gpt说需要用示波器看看DTR和RTS波形是否真的被拉高拉低了,但是我现在搞不到示波器 ^-^

我第一次开发H7系列的,板子上只画了电源指示灯;gpt的意思是他觉得CH340X部分电路没问题,建议我去用示波器看波形,但是我现在搞不到示波器 ^-^

另外拿块板子做示波器不就行了 ^-^

STM32H723: Can't connect to bootloader via UART / at all | Community
I am trying to use the built-in bootloader to flash a new firmware onto my MCU (STM32H723). Unfortunately, I cannot get any reaction from the MCU when trying to connect to it, and I am struggling to diagnose which step is going wrong.Short version of...
- BOOT0 high & NRST low
- Wait 1s
- NRST high
- Wait 1s
- BOOT0 low
- Connect using Baud rate 115200 (9600 works as well), even parity, 8 data bits, 1 stop bit, flow control off

你用kell,配置一下芯片的型号,看能不能烧录。
