Hi,

Please provide detailed information like below, so that we can try to find out the root cause together and figure out the solution.

1. Kinetis Bootloader version

2. Peripheral

3. Speed

Thanks

Fan

Hi,

Regarding the Peripheral, I mean UART/SPI/I2C/USB HID, please let us know which peripheral you are talking to now:)

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.

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..
