for serial loading using KBOOT, SREC, IHEX, AN2295 developer's loader and/or USB-MSD (device and/or host), SD card (or even Ethernet using external ENC424J600)....

Hi junwang,

    If you want to use uart to download the code to the KL26, you need to use the UART flash bootloader program, then relocate your application code.

    For details, please refer to our kl25 kinetis bootloader 2.0, which can be downloaded from this link:

Kinetis Bootloader|NXP 

    You can find the kl25 uart bootloader from this folder:NXP_Kinetis_Bootloader_2_0_0\targets\MKL25Z4

    More details, please refer to document in :NXP_Kinetis_Bootloader_2_0_0\doc

    Besides, we still have the application note about the uart bootloader:

Wish it helps you!

If you still have question, please let me know!

Have a great day,

Jingjing
