Generating dts file for imx-93

Hi team,

I had a i.MX-93(11x11) custom board, as a part of generating dts file. I'm using imx config tool. I had selected the processor not the board and with exact part no and package, particularly selected core-A55 with KSDK-2. But after all steps at code preview dts file generating for M-33 instead of A-55. please find the pictures attached below and suggest me changes need to done.

And I had reference imx-93 EVK kit, if I select isl-imx93-11x11 at boards it is showing cortex-a55.dts file.

Thanks

Robbi.

Thanks @joanxie ,

Now I'm able to get dts file for core A-55, and I had understood pin-multiplexing of dts file, how pin is assigned to pad using ALT functionality and daisy chain register.

This is the macro generated for LPUART4_RX functionality assigned to pin ENET2_RD0

But what is this 0x31e.

#define MX93_PAD_ENET2_RD0__LPUART4_RX	0x00F8 0x02A8 0x0424 0x1

MX93_PAD_ENET2_RD0__LPUART4_RX			0x31e

Is this 0x31 is any reset value.

Thanks

Robbi

you can refer to the register named SW_PAD_CTL_PAD_ENET2_RD0 from imx93 reference manual
