When I used the ADUCM361(R7) MCU, we could not download through the three pins of RST, SWD and SCLK. J-Link/ST-Link was able to identify the chip, but the download failed.
I also measured the overvoltage and the voltage looked normal. I tried to slow down the download speed, but it was also download recognition.
The Keil version is V5.38.0.0 and the J-Link version is V7.96b.
Is there any other reason? I am currently not troubled.
