[ECOS] HELP!! RedBoot problem

[K. Young Park]

Lubbock (code name for the PXA250 Dev. board) has two flash memories. One at CS0 and the other at CS1.
The original Intel RedBoot code uses the second flash at CS1. I guess you have your flash at CS0, so redboot cannot find the 
valid flash at CS1.
You need to change two points.
1. hal/arm/cotulla/lubbock/current/include/hal_platform_setup.h (The path may differ depending on your redboot version)
-> Change MMU Mapping so that your flash at CS0 is mapped to the virtual address you want.

2. devs/flash/arm/lubbock/current/include/xxx.inl (The path may differ depending on your redboot version)
-> Change CYGNUM_FLASH_BASE to the virtual address you specified in the hal_platform_setup.h

That's all.
Good luck.

Hi,

After running RedBoot on a pxa250 platform, I got
the following messages:

+
ARM eCos

RedBoot(tm) debug environment - built 15:49:04, Mar 27
2002
Platform: Intel(R) DBPXA250 Development Platform
RedBoot* Debug Monitor ()

RAM: 0xa0000000-0xa4000000
Can't identify FLASH, sorry
FLASH: driver init failed!, status: 8
LAN91C96: Unable to detect device - upper 8 bits = 202
Can't get BOOTP info - network disabled!
RedBoot>

Does that mean that my pxa250 platform's flash layout
problem? Cotulla has 64M flash and sdram, my board has
32M flash and SDRAM, what files I should modify? Please help me,
thank you very much!
