Read firmware from SD-card, copy it to flash and execute it

[becktho]

Hi there.

Is there anyone around who has experience in writing a bootloader for the Kinetis MCU, which reads a firmware from an SD card, copies it to the program flash and then executes it?

I am looking to do this as well on the k10 if someone can point me in the right direction to get started.

I currently get closer to a solution.

I used the mfs/sdcard and mqx/flashx examples as a base to build my own code. Using these example shipped with MQX it gets much easier (if you can use MQX in the end).

Were you able to get this to work successfully?

I too am working on a bootloader that loads from SDCard.  I am interested to see how you did yours.

Thanks

Hi becktho,

could you post the link where I can find this example?

thanks.

Hi Alex

If you did not find them yet - these examples are shipped with the MQX package. If you extract the zip file you should have example sub folders, containing different examples you can test.
