Hi Sir,
As I knew, we can use below rule to convert gpio pin of i.MX6 to GPIO number.
(GPIO group x 32) + pin number = GPIO number of linux
Is it the same as i.MX8? It seems not the same. For example:
GPIO4_IO19 is gpio-371 of linux.
Do you know why?
Best regards
Kevin
Hello, Kevin,
>>Is it the same as i.MX8?
yes, iMX8MQ's GPIOs are same as those of i.MX6. You can check "arch/arm/mach-imx/hardware.h" .
For example GPIO4_19, should be (4-1)x32 + 19 =115.
Have a nice day!
