I have A TWR-K60N512 KIT with the TWR-K60N512, two elevator boards, and the TWR-SER board. Using KSDK 1.3, I am simply trying to build, load, and run the hello_world demo using IAR Embedded Workbench 7.40.3. I am using a J-Link pod from Segger as my JTAG connection.
The ksdk_platform_lib project builds fine, no errors. The hello_world project also builds fine, no errors. I can download the project into Flash without errors.
However, when the code gets into CLOCK_HAL_PrepareOsc(), it fails with a HardFault. This function is in fsl_mcg_hal.c. The failure appears to be happening at the line:
In the disassembly window, I can see the following code:
0x1176: 0xf114 0x000c ADDS.W R0, R4, #12 ; 0xc
0x117a: 0x0140 LSLS R0, R0, #5

0x119a: 0xf7ff 0xffc8 BL CLOCK_HAL_IsOsc0Stable ; 0x112e
0x119e: 0x2800 CMP R0, #0
Whenever I try to execute the code at 0x118c, the code immediately goes to HardFault_Handler at location 0xe66.
Any idea what could be causing this? Not sure if I have something configured incorrectly in board.h, or if I have incorrect jumper settings on either the processor board or the serial board.
Any help is greatly appreciated!
