I was also following that DOC-103288 and originally had the same error:
| Resource | Path | Location | Type |
| fatal error: device/MK64F12/MK64F12_adc.h: No such file or directory | fsl_device_registers.h | /FRDM-K64_HelloWorld_GPIO_ISR/Includes/device | line 430 | C/C++ Problem |
It went away when I compiled the SDK *before* creating the new kds project with the wizard. The first time I went through the tutorial I forgot that I had upgraded to KSDK_1.1.0 and first compiled it when reminded to do so after step 3.15. In the picture below, the project "FRDM-K64-HelloWorld_GPIO_ISR" is from the first attempt when I had the error in fsl_device_registers.h. When a new project "test" was created after compiling the SDK and using the exact same procedure for the New > Kinetis Design Studio Project wizard, a new folder SDK was included where fsl_device_registers.h eventually lives.
The "test" project compiles perfectly, but I am now wondering why the SDK folder doesn't appear in the structure from the tutorial? The first project I created, with the compilation error, *does* match this expected structure. This SDK folder also isn't included in the demos, as shown in the "hello_world_frdm64f" project.
