Ok, they're the same and everything works fine. Except one mitx-specific thing though... on the power-off call I can see that MCU is driving its PTA1 pin low as expected, but the board doesn't turn off. PTA1 pin is wired to the J19 jumper pin1, pin2 is PORESET# and pin3 is RESET#. It doesn't work in both [1-2] and [2-3] positions... This is surely not a software issue though. And just in case, on the board I have the PWR button isn't functional, so this is hw issues (or just need to find another jumper somewhere ;-). Updated patch follows. - - - - From: Anton Vorontsov <[EMAIL PROTECTED]> Subject: [POWERPC] mpc8349emitx/mpc837xrdb: add support for MCU MCU is an external Freescale MC9S08QG8 microcontroller, mainly used to provide soft power-off function, but also exports two GPIOs (wired to the LEDs, but also available from the external headers).
