[microblaze-uclinux] Generating BSP in V2MB1000 h/w port of uClinux

[Shruti Patil <shruee@xxxxxxxxx>]

Hello,

I am extremely new to the concept of using an OS on an
FPGA, and have been trying to get a minimal uClinux up
and running on the Memec/Insight V2MB1000 board on
Windows platform. I found the hardware port in the
downloads section. This is the way I went about trying
to run an OS on V2MB1000 Microblaze board:

I unzipped the bsp package  and opened the system.xmp
file included in the hardware port in EDK 8.1.02

I ran "Generate netlist". I had to remove the ethernet
module from the design in order to skip over the
errors. After version updation changes and lots of
changes in .mhs file, I finally got to the "Generate
Libraries and BSPs" phase. However, I got the
following error that I am not able to understand (and
hence troubleshoot):

Done!



I donot know how to program using TCL script, but I
suppose that we can over-ride the " "" found instead
of integer" error by putting an if statement that
says: if "" found, then return a 0. Will this work? If
so, can someone give me the code to replace the
following code in the uclinux_v2_1_0.tcl file:

proc do_memory_setup {config_file os_handle
param_prefix config_prefix} {
.
.
.
	# Process memory core parameters
	set mem_start [xget_sw_parameter_value $mem_handle
$base_param_name]
	set mem_end [xget_sw_parameter_value $mem_handle
$high_param_name]

	# remove any embedded underscore characters
	set mem_start [string map {"_" ""} $mem_start]
	set mem_end [string map {"_" ""} $mem_end]

	# Format start_addr and size as hex strings
	set mem_start [format "0x%08x" $mem_start]
	set mem_size [format "0x%08x" $mem_size]



If I am thinking wrong and there is a problem with
setting the integer, then in which parameter (is it
highaddr, base addr?) should I set the integer that is
required by $mem_start parameter?

As a starter, all I want is to do a basic uclinux OS
to run on V2MB1000. If I am doing something wrong,
kindly give me instructions. Or if a good tutorial is
available that steps me through the design of EDK
program that will run uclinux on the board, then
please send me a link.

Thank you.

Regards,
Shruti
