Sir,
I have to port eCos on a new platform with processor
MPC860P (powerQUICC). I am using the Âmbx package as
the base. The memory layout of my board is like this:
THE MEMORY MAP OF MPC860P BOARD
ChipSelect Memory Type Address(hex)
Data Bus Bank Size
CS0--------------- FLASH-----------------------F800
0000 -F9FF FFFF----32 Bit ---------16Mbyte
CS1 --------------external register bank---0000 0000
-F000 FFFF-----32 Bit----------64Kbyte
CS2---------------external packet FIFO----F100 0000
-F103 FFFF-----32 Bit----------256Kbyte
CS3---------------SDRAM----------------------0000 0000
-07FF FFFF-----32 Bit----------64Mbyte
CS4-7-------------Not
used-----------------------------------------------------------------------------------
-----------------Internal CPU memory------FF00 0000
-FF00 FFFF----32 Bit-----------64Kbyte
I changed Âthe mlt_powerpc_mbx_rom.ldi to
Âmlt_powerpc_newmbx_rom.ldiÂ, and this is the file
what I made, at present I am only considering the
ÂRAMÂ & ÂFLASH (ROM)Â
--------------------------------------------------------------------------------
#include <cyg/infra/cyg_type.inc>
MEMORY
{
ram : ORIGIN = 0, LENGTH = 0x8000000
rom : ORIGIN = 0xf8000000, LENGTH = 0x2000000
}
SECTIONS
{
SECTIONS_BEGIN
SECTION_sdram (ram, 0x00000000, LMA_EQ_VMA)
SECTION_miniboot (rom, 0xf8000000, LMA_EQ_VMA)
SECTION_application (rom, ALIGN (0x4), LMA_EQ_VMA)
SECTIONS_END
}
----------------------------------------------------------------------------------
One more thing as Âconfig tool v2.11Â is not having
the MLT editing tool, so I am using the
Âv.3.net for editing the MLT file. But after editing
and saving when I again open the file the
MLT window shows me its default layout not the new
layout what I made.
Actually on my board ÂMiniboot is already there, so I
thought to place ÂREDBOOT.srecÂon
ÂMinibootÂ(as miniboot is able to load Â.srec files).
Is it ok? or I have to replace miniboot by
redboot.
When I ported the Âredboot.srec on it, the miniboot
started giving error like
ÂUnknown commandÂ
While creating redboot for my Ânewmbx package I am
getting one more file Âredboot.ppcbugÂ. When I port
this file to miniboot, it downloads it successfully
but it does not run the image.
I am doing so many experiment to port eCos on this
board. Before this I ported redboot on x86,
which was done successfully. Because there I need not
to create a new package for Âx86pcÂ. But here in case
of MPC860P, I am not sure whether the new package what
I create is correct or not.
Please help me out.
Thanks & regards,
VENKAT KUMAR ANDE
