Nand flash of WinCE 5.0 CETK

#1 08-11-2008, 03:36 AM

Hi all,

Could anyone tell me which item the NAND flash should be tested in WinCE5.0
CETK? "Flash Memory Read/Write and Performance Test" only?
I want to test the NAND of "Flash memory read/write and performance test",
it always fail in "create file error". Could anyone give me some suggestions?
Thank you in advance.

Hi HPChen,
As i know, the "Flash Memory Read/Write and Performance Test" is not for
NAND flash but for flash memeory. And i think you can write a CETK test case
focus on NAND flash performance.
thanks

Thanks for the reply.
It means that WinCE 5.0 CETK can't test the NAND flash. right?! If I want to
test NAND, I should write a test code by myself?!
Thanks a lot.

What do you think NAND is? It is flash memory, just like NOR flash is flash
memory. The test works on a block device, and it doesn't even need to be
flash. It just exercises the block device in a way that can expose common
problems on flash based implementations.
