Hi Folks
Thanks for your very prompt replies.
I tried what you suggested.
I successfully booted from SD card (JP1 in) and tried both createmtdboot and
createmtdroot. Whilst createmtdboot and createmtdroot appear to work properly,
when I reboot back to the NAND flash (exit, power off, SD card out, JP1 out,
power up) I get the same hang issue.
I note that an asterisk '*' is printed during TS-BOOTROM process. The TS-7800
manual indicates that this is a"A bad block that was skipped over
(non-catastrophic)".
I've used several of these units without this issue.
