Lauterbach access to the iomuxd registers for pinout configuration

[matteo-facchinetti]

Hi,

I'm using Lauterbach with the i.MX8QM and I have a problems to write to the iomuxd registers to modify on fly the pinout configuration. I can only read them.

For what I have understood, I'm expecting to have the possibility to change these registers with the JTAG.
Is it right?
Is there any other registers to change before, to grant the write access to the IOMUXD pin conf register?

Any hint is welcome.

Thanks in advance.
Matteo

Hi Matteo

Are you trying this right out of reset or after you run your firmware (u-boot/kernel etc) up to certain point.

I am using a different JTAG probe (BDI3000) but I can try this in the coming weeks when I have access to iMX8M board.
