Hello Alice,
Thank you for your suggestions. Because of the issues reported when using a FRDM-K22F in a Windows 10 environment, I abandoned the OpenSDA v2.1 bootloader. It K22f eventually was corrupted so I had to use a Segger J-Link to reprogram the bootloader anyway. I used the Segger J-Link OpenSDA - Board-Specific Firmware for the FRDM-K22F 01_OpenSDA_FRDM-K22F.bin dated 2016-07-12.
I was then able to build and run the Hello World demo program successfully on a Windows10 computer. Yaay!! I'm using:
- Kinetis Design Studio 3.2.0
- J-Link V6.00
- Segger J-Link EDU debug probe
Now I'm having a new problem that may be because I'm not familiar with all of the Freescale tools. Without changing anything, I created a new project and I get the following error message:
J-Link GDB Server failed:
Could not connect to J-Link. Please check if plugged into USB port or Ethernet switch.
For more details, see the JLinkGDBServerCL console.
Here's how I created and built the new project:
Project Name: New_Project__SDK_2.0_FRDM-K22f__Segger_J-Link_6.0
Select Kinetis SDK folder: C:\Freescale\SDK_2.0_FRDM-K22F
Boards > New FRDM-K22F project
Build
Debug Configurations: GDB SEGGER J-Link Debugging > New_Project__SDK_2.0_FRDM-K22f__Segger_J-Link_6.0_Debug_Segger
Is a new, unmodified project missing something required to connect to the Segger J-Link debug Probe?
Here's the content of console after the failure:
