Hi,

I can request SPDIF PHY memory region, and ioremap also ok. but when try to read/write any one of SPDIF registers. The Linux system became no network connection, and no reaction on the terminator. seemly Linux dead.

 

Kernel log:

Request memRegion region Phy: 0x02004000 Size: 0x00004000
spdif_ioremap: Request memRegion region SPIDF ok.
spdif IRQ is ( 84)

 

I see the iomuxc setup a lot of the PADs.

Is there any setting of the PADs will impact the SPDIF registers access?

Or other configuration of the SOC impact the SPDIF access.

 

My system is not using the Freescale's SPDIF driver for audio.

Processor is : i.MX6QL

Linux version 3.18.13

 

Best Regards
