Not able connect to FRDM_K20D50 eval board on OpenSDA

admin — Thu, 23 Jan 2014 06:01:16 GMT

Hi,

I am trying to connect the FRDM_K20D50M evaluation board and debug a simple application of "Hello World". I have written a simple program of Hello World and trying to do a step debug.

The PC is connected to the SDA USB port on evaluation board. The programmed code (came with eval boards) is working fine after it gets power from SDA USB port.

When I try to connect the board from debugger, it gives error not able to detect the target hardware. (The board is physically connected PC over USB). The drivers are getting installed properly (checked from device manager)

Can anybody suggests what could be the issue in detecting the FRDM evaluation board using OpenSDA. Is there any standard document available which details out the procedure to debug using OpenSDA?

Thanks in Advance.

Thanks & Regards

Hello,

could you provide details on the error message you get?

But I believe you have not loaded the 'debug application':

Here are a list of articles which should help:

- Overview of OpenSDA: OpenSDA on the Freedom KL25Z Board | MCU on Eclipse

- Typical error situation: The Freescale OpenSDA Trap: “No Device Available”, or something like that…. | MCU on Eclipse

- New P&E firmware which has combined Debug+MSD: http://mcuoneclipse.com/2013/12/14/new-pe-opensda-firmware-v114/

I hope this helps.

Your 'settings.png' shows your problem: the connection type shall not be GDI Generic. It needs to be P&E.

Hello,

I am able to connect the FDRM board with OpenSDA. Actually the file *.SDA required for the openSDA to run was missing. I get the board in Bootloader mode, copied the required file and then after power cycle of board, I was able to connect the board.

Thanks & Regards
