Experience with K9F2G08U0M and SM262A with PC3K-Flash?

May 14th, 2009, 4:35

Got this 256mb SD card - could read the data but no automatic
detection with PC3K-Flash. Thought this one will be easy because
old 256mb - but .... (controller not included and tried several
alternatives - most probably the wrong ones....)

Would appreciate any information / about adjustments

thks

SMxxxx controllers almost always invert the data in the flash.

I use Soft Center flash tool, and it has a specialist SMxxxx utility, but don't know about PC3000 flash.

Surely PC-3000 Flash has SMxx algorithm, these controllers are very easy. Just perform bitwise inversion, see MBR/Boot shifts, FAT tables and analyse it.

In some cases I try recover SMxx chips, but data folders have red circles on folders, is this problem with my method, or utility (PC3K)? I can save result to image and run virtual translator and ammend shifts, this will usually get 100% data back, but surely there is something I am missing during the data mix removal?

With SMxx controller, sometimes the bank size is not consistant throughout the dump, so manual alterations have to be made to the under/over size bank sizes.

In soft-center there is a check_dir util you can run on the finished image to compare where folders should be and where they actually are in the dump. You can locate the address of first mis-aligned folder and it's error magnitude, then see which bank this pertains to and alter the bank size accordingly.
