Hello,

I am porting my system from MQX 4.0 to MQX 4.2  but I can't find example code of "Bootloader" in version 4.2.

I read the release note of MQX 4.2. It shows that Bootloader is avalable , but there is no example code.(there are only

bootloader_vybrid and bootloader_vybrid_qspixip.No bootloader!!)

I installed MQX4.1 before and I can see all the three item, but my system need MQX4.2 to support K64.

Or it's just no example, MQX 4.2. still support the old Bootloader of 4.0 & 4.1.

Thanks in advance.

Justin

Hi Justin:    

       

Unfortunately there isn't an example like what you need. The bootloader in MQX 4.1 is for Coldfire not for Kinetis devices.

However NXP/Freescale provides some application notes about Kinetis K product bootloader.  You can use this for reference.

The app note might help, but the link you provide returns "Not Found".

Link for AN4367 no longer links to anything.

Search for AN4367 is also a dead end.

Is there any support for a K60 ethernet based boot loader?
