8MMINILPD4-EVK Schematic question for PCA6416APW routing

[jefflfree]

Referring to the base board schematic for i.mx8m mini how is PCA6416APW on page 5 used to interrupt the M4? The board schematic shows PCA6416APW on page 5 the INT pin going to IOEXP_nINT which is connected to GPIO1_IO12. However, GPIO1_IO12 is not connected to M4 interrupt m4_nmi. Rather GPIO1_IO05 is.

Hi Jeff

GPIO1_IO12 can be used to interrupt M4 as described in sect.7.1.3 CM4 interrupts

i.MX 8M Mini Applications Processor Reference Manual

in particular IRQ64- Combined interrupt indication for GPIO1 signal 0 throughout 15

Best regards
igor
