Prevent erasing EEPROM during compiling

[Jan Lichtenbelt]

This there a possibility to prevent erasing the EEPROM during compiling the flowcode and laoding the program into the PIC, by e.g. changing the (PPP) paramters?

Hi Jan

This should help...

PPP V3 options allows to choose between erasing PIC micro before programming and a check on it.
I removed these options and close the windows with OK. Opening the PPP window again shows that my choosen options were removed. That means disabling the erase option was not accepted/ has been removed. Leaving me still with the problem of an EEPROM which gets erased.

Hello Jan

I have replicated your problem. Hm.

One work around for now would be to rn PPP directly from the following location.

"C:\Program Files\Matrix Multimedia\Flowcode V4\Tools\PPP"

In here you can load the hex file produced by Flowcode and also modify the options so they remain static. I will look into why the options through Flowcode are changing back to their default settings.

It could be due to the "-cs" option. Because our PPP app is used by a number of different products, we had to invent a system where different "config slots" were available so that PPP could have a different set of options and configurations when used by different products.

When you launch PPP to set the options, you must launch it with the same "-cs" parameter as when you launch it to actually reprogram the device.

If you only ever intend to use PPP with Flowcode, then you can remove the "-cs X" parameter from both the "programmer" and the "programmer configuration" parameters.
