I am having a KL25 board and i updated the MSD-DEBUG-FRDM-KL25Z_Pemicro_v118.SDA boot loader firmware. Now i alter KL25 Boot Loader example in which i want to accept the application code from serial.
My question is :-
1) How to update the KL25 Bootloader code to the device
2) can i directly connect switch across PTB8 and 3.3 VCC.
3) what is the timeout between power on button pressing to switch form Bootloader Mode or Application Mode after loading KL25 Bootloader example
4) How i want to send the file through serial.
