Connecting over Vcom

[Samuel S]

Hello Mark,

Feeling dumb as always.  I'm trying to follow your example below:
https://community.nxp.com/t5/i-MX-RT-Crossover-MCUs/iMXRT1062-Ethernet-over-USB/m-p/1440177

I can flash the code to the board without issue and it enumerates as a Vcom and RNDIS device.  Screenshot attached.

But I can't connect to the Debugger as described.  Attached a screenshot from Putty.

I tried with Terraterm but the same results.

I then try to follow the advice in:
https://www.utasker.com/docs/uTasker/uTaskerSerialLoader.pdf

But after loading "uTaskerSerialLoaderUpload_MIMXRT1060.bin" I see no Com's to connect to.

What am I missing?

Regards,
Sam

Hi

I would try first without RNDIS in case that is causing a problem with its composite configuration.
Also compare the operation withe a reference from https://www.utasker.com/iMX/RT1060.html since these are known to operate correctly.
