where, my FlashRead and FlashWrite functions will invoke the
functions defined in Xilinx BSP to transfer data from/into flash.
I do not know where the problem is...
You assume length % S25FL256S_PAGE_SIZE == 0.
Sorry, I should have read the code more carefully.
What is "beginning"? Why don't you use "offset" in this function?
