I am working with TWR-K65F180M and using sdk 2.1. I want to use the board (using 8GB card on board) as a mass storage device, so that when I connect the board to PC using a micro USB cable the board should enumerate as a mass storage device.
I am working on usb_device_cdc_vcom example code given in the sdk 2.1. I connect the target board to PC and run the example code with default jumper settings. Now I open up the jumper J23 (open all four pins), connect 6-7 pins of J9 and connect 3.3V external power supply between J9 pin 2 and TP12.
The user guide says I should see echo on tera term and a device(Virtual com demo) on device manager but none of the two is working for me. I only see "USB device CDC virtual com demo" on tera term.
Kindly help me identify if there is any thing wrong with my settings or processor.
