Bootloader Mode Error

Saiwenliang — Wed, 23 Sep 2020 02:10:33 GMT

Hello, I encountered a problem when using the development board frdm-ke06z: after entering bootloader mode, I loaded the flash program app according to the following prompts according to section 2.1 and 2.2 of 《OpenSDA User's Guide》 but it has not been successful.

The indicator light of the development board will prompt an error state (2 seconds off followed by 8 rapid on/off blinks) after each power on. How to solve the problem or what steps should be paid attention to?

Hi,

It seems your opensda has been corrupted.Refer the attachment PDF . Use a external jlink to update the bootloader and firmware.

Have a great day,
TIC
