Hi

I have developed my code (assembler) using the InDart ST7F Run the code with no problems.

I am now using the DataBlaze programmer to programme the ST72324J which programmes fine. i.e all the code runs.

But if I Programme & verify or verify at a later time, only some of the code runs, i.e. some of my subroutines do not seem to function.

If I programme and never verify all is well and all of my code runs.

I am not using the hi memory locations that the InDart uses FF28 to FFDC but is there some other memory that is used only when the ST7F verifies.

Any clues

Hi Brian,

I've had problems with programming and verification of X-flash when the micro is run at fairly low voltatges. Can you guarantee the supply is OK (within specified limits) during programming?

Cheers,

Gary

Voltages ok

I have now tried using the InDart STX and this verify's ok without affecting my code?
