TLV320ADC3101 and Pure Path

Other Parts Discussed in Thread: TLV320ADC3101

Hello,

I use the TLV320ADC3101 EVM together with the USB-MODEVM. When I try to download miniDSP code via Pure Path Portable GDE, the error "Hardware Device Not Connected" is shown. I am able to connect to the board with ADC3101 CS Config Tool. Why can't Pure Path connect to the board??

Thanks and have a nice day

    Hi, Marc,

    I have asked my colleague to look at this with you.

    You need to update the firmware on the EVM.

    Please use the attached firmware files.

    * flip the SW2-A2 switch on the USB modevm to the right (HI).
    * connect the EVM to the PC and follow the instructions to install the TI DFU driver (in the attached zip)
    * once the driver has installed, flip SW2-A2 to the left (LO).
    * launch DFUTest.exe
    * click Program EVM, choose file DFUEE.bin (in the attached zip) and follow the on-screen instructions
    * choose USB-miniEVM0204_441kHz.bin (or a .bin file with the desired sampling rate) and follow the on-screen instructions

    * disconnect the EVM and re-connect the EVM.

    It should now work with PPS.

    Hello,

    thanks for your answer. I can connect to the evaboard now and debug the miniDSP application. I have one additional question. As already mentioned I use the TLV320ADC3101 EVM and the corresponding framework component as you can see in the screenshot above. I am not able to change coefficients during runtime. In the properties window of the framework component adaptive mode is disabled and it is read only?!

    What do I have to do in order to be able to change the volume coefficient during runtime?

    Thanks

    Marc
