RE: [microblaze-uclinux] Questions on auto-config build flow

["David Banas" <dbanas@xxxxxxxxxxxxxx>]

Thanks, John. With that help, I was able to make quite a bit more progress.
I now seem to have a parameter getting picked up somewhere that's too big,
as per:

----------- Build output begins here. ----------------------
Running generate for OS'es, Drivers and Libraries ...
#--------------------------------------
# uClinux BSP generate...
#--------------------------------------
drvlist : 35697028 35654384 35663344 35663904

ERROR:MDT - ERROR FROM TCL:- uclinux () - integer value too large to

       while executing
   "format "0x%08X" $param_value"
       (procedure "xprint_params" line 25)
----------- Build output ends here. ----------------------

Here's the 'opb_gpio' section from my 'system.mhs' file:

---------------- system.mhs file excerpt begins here. -----
BEGIN opb_gpio
 PARAMETER INSTANCE = opb_gpio_0
 PARAMETER HW_VER = 3.01.a
# PARAMETER C_BASEADDR = 0xFFFF_7000
# PARAMETER C_HIGHADDR = 0xFFFF_71FF
 PARAMETER C_BASEADDR = 0xFFFF7000
 PARAMETER C_HIGHADDR = 0xFFFF71FF
 PARAMETER C_GPIO_WIDTH = 32
 PARAMETER C_IS_BIDIR = 1
 BUS_INTERFACE SOPB = opb_v20_0
 PORT GPIO_IO = led
 PORT OPB_Clk = sys_clk
END
---------------- system.mhs file excerpt ends here. -----

As you can see, I had to correct a couple of hex values that had been
entered strangely (not sure why; I didn't create this file.), in order to
get this far. I don't see anything in this section that looks like it's
larger than 32 bits, do you? Any thoughts?

Thanks again for all the help,
