Other Parts Discussed in Thread: OMAPL138
Hello
I am working on LCDKOMAPl138 and I need to check USB Serial device interface.for that I am using Starterware code and using CCS studio I imported
Usb_dev_ser code from /home/OMAPL138_StarterWare_1_10_04_01/build/armv5/cgt_ccs/omapl138/lcdkOMAPL138/usb_dev_serial.
Build the project and Debug
My connection on the board is
1.one cable is connected as serial terminal(Connected to USB-Uart port to PC)
2.2nd is connected between USB-OTG port(As a Serial Device) & Host PC
when I run the code and after successfull run I am giving command "dmesg" in linux terminal then following log will appear
$ dmesg
==============================================================================================
[156786.599008] usb 1-3: New USB device found, idVendor=1cbe, idProduct=0002, bcdDevice= 1.00
[156786.599009] usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[156786.599010] usb 1-3: Product: Virtual COM Port
[156786.599011] usb 1-3: Manufacturer: Texas Instruments
[156786.599011] usb 1-3: SerialNumber: 12345678
[156786.603866] cdc_acm 1-3:1.0: ttyACM0: USB ACM device
=======================================================================
so it means serial device is detected.
After this I am trying to run a simple program which will transfer data to /dev/ttyACM0 but no changes seen nor data is recieved on /dev/ttyACM0 terminal
and my primary requirement is I want to use Baremetal(Starterware) code only. I have tried using SDK Rtos Pdk but i cant use this code.
please guide me regarding this.
Thanks in advance
regards
