how to read and write the data dynamically into the flash inside the 14583 chipset

Hi Dialog,

I am trying to make the program write and read the its own flash some sensor data into it. It always fail since the second time write into it, I verify the written data by reading it out again. Do you have some suggestion to fix the problem please?

My code is below:

unsigned char rd_data[256];
unsigned char wr_data[256];

unsigned short CRC16 (const unsigned char *nData, unsigned short wLength)
{

static const unsigned short wCRCTable[] = {
