pk2cmd + pic18f4550

[august black]

Hi,

        I was wondering if anyone has had any experience using the pickit2
        and pk2cmd under linux?   I just got one, thinking I could program
        my device [http://www.create.ucsb.edu/~dano/CUI] in circuit.   I
        connect the pickit2 to the board using a cable I built , and double
        and triple checked the connection.  I can do:

        >>>pk2cmd -PPIC18F4550 -I
        >>>Device ID = 1202

        and ...I see that the device is connected.   But, when I erase and
        then check the memory, it always says:

        >>>pk2cmd -PPIC18F4550 -E
        >>>Erasing Device...
        >>>Operation Succeeded
       
        >>>pk2cmd -PPIC18F4550 -C
        >>>Configuration memory is NOT blank.

        >>>Address   Good     Bad
        >>>300000    000500   000000

        >>>Operation Succeeded

       
        I don't understand the output.   It says the operation succeeded, but
        prints out memory errors.   Ultimately, I cannot write a .hex file to
        the device.

        Does the latest pk2cmd 1.12 with the 2.32 firmware work under linux?
        Any suggestions?

        many thanks - august.

If you can not get the answer here, maybe you can try
pickit-devel group.

It should work.

mcuee@Ubuntu804:~/Desktop/build/pk2cmd/pk2cmdv1.12.0$ ./pk2cmd -?V

Executable Version:    1.12.00
Device File Version:   1.52.00
OS Firmware Version:   2.32.00


Operation Succeeded


mcuee@Ubuntu804:~/Desktop/build/pk2cmd/pk2cmdv1.12.0$ ./pk2cmd -PPIC18F4550 -I
Device ID = 1202

You may need to add a cap between Vdd and Vss.
http://forum.microchip.com/tm.aspx?m=270347&mpage=2 (Post 25).

The "Operation Succeeded" just means the program returns properly. It does
not really mean the intended operation is correctly finished. Maybe we should
ask the author to change it.

Xiaofan,
       
                Thanks for the reply.

                I was able to test on another board and got it all to work.

                There must be something wrong with the one chip that I have.

                thanks -august.
