When I try to read i2c controller register from u-boot shell using md command on imx8mmevk board it causes exception and resets the board, no variant of md command like md.b, md.w etc is working
u-boot=> md 0x30a20000

Similarly when I try to access the I2C registers from linux user space using NXP's memtool, it causes board freeze,
root@imx8mm-lpddr4-evk:~# memtool I2C1.I2CR
Above command results into board hang.
What could be the possible reasons for above behavior?
