Atmel ATmega 16 flash problem - Adi Tedjasaputra - May 28 10:28:00 2003
Dear listers,
My name is Adi Tedjasaputra.
I am in the middle of a boot loader development for Atmel ATmega 16 and I
encountered a flash problem.
The problem is related to the information storing. For an example: The
microcontroller manual wrote that I could address the max. of 128 different
pages (0x00-0x7F). I have no problem in accessing them, but when I write to
page 0x00 for example, the page 0x40 is also written with the same
information. I could test this behaviour by writing to page 0x00 and read
the information stored in page 0x00 and page 0x40 and vice versa. The
"mirror" boundary seems to range from 0x00-0x3F and 0x40-0x7F.
I wonder if anyone can help me solving this problem.
Thank you,
Adi Tedjasaputra -a-
