Hi!

This is still strange. I never got any of those errors. Just to be
sure it's not another type of mistake:

- the patch is against UrJTAG 0.9 source files as they can be
downloaded from their site;
- the TS-7800 is correctly functioning and you are not using NAND or
SD card for any of the mounted file systems;
- the SVF was generated with Lattice tools.

In my case, I have an USB flash and I have changed the NAND initrd and
kernel command line to use the USB flash for root. The NAND partitions
are not mounted at all. Info on how this could be done will come
rather soon.

In Lattice tools, just in case, the steps to follow are:

- generate bit stream
- use ispVM tool for converting bit stream to SVF

In the ispVM tool the Universal File Writer should be used. The .bit
file should be first converted to .isc and then the .isc file to .svf.

Sometime in the future I might write a tool to get the .bit file
written directly for the TS-7800 JTAG chain. Right now such approach,
from my point of view, is premature until I prove myself that the
board is adequate to my needs.
