Interrupts in i.MX6UL

[surendrajadhav]

Hello,

Let me know which pins of the i.MX6UL processor I can use for interrupts. I saw in one EVK board where they are using SNVS_TAMPER pins for interrupt input from Ethernet.

As there are no dedicated pins being observed, let me know if I can use SNVS_TAMPER pins for interrupt.

Regards,

Hello,

The i.MX6UL tamper pins are configured for GPIO or tamper functionality

via fuses. Please look athttps://community.nxp.com/thread/382019 

 Note : If TAMPER_PIN_DISABLE[1:0] fuse is programmed to "11 - disabled
TAMPER0-9 used as GPIO", then the tamper pins are in gpio mode, you do not
need to configure iomux.

  When in GPIO mode, the tamper pins can operate as interrupts sources.

Please use the i.MX6 Reference Manual, Chapter 26 [General Purpose Input/Output
(GPIO) ].

Have a great day,

Yuri
