FRDM-KL27Z Schematics and Bootloader Questions

I'm doing a fairly simple design using the MKL17Z256VFM4.

There's a couple of things I'd like to ask you.


I ordered the FRDM-KL27Z as a dev platform.

Is this the best dev platform for the KL17?

Are the schematics available? I didn't find them.


About the ROM Bootloader:

Apparently you can force the CPU to enter the bootloader by asserting the BOOTCFG0 pin which is apparently the NMI_b pin; what does assert mean in this case? Is it high or low?

  The Bootloader looks at LPUART among others as a boot device. Which one does it use? LPUART0 or LPUART1 or both?


Thanks for your help,
