Please refer to the IOMUXC_SW_MUX_CTL_PAD_GPIO06 register field descriptions table on the Page 2068 of the i.MX6Dual/Quad Reference Manual Rev.5 document, available on the processor's Documentation web page:
The Table says that the pad is involved in a number of daisy chains. So, please check the configuration of all related IOMUXC registers, mentioned in the Table.
Have a great day,
Artur

hi Artur,
Thanks for reply!
Why need I concern daisy chains mode?The mode of mux I config is ALT5.
#dedine MX6Q_PAD_GPIO_6_GPIO_1_6
IOMUX_PAD(0x0600, 0x0230, 5, 0x0000,0,0)
In my opinion, when mux mode is ALT0 , ALT2 or ALT5,I should check daisy chains.
Please show me more details.
The wrong configuration of other pads, involved in daisy chain, can affect the GPIO06 pad operation as well. So, anyway, please check the configuration of other pads, involved in this daisy chain.
