T1040RDB DPAA Fman issue

[weizhao]

I have a T1040RDB, I  can run Linux 3.12 Kernel with Topaz Hypervisor with no issue.  However, when I try to run Linux 4.1 with same hardware device tree, Hypervisor device tree, and Topaz Hypervisor, I always got following error info:

      [ 2.485455] cpu1/1: ! MAJOR FM Error [CPU01, /localdisk/data/perforce/wezhao_t1040rdb/main/packages/linux-

The board still boot successfully, however, no Ethernet port (fm1-gb3, fm1-gb4) show up.  Any idea please ?

Thanks,

Hello Wei,

Would you please try whether there is problem to boot up Linux Kernel in the normal environment without Hypervisor?

Would you please provide your hv.dts and the target dts file?

Thanks,

Hello Wei,

I tried to compile your dts file in SDK 2.0 environment, however there was compilation problem. I suspect your dts file is not compatible with Linux Kernel 4.1.

Would you please try to use the dts file arch/powerpc/boot/dts/fsl/t1040d4rdb.dts(or t1040rdb.dts) provided in Linux Kernel source 4.1.

Thanks,

Yiping

Hi Yiping,

My hardware device tree file sending to you is generated from arch/powerpc/boot/dts/fsl/t1040rdb.dts as I am using t1040rdb board (not the DDR4 memory one). The only thing I modified is adding “fsl,P5040RDB” to both model and compatible so that I can reuse some code we added for P5040, please see the following:

Thanks,

Wei

Hello Wei,

Please use T1040RDB dts file provided in Linux Kernel 4.1 in arch/powerpc/boot/dts/fsl/t1040rdb.dts.

I verified t1040rdb.dts provided in SDK 2.0 working with Linux Kernel 4.1.8 on a T1040RDB DDR3 board without any problem.

Please refer to the attached log.

Please try the attached dtb file on your target board.

Have a great day,
TIC

Hi Yiping,

Sorry for replying later as I took few day off.

I still get same issue even without running Hypervisor. The hardware device tree and Hypervisor device tree files are attached. I used hardware device tree from Linux 4.1 (SDK 2.0) for t1040rdb boards. The hypervisor configuration tree from Hypervisor 1.3 for t10404rdb.

Thanks,

Wei
