Hi all,
I am trying to embed QNX6.2.1 on a PowerPc 7447A board. I am
working with Sandpoint BSP from QSS,
I want to understand how to specify board memory map in the
init_asinfo.c . Specifically how to specify my ram addres space and the
peropheral address space which includes a serial controller for which i
have already written the callouts.
Memory Map for my board:
SDRAM MEMORY
Start address: 0x00000000
End address: 0x1FFFFFFF
Size: 512Mbytes.
Boot Flash Memory
Start address: 0xFFF00000
End address: 0xFFF7FFFF
Size: 512Kbytes.
User flash Memory
Bank1
Start address: 0x78000000
End address: 0x7BFFFFFF
Size: 64Mbytes
Bank2
Start address: 0x7C000000
End address: 0x7FFFFFFF
Size: 64Mbytes
