16f628 and 16ce625 difference for dejan hex?

[GSMWIZARD]

could somebody tell me why a pic 16f628 cannot be used, according to the data sheets they are very very similar.

instruction set is the same.<br />memory organisation is the same.

the only difference i can find is that the <br />16f628 has more data memory, and that shouldnt make no difference.

i hope to test the the dejan hex tonight on a 16f628 if it does not work then will try to rewrite hex to port over to a 16f628 <br />should be pretty easy.

will let all forum members know of results.

Hex for 16ce625 can't working on 16f628.

[beer33rus]

16ce625 used "i2c accessing" internal eeprom. <br />(Same as pic + internaly chip 24c02).

16f628 used on-chip eeprom with directly accessing. (same as 16f84)

To convert ce625 &gt; f628 you need dizassembly HEX and rewrite 2 proceures - write_byte_2_eeprom & read_byte_2_eeprom.

Hello!<br />I wrote the eeprom control rutins,and it's seems to work,because the dejan 103 sw is flashing,and counts the "updated phone"-s.With the original dev0.hex and with the hex,I wrote it's seems to work the sw update, at the end the sw write eeprom update OK.But it doesnt work,the phone can't find network, and makes stupid things.I can test only on a 3310 418.At the end of the procedure the program write the flash chk and cobba id.At programming the pic the pic must have the following data in the eeprom . 6byte-s : From 78h A5 5A 5A A5 00 00<br />With the flash chk and cobba id can I manualy write the checksum in the eeprom? What is the role of the eeprom.The "update-ed phone" count and a verify at beginning of dejan 103? Maybe not the eeprom control makes the mistake. Is there any other differencies betwen 16ce625 and f628. The eeprom control, I wrote seem to work, but the phone is not working.

i think the purpose of eeprom inside 16ce625 is to<br />store certain bytes from flash file and then calculation is done on i2c eeprom data to get faid.

this is just a theory.

I am working on conversation HEX for PIC16ce625 to HEX for PIC16F628<br />I want to find a good dissasembler.<br />This one doesn't work fine. As you see it didn't make labels 146-153. Why ? It says disasembler work bad.<br />Am I wrong ?
