Problem with MRCC FW update

[BruenMusic]

Hi there,

I tried updating my MRCC from FW version v 1.1.052 to v 1.1.075, but have issues.
I opened the hex file in the Teensy loader. Click on the Auto button (lights up bright green, like in the instructions). The Blue light is lit on the MRCC and then I push the recessed FW button on the MRCC. The blue light will go off and ... nothing happens. The unit is on, but can't excess anything. When powercycling it does boot. For clarity: No I did not use the FW of the NDLR.

I used the Teensy loader both on Windows 10 and on Mac OS (Sierra).
What am I missing? Or am I missing a step? 

Here's what the LOG-file says:

The biggest issue that I see with this is that the user will occasionally connect to the computer with the USB C "Power" port, rather than the USB B "PC" port. Can you confirm for me that you're connected to the computer with the PC port for me?

Hi Jesse,
Thanks for clarifying this. I was connected with the USB C "Power" port, because I did my other FW updates that way too (I think).
Will try with the computer PC port and let you know.

Hi Jesse, used the PC port and worked. Problem solved. Thanks!
Love my MRCC!
