IWR6843AOP: Uniflash 8.5 not finding device on Mac OSX

Part Number: IWR6843AOP
Other Parts Discussed in Thread: UNIFLASH,

Hello! I am at my wits end with flashing a mmWave device.

I am using the Silicon Labs cp210x (latest) for OSX and a TI IWR6843AOP. I cannot for the life of me get uniflash and the TI device to talk over these virtual com ports. Does anyone have a voodoo ritual for getting this to work? The TI forum experts were not helpful as it seemed they were incapable of reading all the way to the end of a paragraph.

 

  1. The device talks fine to TI's online demo software, so I know the device is capable of communicating.

  2. I bought a brand new usb-c to micro-usb DATA cable for this device. No luck.

  3. I do not own, nor have access to a windows PC.

  4. Tried online and locally installed uniflash, neither work. It fails when trying to open the com port.

  5. My virtual com ports ('enhanced' and standard) show up as /dev/tty.SLAB_USBtoUART and /dev/tty.SLAB_USBtoUART3

  6. Screenshot of error in the link. Same error regardless of which port I use.
