Hi list, I want to use the gpiolib API in a routine that should poweroff the system (MPC5200B). I register my poweroff routine in the define_machine() macro as:
[...] .power_off = my_power_off, [...] In this routine I'm using gpio_request(...), gpio_direction_output(...) and gpio_set_value(...) ---- but nothing happens. When I set the GPIOs in the hard way (ioremap() + playing with the registers) the system switches off as expected. How to get some useful debug output at this late system state (printk does not work anymore)? Regards, Juergen -- Dipl.-Ing.
