Hi,

 

which default LPUART is used for communicatioin with the ROM bootloader in K82F?

Table 8-1.PNG

I'm using FRDM-K82F but I could not establish communication when using blhost. I've wired PTC3 and PTC4 to R36 and R32 on the board like recommended in the K80 FAQ.

The MCU's flash on the board is in erased state therefore the ROM bootloader should start up automatically but it doesn't work.

Or am I missing something?
