Re: [microblaze-uclinux] mbvanilla GPIO pins

[Johan Bernspång <johan.bernspang@xxxxxx>]

As you can see in the system.ucf file in the /data directory of the 
mb_vanilla project the 24 GPIO pins are connected to 2 seven-segment 
LEDs, a single LED and 8 DIP switches. These are available on the 
hardware platform from Memec that mb_vanilla originally is targetted 
for. My guess is that your hardware platform has some sort of these I/O 
stuff, but you have to adjust the GPIO to handle them correctly. Also, 
check the documentation for your hardware to find out which pins the I/O 
stuff are connected to.

As for the UARTs, the console UART is used for the communication with 
the terminal that you use to controll the linux system (the shell). The 
debug UART is used together with XMD to debug the system. That is, if 
you just want to run the linux system you can remove the debug UART. 
It's been a while since I was working with this project, but I think you 
should be able to use the JTAG UART for debugging purposes, but someone 
else has to confirm that.

Cheers
Johan
