Hi there,


I am programming the MCF51QM128 device with my programmer, but some of the devices are not programmed corectly.


The problem is that after loading the bootloader to RAM and starting BDM GO command, the MCU is reset. The reset pin is tied low after around 5-6us. The reset stay in low position for about 86us. Can you please advice how to check what is causing this reset?


I have some devices that are working ok with the bootloader and are programmed and thwere are few MCU which does not.
