We had this exact situation with our system basis chip (MC33989) watchdog resetting the processor during debugging with P&Es BDM Multilink. We simply placed a large resistor (100K) between the reset chip and HC12/BDM reset line. It allows the BDM pod to "overdrive" whatever the reset chip is trying to do during debugging and with the BDM pod disconnected

Recently I have expanded my Bootloader...

My understanding is that by changeing the PPAGE register (0x30) among 3C, 3D, 3E, and 3F, I should be able to view those pages. But
