I'm trying to reprogramm a ST10F269-T6 device which is already mounted on a circuit. The St10 MCU is monitored by a L4969 device(system voltage regulator with a CAN Transceiver). I'm failing to get the MCU in Bootstrape mode. The problem is probably the watchdog on the L4969 device. How best can I deactivate this watchdog.

thank you!

I really don't know the L4969, but try this:

The RESET state of the ST10 IO pins is HiZ. So trigger your watchdog input with an external oscillator and enter an undisturbed boot.

hope it helps...
