Hi All

I am using the ST722F64G with Softec tool chain

I write a C program and debug it - all worked well

When I try to program the FLASH a message of no communication with device showed up (after programming process)

I didnt change any setup with the programmer software only load the S9 code and try to program

When I checked the ST7, the reset line was set to low

I have try to reset and re power up the device with no success

The 8MHZ Osc is working well but reset line stey low

Please help

Bobi

Hi Bobicat,

Difficult to get an answer on this frozen forum isn't it?

I don't handle the device your're using so I can just give you some ideas based on what I've already got with ST7LITE!

You have to check if your clock is running on your card. If not use the clock from the indart tool you're using.

Check that the supply (5V?) of your controller is not resetting during the debugging sequence before programming.

I suppose you use option bytes on this controller so check how your clock source is setted!

Good luck
