AT89S8252 has got 8kb Flash. I've programed for an application. hex file was created with 8.5kb (over) but my system still run well. I don't know why. Who help me?
A HEX file has a convention for representing a binary image in ASCII form which in and of itself "expands" the true binary size by a factor of >2. It happens to also include extra address, checksum, record type, start and end characters, etc. for each HEX "record".
The Linker Listing file (aka "Map" file) tells you the true size of code.
For BL51, it is .m51; For LX51, it is .map.
