Problem with flashing Freescale MKL16Z128VFM4

Hallo guys,

I’m new in this Forum.

I have a problem with flashing my Freescale, Openocd does not complete the inti-command.

Openocd failt by reading or writing in the memory for Private Peripheral Bus.

At each try it’s an other adress, but some adresses are read- oder writeable.

The error-message look like this error:

I hope someone here can help me :slight_smile:

EDIT: Sometimes the init finished without errors

Hallo,

I think I have the reason for the problem, but no solution …

I think the watchdog resets the MCU every second and so the init can not be completed.

And if the timing is good, the init finished.

The watchdog is enabled by default. (COP timeout is after 1024 cycles, and the clocksource is the internal 1 kHz clock)

My idee: reset the target before execute the init, but I can not reset the target before init …

other idee: disable Wdog before execute the init, but I can not write registers before init …

I hope someone can help

Regards,

Samuel
