Hi

I'm having trouble with most of the software versions of JFLASH , because after I program a Uc it programmed right the first time

but to program the next one, it always appears an error. So I have to select the option "program" twice to program the Uc.

The Software should not show this error each time that I try to program a new UC, right?

The MCU that im using is the STM8S207K6, and this issue it's only happening when I try to program different chips and not when I try to reconnect the same chip.

The error appears as a screen shot as a log window error as apear below.

Log Window:

Failed to program target


So as its has shown in the log window, that it appears an error between each successful programed chip .

Any other datail or information you need please let me know.

Hi, Oliver

Answering your cuestions:

Q:Is your target powered externally or powered via Flasher ?
A: The target it's powered by a 5V DC external source .

Q: Are you dealing with Read Out Protection (byte @0x4800) when programming ?
A: I'm not reading, I'm just programming Target. Either way the chips are blank so they aren't protected.

Q: Has the target been disconnected or changed during the several programming attempts ?
A: I have several STMS207K6 targets, that I have to program with the same code, that way i use the same setup or configuration the only thing that change is the target for another STMS207K6. Each time I Program successfully a target, I connect the next one with the same setup but fail the firs time I try to Program the target, the second time I try to program it using just the same setup as the first attempt but this time it happend a successful operation. So when the target is programmed successfully i changed for another target and happend the same way.

Q: Do you try to program the same device twice ?
A: Always have to select the option "Program" twice because on the first attemp it always fail to program the target. So Always have to program the same device twice to have a successful operation.

URoman

Hi Oliver,

The problem was solved by interrupting the external power source each time I connect a different chip.

Thanks for your support.
