【GD32F350】The simulation fails after a burst of smoke [Copy link]

 

I was so naughty that I had to measure the 5V GND. I accidentally touched the test lead and it was short-circuited. It was smoking and I quickly pulled it out. The total duration was about 2S. In fact, at this time, I was still exclaiming: "Young man, you are so skilled!" I unplugged the power at lightning speed. I sighed that my charm has not diminished in the past. But when I plugged in the power, I was stunned. The emulator couldn't find the device! ! ! ! ! ! ! The emulator burned out. The device should not be seen in the debug. Did the young man become an old man? ? Or is the GD board really not made well? . At least I have played with many development boards and often encountered short circuits. It seems that this one is not well protected. I can't determine what is broken for the time being. I have to find a schematic diagram to look at. The download contains library manuals. I don't seem to see the schematic diagram. Can anyone share a schematic diagram? ? ? ? ? ? If it doesn't work, I guess I can only use jlink. I don't know if STlink supports PS. The program is still running. The program is still running. It's good.

It is estimated that GG, buy an emulator and continue playing

Our Father in heaven: Hallowed be your name. Your kingdom come. Your will be done on earth as it is in heaven. Give us today our daily bread. Forgive us our debts, as we forgive our debtors. And lead us not into temptation, but deliver us from evil. For yours is the kingdom, the power, and the glory forever. Amen! stlink can support, jlink does not have this device.

There is a circuit diagram in the official data summary. Check the circuit diagram to see what is broken.

I also carefully read the previous paragraph of yours. . .

5V is directly supplied by USB through a diode, so it should be a problem with the diode.

XIEXIE Thank you, I found that I downloaded the schematic diagram but did not unzip it. It's embarrassing

Open it and power it on to test where the simulator is broken. You can quickly find the problem with an oscilloscope

Is it easy to repair? Do I need to apply for official support?

Analyze how the short circuit occurred, and then take a closer look at the appearance of the components. If it is just a power short circuit, it is not difficult to repair.

The most worrying thing is a short circuit, and this situation will definitely burn the chip. Find the corresponding chip and replace it, and then continue to play.

I changed the diode and it has been solved. Lemon brother
