Thanks Paolo
But the problem is that these processors
use a shared memory and should have access to whole memory. The only thing is that
I want that their images start from different addresses (ex: 0x3000 0000 for Microblaze_0
and 0x3100 0000 for Microblaze_1) while the memory of both is 0x3000 0000-0x3FFF
FFFF!

Using different start address for System. map
Hi, salut du tessin...
I did like this in system.mss (EDK 8.x) (you can do it also using the GUI):
BEGIN OS
PARAMETER OS_NAME = uclinux
PARAMETER OS_VER = 1.00.d
PARAMETER PROC_INSTANCE = microblaze_1
PARAMETER lmb_memory = dlmb_cntlr_1
PARAMETER main_memory_bank = 0
PARAMETER main_memory = plb_ddr_0
PARAMETER stdin = RS232_Uart_1
PARAMETER stdout = RS232_Uart_1
PARAMETER main_memory_size = 0x10000000
PARAMETER main_memory_start = 0x30000000
PARAMETER TARGET_DIR =
/opt/uclinux-cvs-232/uClinux-2.4.x/arch/microblaze/platform/uclinux-auto/
END
BEGIN OS
PARAMETER OS_NAME = uclinux
PARAMETER OS_VER = 1.00.d
PARAMETER PROC_INSTANCE = microblaze_0
PARAMETER lmb_memory = dlmb_cntlr_0
PARAMETER main_memory_size = 0x10000000
PARAMETER main_memory_start = 0x20000000
PARAMETER main_memory_bank = 0
PARAMETER main_memory = plb_ddr_0
PARAMETER stdin = debug_module
PARAMETER stdout = debug_module
PARAMETER TARGET_DIR =
/opt/uclinux-cvs-mdm/uClinux-2.4.x/arch/microblaze/platform/uclinux-auto/
END
as you can see you should (it's faster and easier) use a different build
environment (i.e. a different directory) for every microblaze, so you'll end up
with a dedicated image.bin file for every processor

Hello All
I have a problem. I use multiple Microblaze processors with a
shared memory. ERAM parameters are same for all processors as below:
define_hex CONFIG_XILINX_ERAM_START
0x30000000
define_hex CONFIG_XILINX_ERAM_SIZE 0x10000000
After generating kernel (I use linux-2.4.x without MMU), System.
map of all processors start from same address 0x30000000 that is troublesome
for me.
I want to know how can I use another address range that are not
overlapping (ex: 0x30000000 for Microblaze_0 and 0x31000000 for
Microblaze_1)
