Puzzles in the development of Nand Flash Driver under Wince 5.0
Guangliang via PocketPCJunkies.com
thanks advance for your assistance
The following is the detail for my case:
Platform: PXA270,
Os: Wince 5.0
FileSys: TFAT
NAND Flash:
Sector/Page Size:2048bytes;
Number of Sectors per Block:64;
Number of Block:8192
As the information above indicates, The total store space is 1G bytes(of
cause, from the memory storage menager, these indexs are all consistent with
that via the FMD_GetflashInfo) but I have never made full use of them. In the
tests, When I program about 300-500M bytes, the system would show me ECC
check error, and then, the whole file system would corrupt.
The Instruction of FAL in the 'help' doncuments is so scarce that I am not
availble to trace what happened.
(1)I have updated my PB 5.0 by the newest packs,what would the fal do next
when FMD_SectorRead return false(in other words, one sector read error)?
(2)How to judge wether memory overlap in the platform? I am sure that I have
appropriately fixed the FlashInfo Structure;
Thanks again for your attention, Any suggestion would be appreciated.
