I am facing an issue (CPU resetting) with MK64FN1M0VMD12 freescale freedom bootloader (FSL 1.0.2) and WinUpdater communicating over Serial port.
K64's boot loader boots up fine and when I ping it from Winupdater it gets into "bootloader_run" which is expected but then after a little while CPU resets.
When I say ping from Winupdater what it means is (I have disabled erasing and writing flash functions from Winupdater code) after I press "Update" button on Winupdater GUI (This is for debugging only) it just sends a serial ping message.
I have verified K64 receives the serial ping message and gets into "bootlader_run" function (verified with IAR IDE) but after that it takes <= 5-6 seconds and the CPU resets.
Any ideas ?
HW: I-JET Probe (JTAG)
SW: IAR IDE v7.20, FSL 1.0.2 (Freescale Boot loader for MK64FN1M0VMD12), Winupdater (FSL 1.0.2)
