TMS320F28388D: Project usb_ex1_device_serial_cm.c not working

Peter Wi

Part Number: TMS320F28388D

Hi,

the USB Serial Device example for CM usb_ex1_device_serial_cm is not working, no USB serial Port is shown on my Windows PC

The example for CPU1 usb_ex1_dev_serial.c is working, i can see the TivaWare USB serial port as Device on my Windows PC.

Any ideas ?

Hi Peter,

Can you elaborate on the steps that you did when you tried to run the example on CM side.

Best Regards

Siddharth

Hi Siddharth,

i commeted out the stuff i don't want tu used in the application for cpu1.

i init the gpios for use as usb and assign them to CM.

CPU1 stays in an endless loop with an LED1 flashing.

CM starts up initalize all the stuff for hardware, setup systick, setup

USB like the example for cm and CM stays also in an endless loop,flashing

LED2 and serving usb.
