In Overo.h I find the following entrys:
These twp GPIO I am able to control the output via echo 1> gpio64/value.
MUX_VAL(CP(GPMC_WAIT2), (IEN | PTU | EN | M4)) /*GPIO_64*/\
/* - SMSC911X_NRES*/\
MUX_VAL(CP(I2C2_SCL), (IEN | PTU | EN | M4))
/*GPIO_168*/\ /* - USBH_CPEN*/\
These two I can’t control. I am to assume that the issue here is to change
the DIS to EN and they should be good to go?
MUX_VAL(CP(GPMC_WAIT3), (IEN | PTU | DIS | M4)) /*GPIO_65*/\
MUX_VAL(CP(MCSPI1_CS2), (IEN | PTU | DIS | M4)) /*GPIO_176
*/\ /* - LAN_INTR */\
I looked in the board-overo.c file and found nothing that looked GPIO
numbers or setting for individual GPIO’s.
So is the process to change these two entrys for 65 and 176 and then create
a new image? Then move this image over to the overo board and reboot? I
however couldn’t find any reference to gpio 66,67,68,69 in the .h files. How
does one configure these?
Thanks for the help.
