Thanks Jilisegiar for your help.

I thought the USB demo code of Virtual COMM Port from STR7/STR9 USB developer kit software was developed based on the IAR STR912 EVAL board. However, it is not. See the Hardware configuration below. GPIO P0.1 is the USB connection signal, but P7.0 in the IAR STR912 EVAL board.

I am using Keil UVersion3 and MTB STR9 EVAL board and would like to move the demo source code of Virtual COMM Port to the uVersion 3.

The issue is that the demo USB code configures UART0_CTS P2.0 and UART0_RTS P3.3. The MTB STR9 board does not support the UART0_CTS and UART0_RTS. What I can do can fix this issue.

I really appciate any help from you.

I am reading the source code of USB development software that is developed based on the IAR STR912 evaluation board. Can someone provide the schematic of the eval board to me so that I can understand the source code more easily.

Thank you very much for your help.

attached you find the IAR STR912-SK board schematic
