Hi,
I recently updated my compiler from V3.249 to V4.099. Now I notice a difference in the HEX file:
V3.249

The first line is different, in V4.099 an extra line is added to the HEX file. I do not want that as my bootloader does not work with this format. How can I setup the compiler/builder not to add this extra line?
What means that extra line ?
best regards; |

The most recent version available for download is v4.090. I guess that is the version you have?

The hex file is in the well documented Intel hex format: http://en.wikipedia.org/wiki/.hex
Basically it is an extension to allow 32-bit addresses instead of 16-bit.

You took a short cut by implementing part of the protocol and now this is biting you. I'm sure Murphy hase a phrase for this...

Good question. I don't know, but as an alternative you can manually delete the line without problems. |

V4.099
What means that extra line ?
A standard data record only has a 2 byte address range. This additional record is the next most two significant bytes. The record enables the programmer (not just bootloader) to work out where the code is to be located including the program memory space, config registers and EEPROM.

Okay, thanks guys.
I also warned CCS support about this and they said the extra line is not necessary for PIC16 and it will be solved in next releases. |

As ckielstra pointed out, it is still a bug with your bootloader.
