Hello everyone,
I am using LPC1788 with Keil RTOS and done nand flash interface to write several .txt files in it , and i have written it properly by creating folder . Now i have faced the issue like after some files written , my none of new .txt file cant be written in nand flash why is this happening? After debugging i have checked that it gives me success response after file written in nand flash , it shown me in directory after directory read,but after opening file it gives me blank data why is this so? somebody please explain me and how to solve this issue?because my previous data written in nand flash is all fine and shown me ok.
Waiting for reply. Thanks

Review the data sheet for your NAND device very carefully, then analyze and log your interactions with the NAND device. You might do this through instrumenting your code, or using a logic analyzer on the pin interface.
Pay particular attention to the commands and status reported by the NAND device during your read, erase and write sequences. Review how you manage large erase blocks, and the adding or changing smaller blocks of data within them.
