Hello Sreerama Dhanalakshmi

Fan_Yang is right. Check your UART communication first if you are using your custom hardware.

Connect your hardware to PC (you can use putty or access port etc) and send 0x5A 0xA6 and check is there any output given by hardware while running bootloader?

Bootloader code will acknowledge  0x5A 0xA6 command.   

Let me know if any..

Regards,

Harsh

Hi

Which board are you using? FRDM-KL25/TWR-KL25 or customized development board?

If you are using the NXP designed board, there should be no such issue.

If you are using a customized board, please ensure that the default PINMUX in the bootloader code matches your board design.
