STPM3x评估软件读取缓冲区长度不足

Parsons.Rob
“我尝试将EVAL-STPM32板连接到STPM3x评估软件，但在尝试读取数据时遇到以下错误。
错误消息：'读取缓冲区长度不足。操作已超时。'
PC运行的是Windows 7
STPM3x评估软件v3.1.0.0
在'选项 - ＆gt;接口'菜单，使用以下值：UART / COM 5/9600（波特率）
该板通过USB到UART桥接器（Silicon Labs CP210x）连接到PC。
J2连接到USB-to-UART桥接器
 
J7连接到3.3VJ2的外部直流电源，连接到不同的3.3V电源
 
J3跳线被移除
SWC1 DIP开关全部处于开启位置
J4跳线位于“启用”位置我真的很感谢你的帮助。

‌I tried to connect the EVAL-STPM32 board to the STPM3x Evaluation Software but encountered the following error when trying to read data.
Error message: 'Read buffer length insufficient. The operation has timed out.'
PC was running Windows 7
STPM3x Evaluation Software v3.1.0.0
In the 'Options -> Interface' menu, the following values were used: UART / COM 5 / 9600 (baud rate)
The board was connected to the PC through a USB to UART Bridge (Silicon Labs CP210x).
J2 connected to the USB-to-UART bridge

J7 connected to an external DC supply of 3.3VJ2 connected to a different 3.3V source

J3 jumper was removed
SWC1 DIP switch was all in on position
J4 jumper was in 'enable' positionI really appreciate your help.
