Kinetis Bootloader TWR-K21F120M

I am looking for a version of the Kinetis Bootloader for the TWR-K21F120M kit.

I tried porting the IAR project by tried following the recipe from here:

Kinetis Bootloader for MK22FN1M0XXX12  

I have finally been able to compile without any errors, but when trying to debug the tower_bootloader project and initializing the device, I get stuck in the clock_mode_switch() function waiting for external reference clock to be ready. Most likely, this is not my only mistake, so if there was a finished project or source code for bootloading TWR-K21F120M somewhere, that would help me a lot.

Hi Marte Skjønsfjell,

I had already ported the MK64F12 to the MK21F12 and the ported demo ran well on the TWR-K21F120M board.

The attachment is consist of the head file and project and assure them are settled in the ~\NXP_Kinetis_Bootloader_2_0_0\NXP_Kinetis_Bootloader_2_0_0\targets and ~\NXP_Kinetis_Bootloader_2_0_0\NXP_Kinetis_Bootloader_2_0_0\src\platform\devices respectively, then open the project later.
