You don't need to 'modify the driver'. The driver contains the routines to do
jobs like this. Just use:
Code:

_ext_flash_send(0x98,TRUE);

Hello,

I got it, now it's running well.

But one question left: why should I change FLASH_SIZE in the driver to 16777216? It's a 64MBit memory, so the size should be 64*1024*1024/8 (8 Bit = 1 Byte) = 8 388 608. According to the datasheet the max address is 0x7FFFFF = 8 388 607.

For an SST25VF080B the size should be 0x100000 = 1 048 576

8388607 sounds right.
I'm working with much larger memories... Smile
