C2000-GANG: C2000-GANG Performance problem

Hi yingjiao LI,

We are reviewing this with GANG - will get back to you in a day.

Thanks and regards,

Hi,

I can se that on some slots the target can be programmed, and for other - not. Can you email me picture of your bench? I would like to see wiring between C2000-GANG and your targets.

Hi

Please find the wiring picture, and attach our burning schematic

Hi yingjiao LI,

What is the power source for the target board? If it is from the programmer, then I expect that the programmer is overloaded. The max current provided from the programmer is 150mA. I assume that the whole board is consuming more. Can you try an external power supply and see if that helps?

On the scope, you can also check Vcc from the programmer during programming and see whether it is always stable at 3.3V or not.

Thanks and regards,
Vamsi

Our power supply is provided through the adapter provided with the burner. When the burning fails, the voltage measured on the DSP side is 3.1V. We have a 5V to 3.3V power chip on the adapter board for external power supply. Later, I removed this adapter board and now all 8 ports can be burned successfully. However, when two channels are burning at the same time, we encounter the following problem: not every time the burning is successful, there are always cases of burning failure, The following is my connection and the prompt for burning failure. Please help check the reason

Hi yingjiao LI,

Thank you for the update.

We will review and get back to you this week.
