[ECOS] PXA250 lubbock flash memory question on RedBoot

[ECOS] PXA250 lubbock flash memory question on RedBoot

[Thomas Asami]

Hi,

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 have my flash at CS0, so redboot cannot find the valid flash at CS1.
Would anyone tell me and teach me what files I should modify?
Thank you very much!!

I assume there is a Lubbock eCos port somewhere, I do not see it in the eCos
CVS tree.

How/Where can I get it?

Thanks

Because I use my eval board, not Lubbock.

 Maybe I misunderstand the question but why not toggle switch
 S15 which swaps the nCS0/nCS1 chip selects.  Check the user's
 guide Flash/Boot memory section.
