Hello,
I am using the FRDM KL25Z on my macbook pro.
I also use VirtualBox to use windows, and code warrior.
All works fine, but some times juste when i connect the USB cable, my computer freeze during 3 secondes, and shut down, then restart.
Doest some other people had this strange issue ?
Or do you have an idea of the reason ?
REGARDS
Hi
We don't have record about similar issue.
What kind of USB function of FRDM-KL25Z board?
Could you change using another USB port of Macbook pro? If both USB ports could cause the same phenomenon?
Wish it helps.
Have a great day,
Ma Hui

Hi
Sorry for the so later reply.
I would recommend customer update the OpenSDA firmware with Segger provided J-Link firmware.
I checked there with description that :
Due to limitations of the OpenSDA bootloader replacing the firmware to use it as a J-Link can only be done on Windows and Linux systems. When the firmware is replaced, it can be used like any J-Link on Mac OS/X, too.
More detailed info, please check below link:
SEGGER - The Embedded Experts - OpenSDA / OpenSDA V2
Wish it helps.
Have a great day,

Hi
Do you have the IDE software?
You could using J-Link to debug the code, which will program the KL25 Flash before debugging.
Wish it helps.
