i.MX IOMUX when device tree does not set its function.

satoshishimoda — Fri, 09 Sep 2016 06:53:55 GMT

Hi community,

I have a question about i.MX Linux BSP.
I want to know what IOMUX is selected if I don't set it by device tree.
Is the initial setting written in datasheet selected?
(e.g. For i.MX6UL CSI_DATA00 pad, is CSI_DATA00 selected as datasheet Table 95 if no function is set by device tree?)

Best Regards,
Satoshi Shimoda

Hi Satoshi

>I want to know what IOMUX is selected if I don't set it by device tree.

IOMUX has settings left from uboot.

If uboot does not set them, then left from chip reset settings,

"initial setting written in datasheet selected".

Best regards
igor
