I'm trying to bootload a KL43Z board through SPI. I was able to start the bootloader by connecting the BOOTCFG pin to the ground, and resetting the board.
I checked it with the debugger, and I'm sure that it booted from the ROM. I read the KL43 Sub-Family Reference Manual, and it's not clear for me that in bootload mode, which peripherals are acive at which pins.
I assume that somewhere there is a pin mux table that shows that which peripheral is connected to which pins after bootloader initialization.
Can somebody help me in this matter?
