Hi Lars,
Yes I verified, IO Expander is connected through I2C bus. And luckily there are 2 GPIOs that are connected to the Quark SoC, of which one of them is BUSY, the other one is unused. I will hook up CONVST for this.
So while calling gpio_set_value() I will have to use gpio_set_can_sleep() for doing RESET [as it's connected through IO Expander] and for CONVST gpio_set_value() will work right?
I checked with #cat /sys/kernel/debug/gpio
It showed
GPIOs 8 - 15 belong to Intel Quark
GPIOs 16 - 55, cy8c9540a, can sleep
so CONVST of connected to SoC directly it should be possible to work with triggers right?
Thanks Lars, I will try this out.
