Hi,

Does anyone know how to enter ICC mode with ST72F623 family?

I have tried to enter ICC mode in ''256 tcpu fixed window mode'', which is based on ICC protocol manual. But I couldn't enter ICC mode successfully. I have no idea now.

I used VPP pin for ICCSEL and sourced 4MHz frequency to OSC1 externally.

Properly sourced 38 pulses on ICCSEL pins (H2L) after RESET mode, which is that RESET goes high.

Maybe the period of 38 pulses are not short enough within 256 tCPU window under 4MHz external clock?

or Should I enter ICC mode through ''Controlled Windows mode''?

I tried this as well. Doesn't work either.

Am I missing something?

So .... I'm stuck now.

Please help me on this. :-[

Thanks!

Are you writing your own programmer then, this is the only time you would need this info.

Have a look at the Flashbash source code where you will find an example of entering programming mode for this device.

look in the file icc.asm and the function ICCEnterFixed.

Finally I was able to enter ICCMODE in 256 fxied window mode.!!!

Thanks a lot for the reply!!!

By the way,

Even thoguh I loaded my own flash programming code into RAM, I could not program HD flash.

I applied proper VPP of 12V voltage during program stage.

I'm just curious whether the device supports the Embedded Commands for HDFlash programming, which is an area of F8 ~ FF??

Does anyone know if the ST72F623F2 supports the HDFlash programming commands?

Thanks!

See DFU examlpe f/w based on 7263 to take idea of HDflash prog
