Firmware over the wire (USART, I2C, etc.)

Hi all.

I am currently working with a sensor system which is wired together in the bus. There are alot of focus on FOTA bootloaders, but i was wondering if there are any wired IAP applications?

I have been searching through the code library but was not able to find anything relevant.

Looking forward hearing from you all!

You don't mention which device you use, and your profile has also none. But here is an example: http://developer.mbed.org/users/Sissors/

I am sorry for the lack of information. I have no particular brand og model in my mind.

Is it very specific for a particular device?

That one is quite specific for Freescale devices, but you can do similar stuff on other once too. NXP devices also have an IAP library on mbed.

Freescale seems to have a good selection of devices. I think the M0+ could be interesting. How realistic would it be to retrieve the data via U(S)ART or I2C?

Whoops I now see that I miss-copied the link, Ed posted the correct link (to Bootloader_K64F, so it is made for the K64F, but should be relative easy to adapt to other Freescale devices). It already uses the UART, so that should be realistic enough to implement ;).

The following code works very well and could be adapted: http://developer.mbed.org/users/Sissors/code/Bootloader_K64F/

I have a notebook page under development which may help: http://developer.mbed.org/users/ebowles/notebook/freescale-bootloader-fota-firmware-over-the-air---/
