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 3.3V
J2 connected to a different 3.3V source
J3 jumper was removed
SWC1 DIP switch was all in on position
J4 jumper was in 'enable' position
I really appreciate your help.

Should some signalling be done on the SCS pin during chip startup to enable the UART interface. Could this be related to the problem am facing ?
Thanks in advance for the comments.
