TMS320F28379D: usb_host_msc example in C2000Ware serial communication issues

Hi Eric,

Can you try with the "View-> Terminal" option within CCS? You can open a serial communication here with 115200 as the baud rate and try the same functionality.

Let me know which version of C2000Ware that are you using? The "usb_host_msc" example uses the "ReadLine" function in "usb_ex7_host_msc.c" file for processing the serial commands. Please try adding a breakpoint in this function to check if it is receiving the commands

Best Regards

Hi Siddharth,

Thanks for the response.

I am using C2000Ware_1_00_06_00.  Would upgrading to latest version resolve the issue?

I am away from the office for a few days, but when I return I will try your suggestion about "View-> Terminal" option within CCS.  I had already tried setting a breakpoint in ReadLine function and it was not receiving any characters from PuTTY terminal.  I'll try breakpoint when using CCS View-> Terminal.

Thanks.

Eric

Eric,

Recommend to try with the latest version of C2000Ware (3.01.00.00).

Let me know your observations once you are back in office.

Best Regards

I updated C2000Ware to version 3.01.00.00.  I also update C2000 compiler (via the CCS 'Check for Updates') to version 18.1.8.LTS.  I then tried to import the example Driverlib 'usb_ex7_host_msc' found in 'C:\ti\c2000\C2000Ware_3_01_00_00\driverlib\f2837xd\examples', but I am not able to import it.  The message (shown below) indicates "Compiler version '18.12.1.LTS' is not currently installed.  But I have the most up to date compiler version installed (18.1.8.LTS) according to CCS 'Check for Updates'.  I don't understand the reference to compiler version 18.12.1 vs. 18.1.8.  Please advise.

Eric

Eric,

Request you to download the compiler from  version 18.12.5.LTS.  You can install it in your <CCSInstallDir>/tools/compiler folder.

Best Regards

Ok.  Now I have C2000Ware_3_01_00_00 installed and compiler v20.2.1.LTS installed.  I set a breakpoint in the function ReadLine in the file usb_ex7_host_msc.c on the line of code containing SC_readCharBlockingNonFIFO.  The breakpoint is never reached when I enter characters at the Terminal.  I tried CCS Terminal and PuTTY Terminal; serial port COM4, 115200, No Parity, 1 Stop Bit.  Note that the Terminal program does receive characters from the usb_ex7_host_msc.  For more details, see the pdf file I attached to my original post.  It seems that the ControlCard's FTDI serial port is not relaying the characters to the TMS320F28379D device.  Any suggestions?

 
// Loop while there are characters that have been received from the SCI.
//
while(SCI_isDataAvailableNonFIFO(SCIA_BASE))
{
    //
    // Read the next character from the SCI.
    //
    ui8Char = SCI_readCharBlockingNonFIFO(SCIA_BASE);

Thanks for your help.
