Dear all,
My target board(CPU:IXP425, eCos template is GRG) with two flash chips.
Each one size: 16MB(Intel Strata Flash 28F128J3).
Memory mapping:
CS0->0x50000000
CS1->0x51000000
I'm using Configtool under Linux(packages:flash_v2-full-061008.tar.bz2),
then import /hal/arm/xscale/grg/current/misc/redboot_ROM.ecm
But the item FLASH device drives->Provide /dev block devices->Provide block
device 2, it's check box is empty.
Please tell me how to use flash_v2 to configure my target board? thanks.
Best Regards
Jack

You don't actually need to use the V2 FLASH code to support this setup
since the devices are the same and physically adjacent. Just edit
.../devs/flash/arm/grg/current/include/grg_strataflash.inl
and set CYGNUM_FLASH_DEVICES to (2)

Try using gdb to decode this string. It will tell you where it
crashed.

Hi Gary:
I'm modify
packages\hal\arm\xscale\grg\current\include\hal_platform_extras.h
like follows:
// 16MB Flash (Expansion bus CS0)
.rept 0x510 - 0x500
FL_SECTION_ENTRY __base,0,3,0,0,1,0
.set __base,__base+1
.endr
// 16MB Flash (Expansion bus CS1)
.rept 0x520 - 0x510
FL_SECTION_ENTRY __base,0,3,0,0,1,0
.set __base,__base+1
.endr
// Rest of Expansion bus (CS2-CS7)
.rept 0x600 - 0x520
FL_SECTION_ENTRY __base,0,3,0,0,0,0
.set __base,__base+1
.endr
The console display:
+$T0a0f:0000904c;0d:0000b2c8;#a8
Bets Regards
Jack

Did you remember to adjust the memory mapping to map in this
additional FLASH segment?

Hi Gary,
I'm modify grg_strataflash.inl, set CYGNUM_FLASH_DEVICES to (2),
then make "redboot.bin", and install it. Then reboot target board, but the
console display:
"+$T0a0f:0000904c;0d:0000b2c8;#a8"
Best Regards
Jack
