Reading files by fread and fseek

Your question isn't quite clear to me, but your code does the following:

Loop 5 times:
fseek with SEEK_SETsets the file position to 35 from the beginning of the file.
fread reads 7 bytes from that position.

If you intend to read the first 35 bytes, you can just do:

fread(u8Buffer, 1, 35, fp);

It would help if you specify how many bytes you want to read from which position in the file.

You are using fseek() within the loop so that the file position is always set to the same position before reading. That results in reading the same data 5 times.

You have to update the seek position too:

for(i = 0; i < 5; i++)
{
    fseek(fp, u32FilePointer, SEEK_SET);
    u16BytesRead = fread(u8Buffer, 1, 7, fp);
    // The read updates the internal position of the file pointer
    // If we want to track the position we have to do it also for our variable
    u32FilePointer += u16BytesRead;
    // Or use ftell() to get the internal position
    //u32FilePointer = ftell(fp);
    printf("u32FilePointer : %lu\n" ,u32FilePointer);
}

When reading should always continue after the last read data, you can also move the seek() out of the loop:

fseek(fp, u32FilePointer, SEEK_SET);
for(i = 0; i < 5; i++)
{
    u16BytesRead = fread(u8Buffer, 1, 7, fp);
    printf("u32FilePointer : %lu\n", ftell(fp));
}
