IWR1642: TMDSEMU200-U with IWR1642

Part Number: IWR1642
Other Parts Discussed in Thread: TMDSEMU200-U, , UNIFLASH

Tool/software:

I have just ordered a TMDSEMU200-U programmer device from digikey.com to research and reprogram an existing, well-functioning circuit (image attached). I would like to ask:

  1. How to connect the TMDSEMU200-U programmer to the IWR1642 chip using only 6 JTAG signal lines (GND, TMS, TDO, TDI, TCK, 3V3) as noted on header J2, correct?

  2. After successfully connecting, I need guidance on how to unlock the chip and erase all data to return it to the factory state, similar to the IWR1642 chip I purchased from digikey, on both TI DSP C647 and Arm Cortex R4x chips.

  3. After erasing all data, I need instructions on how to load and debug a sample program from TI using Code Composer Studio 12.7.1.

  4. After successfully running the test, I need instructions on how to lock the chip again (similar to locking the chip for commercial product use).

    Hello, 

    1. Please check the JTAG Connectors page at: https://software-dl.ti.com/ccs/esd/documents/xdsdebugprobes/emu_jtag_connectors.html 
      You can use the TI-14 Pin connector and connect to each of the JTAG signals that you mentioned. 

    2. I'm not familiar with the design you have shared. This is a custom design that you have made, right? Does it use an external flash chip or is it booting from some other host processor? Assuming it has an external flash, if you have access to the UART signals this will probably be easier. You can connect to the device and erase the data in flash memory using Uniflash. 
      If you don't have access to uart and JTAG must be used, then you can check out this JTAG Flasher tool in the radar toolbox, which you should be able to use to do the same. 

    3. Please refer to the documentation in our Radar Toolbox for Using CCS Debug. 
    4. Similar to 2. Uniflash or the JTAG Flasher tool should be used to load the fw to flash memory. 

    Best Regards,

    Josh
