Cannot update the bootloader for KL28Z


Just bought my KL28Z board. I only succeeded to update the Daplink to version: 0242 Unfortunately i am not capable to update the bootloader.

I am doing this update from my iMac running High Sierra OS X.

Iused the following file: OpenSDA-2.2-Bootloader-K20DX.bin I get the following error: Assert File: ..\..\..\source\daplink\drag-n-drop\flash_decoder.c Line: 157 Source: Bootloader

I would appreciate if you could help. I am new to these kind of boards.

Thank you,

Hi Gheorghe

The file you are using, OpenSDA-2.2-Bootloader-K20DX.bin, is a raw bootloader binary and cannot be programmed with drag-n-drop. To update your bootloader you'll need to use a special bootloader update image. This update image and the steps to update can be found on the blog post here: https://os.mbed.com/blog/entry/DAPLink-bootloader-update/
