Customer would like to manipulate ESAI0_TX0 as GPIO (LSIO_GPIO0_IO04) by sysfs, but doesn't work.
Then try to dump mux_mode of i.MX8X register ESAI0_TX0 via memtool to make sure setting is right.
Reference manual only shows offset 0x2_31c0h, but no base address of IOMUX.
So what is the memory map address of i.MX8X IOMUX?
Solved! Go to Solution.

Hello,
As for LSIO addresses, please use Table 2-4 (LSIO memory map)
of the i.MX 8DualX/8DualXPlus/8QuadXPlus Reference Manual
(Rev. 0, 05/2020).
Note, IOMUXD is programmed through the System Controller API
and is not programmed directly. Please see the API Reference
Guide for more information.
Regards,
Yuri.
