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.
