RE: [microblaze-uclinux] Microblaze4 slow kernel download with XMD

Aloha,
It seems you have a problem with the cable or printer port.

| I use dl.sh script for download, and xilinx parallel cable IV in 
| compatibility mode (cable III mode) in Linux.

Why compatibility mode?  Did it use to work in fast mode?

| The download time was 1min with Mb3 design versus 4min with 
| Mb4 design! 

You are working at 200kHz in compatibility mode vs 5MHz in PCIV fast mode.
It should take longer.

Above it seems it finds ECP hardware, but the driver is AWOL

Here it doesn't find the ECP hardware.  Something is strange with the
hardware or a bug in the impact software.

Sorry I can't tell you exactly what you need to fix it, but those are the
clues I see.
