I am working as firmware Developer. We are working on Cortex M4 Series micro controller (MK22Fx512).
Is there any method to upgrade firmware over the Air? Our device have GPRS Connectivity.
Thanks in advance.
Hi Mayur Savaj,
the below is the link for AN2295 which is on developing a serial bootloader.
you can also download the corresponding SW for AN2295 by searching AN2295SW in Freescale website.
Here suppose your GPRS module is connected to MK22 by using a serial port.
if you can reset the MCU, then, by transfer data via GPRS, you may update the firmware.
I hope it helps!
