Part Number: MSP430F5659
Other Parts Discussed in Thread: MSP-FET

Tool/software: Code Composer Studio

Hi Sirs,

I'm trying to do CDC-class USB communication using MSP4305659.

I built the example C3_EchoToHost and loaded it into a MCU to connect to the PC, but the usbser.inf driver is not loaded on the PC side and communication cannot be established.

Could you provide an example project for MSP4305659 that is working properly if possible?

Or give me some advice.

target :our designed board

debugger:MSP-FET Serial 19010105D

CCS:Version: 10.1.1.00004

Compiler:TIv20.2.1.LTS

Example:MSP430USBDevelopersPackage_5_20_06_02\MSP430_USB_Software\MSP430_USB_API\examples\CDC_virtualCOMport\C3_EchoToHost

Thank you,

    What is the XT2 value? And source code if configured for this value? Try to upload firmware without MSP-FET, by HID BSL using BSL Scripter (CLI) or USB Firmware Upgrade (Win GUI). Just mass erase target by FET, and device should be enter to BSL mode automatically, after reset or power-up.

    If BSL is working OK, than everything regarding USB hardware part is OK.

    Win 10, Linux and OS X does not need any OS / driver for CDC device. It should be enumerated automatically by OS just fine, without asking for any file / driver. INF file for CDC device is only used for older Win versions.
