MIMXRT1024 EVk Enet interrupt mapping

Hi All,

In the demo example of lwip ping on the evk kit mimxrt1024. Gpio1 22 is used as interrupt pin for enet. How is mapping of this to microcontroller number for enet interrupt 114 done. Also gpio1 4 is used for reset but i dont see both used in phy nor enet drivers anywhere. Thanks.

Hi @sbabu ，

Yes, it seems GPIO1_4 and GPIO1_22 is not used by software.

Regards,

Jing

Hi @jingpan , They are used. Please see BOARD_InitPins() in pin_mux.c Thanks, Babu
