /media/disk and added boot data. Nothing happened when booting from SD card.

When I do minicom in UART boot mode I get "BOOTME BOOTME BOOTME ..."

How do I restore the uboot?

  • If you get "BOOTME BOOTME...", do a reset
