OK...
$ srec_info thingy.hex --intel
Format: Intel Hexadecimal (MCS-86)
Data: 000000 - 0173E3
300000 - 30000D
$ size ddplan.hex
text data bss dec hex filename
0 95218 0 95218 173f2 thingy.hex
So size is recording the 14 extra bytes of config data in the 300000 range
(and is in decimal). This is for a 96KB device - 98304 bytes - minus the
bootloader... It's getting tight!
Another bit of code I have (hexfile only - I think MPLAB generated) comes
out as:
Data: 000000 - 017F01
200000 - 200007
300000 - 30000D
F00000 - F003FF
And that's why size reports it being bigger than the device.
Thanks,
Gordon
