kathirkamuannak — Wed, 07 Sep 2016 04:48:33 GMT

Dear Sir,

I am using Kinetis mk20dx128 controller for my project. I need to collect the faults occured in my project(which saved in my the FLASH memory) and store it into the micro SD card through USB. I am new to this USB and micro SD. Please point me in the right direction to some tutorials, pdf and sources which help me to complete my project.

Thanks & Regards,

A.Kathirkamu.

You can get all required USB and SD card resources for the K20 from
- http://www.utasker.com/kinetis/FRDM-K20D50M.html
- http://www.utasker.com/kinetis/TWR-K20D50M.html
- http://www.utasker.com/kinetis/TWR-K20D72M.html
- http://www.utasker.com/kinetis/TEENSY_3.1.html
- http://www.utasker.com/kinetis/tinyK20.html
including detailed documents at http://www.utasker.com/docs/documentation.html

Possibly a practical solution for your work is to use a virtual mass-storage device as described in http://www.utasker.com/docs/uTasker/uTaskerEmulatedFAT.pdf so that your faults are directly visible via USB as a formatted file.

Dear Sir,

Is there is any simple example project created with Processor Expert beans?

Thanks & Regards.

The tools have little support for older processors like the K20 so you might be best changing to a K22 if you need to use such methods. Although I haven't checked, so you could first do some tests to see if you do find something.

I'm using the K20DX128 with the tinyK20 (which is supported as well by uTasker: http://www.utasker.com/kinetis/tinyK20.html).

I have several Processor Expert projects for KDS published on GitHub (mcuoneclipse/Examples/KDS/tinyK20 at master · ErichStyger/mcuoneclipse · GitHub ). They use Processor Expert with extra components (see https://mcuoneclipse.com/2014/10/21/mcuoneclipse-releases-on-sourceforge/).

Some links:

I hope this helps,
