iMXRT1020EVK Hello World virtual com example

Hi,

 

Greetings!

 

Running the evkmimxrt1020_hello_world_virtual_com example.

When I am using semi hosting, I can see the "hello world" output in mcuxpresso 's console.

Attached screen capture.

 

I was expecting to see the output in a Terminal emulator, such as Putty or Tera Term;

Tried switchng to the Terminal be setting

Quick Settings -> SDK Debug Console-> UART Console

But, I still do not see anything on Putty/Tera Term.

 

Any idea, what could be wrong ?

 

Thanks,

Manu

Replying to my own post ..

 

I did some experimenting.

The reason why there is no terminal output was there was no vcp driver.

Device Manager looked thus (no_vcp.png):

 

I tried to force load mbed vcp driver. The load process said, it would not work with the hardware..

Still thought, I should give it a go...

Loaded the mbed vcp driver (mbed_vcp.png).

Connected Putty over COM10

 

And it worked!

Lucky me, I guess...

I tried this demo on my side, with my Win10. It worked as expected.

 

There is a readme file for this demo

SDK_2.8.2_EVK-MIMXRT1020\boards\evkmimxrt1020\demo_apps\hello_world_virtual_com

Hi Daniel,

 

Win7 at my side. Maybe that explains. There were some other issues. Windows 7 does not have the USB Audio Class 2.0 drivers as well, regarding the USB Audio examples.

 

Thanks,

Manu
