    dear sjo,

    I have problem about ICP: as you know there is no need of isolation

    about ICCDATA and ICCCLK pin if these two pin is configured as output(decribed in the data sheet). But if I solder a blank chip on the board and begin to program with ICP and there are two LED connected with these two pin(include two 680ohm series resister. But I found I can not program the chip with ICP mode by using ST7-STICK. what is the problem? can I use FLASHBASH to program?

    best regards,

    The problem you are seeing is due to the open-drain communication method used for ICP.

    Flashbash should suffer the same fate as it uses the standard ICP protocol - but I have not tested it.

    dear sjo,

    I am making a prototype of FLASHBASH, but it is difficult for me to find

    the two parts ZVP3306 and ZVN3306 or the direct replacement of the

    two MOSFET. coudl you do me a favor to provide the requirements of the two MOSFET(Votage, Current, Rdson etc). I want to find the nearest part to use. Thanks your support.

    Best Regards,

    Really any kind of small mosfet is ok (parts are Zetex if you require data.

    ZVP3306 - also use BSS110

    ZVN3306 - also use BS108

    dear sjo,

    can I use FLASHBASH to program the board with 3V power supply?

    I know St7 Stick can do this?

    Flashbash has been tested down to 3.2v.

    Added Device Identifier support for ICC mode devices.

    ST7FLITES2/S5 bootrom modified, incorrect option byte address used.

    ST7265x programming possible with hardware watchdog enabled.

    Hi,

    But how one can build a FlashBash programmer without having pre-programmed uC? How can I obtain one?

    With regards

    Hello every body!

    I have realized 4 FLASHBASH programers.

    I can't have M25P10 memory, because ST doesn't manufacture them any more. I have M25P10-A. It doesn't work good!! I have a lot of problem to access the memory in PC mode or keyfob mode!!

    Is there anybody to help me?

    Thanks a lot,

    Malfrok.

    Could you explain your problem in a bit more detail, either M25P10 or M25P10A work with no problems in Flashbash.

    Just to keep everybody informed, I have just updated Flash bash to support RCCR calibration byte restoration after a device erase.
