Console apps are user-friendly matter of who their friends are ;)

Some examples should be helpful
http://home.mnet-online.de/al/BRAM_Bitstreams.html

There is also app for updating picoblaze code through jtag that also
could be useful after some modifications.

It would be nice if they supplied both GUI and command-line tools, but
if they're only going to do one or the other, I'd far rather have the
command line tool than a GUI tool. I can trivially invoke a command
line tool from my software Makefile, but it's a serious PITA to do
that with a GUI tool.

In my app, the data width is 1 bit, with 128k depth, that means I have
8 BRAM16 inst

---------below is my bmm file

ADDRESS_SPACE mem_module RAMB16 [0x00000000:0x00001FFFF]

BUS_BLOCK
XLXI_2/MEM_MODULE/BRAM_MODULE_INST/B76/RAMB16BWER [0:0] PLACED =
X2Y12;
END_BUS_BLOCK;

BUS_BLOCK
XLXI_2/MEM_MODULE/BRAM_MODULE_INST/B79/RAMB16BWER [0:0] PLACED =
X2Y14;
END_BUS_BLOCK;

BUS_BLOCK
XLXI_2/MEM_MODULE/BRAM_MODULE_INST/B82/RAMB16BWER [0:0] PLACED =
X2Y13;
END_BUS_BLOCK;


BUS_BLOCK
XLXI_2/MEM_MODULE/BRAM_MODULE_INST/B85/RAMB16BWER [0:0] PLACED =
X2Y15;
END_BUS_BLOCK;

BUS_BLOCK
XLXI_2/MEM_MODULE/BRAM_MODULE_INST/B88/RAMB16BWER [0:0] PLACED =
X2Y17;
END_BUS_BLOCK;

BUS_BLOCK
XLXI_2/MEM_MODULE/BRAM_MODULE_INST/B91/RAMB16BWER [0:0] PLACED =
X2Y18;
END_BUS_BLOCK;

BUS_BLOCK
XLXI_2/MEM_MODULE/BRAM_MODULE_INST/B94/RAMB16BWER [0:0] PLACED =

END_BUS_BLOCK;

BUS_BLOCK
XLXI_2/MEM_MODULE/BRAM_MODULE_INST/B97/RAMB16BWER [0:0] PLACED =
X2Y16;
END_BUS_BLOCK;

END_ADDRESS_BLOCK;


----below is the command line I try to see if I can extract the data
from existing bit file

$ data2mem -bm mybmmfile.bmm -bt existingbitfile.bit > log.txt

-------- But it always gives the below error

ERROR:Data2MEM:29 - Inconsistent address space size in ADDRESS_SPACE
'mem_module'.
ADDRESS_SPACE was defined as 0x00020000 bytes, but the
ADDRESS_RANGE total is 0x00004000 bytes.


---Then I try to change the address space to

ADDRESS_SPACE mem_module RAMB16 [0x00000000:0x000003FFF],

---It then gives no error but the log.txt file is just a blank,
nothing show up

---I wonder if this tool can't handle data width with 1 bit wide????

The tool doesn't have a clue. Just lie to it and tell it your RAM is
8 bits wide.

Okie, I can lie it about the address, but how can I "lie" it about the
data ?

Let me guess, I will have to tell it in byte, by concatenate 8 bits
together ?
