Other Parts Discussed in Thread: TUSB3410, MSP430F1612

Hi,

    Am trying to do my own msp430 launch pad, where could i get eeprom and MSP430F1612 binary files to program this., and how i want to do this., now i prepared the board without writing binary files, the 12 Mhz clock has been supplied to TUSB3410, if i connect the my own module to pc , it showing that "unknown device" in Device Manager at USB  port.  it have to display as "TUSB3410 device".................   what i need to do , to get like this.

Thanks,

Thiyagarajan.S

    The FET firmware running on the 1612, as well as the EEPROM firmware for the TUSB chip are factory-programmed and updated by the MSP430.DLL (if a previous version is present). However, the FET Downdater tool should be able to install an old version and then the update should be done next time CCS or IAR access your pad.

    If you see 'unknown device' you should istall the generic TUSB drivers for a plain vanilla virtual COM port.

    Nevertheless, building own hardware and stufing it with the original firmware is illegal, even if possible without complicated hacks. If you don't plan to sell it, I guess that nobody will sue you, but...

    Hi Jens,

          Oh, my god . This much difficult is this ha ?. ok. i dont want any firmware. but i would like to know how that tusb3410 is get detect in device manager. Could you give some explanation about tusb3410 ? , usually where we use this ?, what it does ?, how much clock it needs ?..etc..,

    Thanks,

    I am just curious - what's the idea, why you are doing this? Project for electronics class? I would understand if you plan to put your own firmware into MSP430F1612 of TI launchpad, but opposite makes no sense to me. For example I bought a bunch of launchpads so *every* of my weekend projects have in-circuit programmer built-in :)

    Just clock on the link the forum has put on the device name. Teh datasheet is there.

    Basically, teh TUSB3410 is an 8032 microconroller with USB controller. It can read its firmware form an external I2C EEPROM (which is what is done on the LaunchPad) or can get it through USB from the PC driver. The standard PC drivers usually provide a firmware that turns it into an USB->SER converter. The LaunchPad firmware, however, provides a little more funcitonality. Main purpose is still an USB->SER conversion to feed the debug requests of the PC software to the MSP430F1612. But tit also  provides a secondary bit-banging up to 9600Bd serial channel that is used to route serial data form the MSP on the LaunchPad to the PC. And the specific PC drivers split the two data streams so you can communicate with the MSP through a virtual COM port while the debugger is attached and active.
