ICD-U64 EEprom problems 12f675
PostPosted: Mon May 25, 2009 8:52 am     Reply with quote

I have some troubles with storing data into the EEprom of a 12F675

CCloader does not accept the following instruction:
#rom 0xf2100={0x85}
According the CCloader File Info the file is CORRUPT.
Adress F2100 is out of range.

Other programmers don't have any problem with the Eeprom data table.
When I remove the #rom command I can program the controller without any problem.

What can I do?

You can try it by just adding the following command to your code
#rom 0xf2100={0x85}

Best regards,

Download the 12F675 Programming Specification from this page:

Look at this section on page 20:

4.3.2 EMBEDDING DATA EEPROM CONTENTS IN HEX FILE

What does it say is the EEPROM address ?

Hello
PostPosted: Tue May 26, 2009 1:11 am     Reply with quote

When the "f" is removed from the EEprom command the CCS Device Programmer accepts the command.


This works fine #rom 0xf2100={0x85} for a Galep programmer but the CCS Device programmer doesn't accept.

This works fine #rom 0x2100={0x85} for both the Galep and the CCS Device Programmer

What's the meaning of the "f" character?

Thank you for your help,

It is bits 16-19 of an address and it does not belong there.
The address is 0x2100, not 0xF2100.
