Power group in pinmux conflict

[matt67]

Hi there,

We are using pintool to assign pad of an i.mx8mm and dealing with 1.8 and 3.3 voltage domains.

We uses by example GPIO1_IO10 PAD as GPIO1_IO10  in powergroup NVCC_GPIO1 suplied in 1.8V (we wan this GPIO in 1.8V)

We also use the pad ENET_RD2 in alternate GPIO1_IO28 (we wan this GPIO in 3.3V) supplied by NVCC_ENET in 3.3V and a warning is appearing about a potential conflict, I cant figure out clearly in the Reference Manual if this is a real issue or not.

Is it a mistake to assign the pad as shown ?

Thank you,

Hi matt67

there is no conflict and ENET_RD2 can be used with NVCC_ENET at 3.3V ,

one can look at Table 64. i.MX 8M Mini 14 x 14 mm functional contact assignments

"Power group" column :

i.MX 8M Mini Applications Processor Datasheet for Consumer Products

Best regards
igor
