problem with writing

Hi.

My program is written at F000-FFFFF.

i took flash api module from examples and trying to use it as follows:

1. Write string at D000 - Successfully

2. Read from D000 - Successfully, it means i got the written string

3. erase block 7 - Successfully

4. Read from D000 - Successfully, it means i got empty string

5. Write string at D000 - and i got Write Error reported by flash control register

Somebody has ideas why it can happens.

Thanks.
