Virtual serial port

juliancox — Tue, 24 Apr 2018 08:10:26 GMT

I have never used this facility before, so a LOT of help would be useful. I am using a S08QE with a MUltilink FX (I also have a DEMOQE128 if necessary).

I am developing a control application and I need to download data acquisition (probably ~4K) from the target for analysis on my computer.

How can I use the Virtual Comm utility do do this? Do I need code in my application in order to communicate serially, or does the BDM interface take care of it? The P&E documentation is a bit light on detail.

I have a 64-bit Windows 7 and so the P&E utilities will not install.

Hello Julian,

- The "Virtual serial " is intergrated in OSBDM/OSJTAG debug of NXP( Freescale) tower board,

that is to say if you use the demo board of freescale, there is a Virtual serial in tower board, so the microcontroller can output data to PC.

While the external debugger MUltilink FX only has debug function, if you want to send data ,

you can use the Serial Communications Interface .

About the detail , please have a look at "OSBDM_OSJTAG_Virtual_Serial_Toolkit_Resources.pdf" .

- If you use CodeWarrior IDE, you can create a proejct based Processor Expert ,then add the "AsynchroSerial" component ,there is demo code 。

Hope it helps

Alice

Thank you for your help. However, I cannot install the Virtual Serial Toolkit as it is not compatible with 64- bit Windows, (or is there a 64-bit version?)

Hello Julian,

It seems your tool version is not the same with mine:

I don't know why, but I downloaded it three times an on the third time I got the same version as you and now it works fine. Thanks.
