Re: [microblaze-uclinux] Using different start address for System. map

[Paolo Pezzino <ppezzino@xxxxxxxxx>]

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)
