Error while programming pic18f4550 .

Hello

I am using student version of C18 Compiler v3.31 for pic 18f4550. The programmer which is used by me is Genius G540 programmer. when i load the hex file into the buffer , it gives the following message


" None configuration worde in the hex file"

"Please set it after loading"

what does it mean?

After that when i click the program button , only erase operation is successful , the blank,verify, program and encrypt operation gives the error.

Please tell me where i am doing wrong? i have already set the configuration bits of pic18f4550 in the programming software( Genius G540).

Regards

Simon

I do not have that programmer so this is a guess:

Most HEX files have the configuration fuses stored inside them. Normally they are at a reserved address which is outside the normal range for the device. The programming unit should read the data from that address and use it to configure the chip rather than store it as part of the program.

Either the configuration data is not in the HEX file or the Genius programmer is looking in the wrong place to find it. The message is telling that because it could not read the configuration from the file, you should set it manually.

Is it possible you have set the configuration in the assembler/compiler AND in the Genius software as well so it does not know which to use? It is best to embed the configuration in the assembler/compiler file if possible.

I have already set the configuration bits in the comiler/ software but i saw that there was an option of setting the config bits in the genius programming software also that's why i also set the same config bits as i set in the compiler but the error remains.
