Hi guys,

I am working with the board T2080RDB. I am using the operative system which is provided by NXP using Yocto Proyect and the sdk 2.0-1703.

My purpose is sending SRIO doorbells and messages by T2080 regardless of the ethernet frames.I only want to implement the SRIO transactions.I use the usdpaa-app according to the SDK document.First operation is to sending doorbells.The log is below:

According to the log,the probelm is there is not the /dev/rman-uio.

I edit the kernel as follows:

Device Drivers --->

            <*> Userspace I/O drivers --->

                            <*> Freescale Serial RapidIO support

            <*> Staging drivers --->

                             [*]  Freescale RapidIO Message Manager support

But it didn't work.There still isn't the /dev/rman-uio.

If any body has any lead over here so pls help me. suggestions would be highly appreciated.

Have a great day

According to T2080 DPAA User Manual, QMAN channel number 820h to 821h should be assigned to RMan.
Please add the following in the dts file t2081si-post.dtsi.
/include/ "qoriq-rman-0.dtsi"
rman: rman@1e0000 {
fsl,qman-channels-id = <0x820 0x821>;
};

Have a great day,
TIC
