Linux/AM3358: PVR error

JHi

Part Number: AM3358

Tool/software: Linux

So I'm trying to get the eglfs to work, but I'm having problems. I'm using the newest SDK 4.3 and I have compiled the pvrsrvkm module. I'm able to load it with ins mod without any problems, but when I try to start the PVR initialisation server I'll get the following error:

Hello JHi,

You need to stop weston.
root@am335x-evm:~# /etc/init.d/weston stop

Best regards,

I'm using the base image and there is no weston. I have to use the base one because full image is too big for NAND.

I have also checked the libraries with ldd:

        libdl.so.2 => /lib/libdl.so.2 (0xdeadbeef)

I did made ldconfig after inserting the libraries.

And the pvr libraries (am I missing something?)

pvrsrvctl --start --no-module fails and it is not already initialized. What is the dmesg saying, "PVR_K:(Error): BridgedDispatchKM: Driver initialisation not completed yet" or else? Seems you incorrectly compiled the pvrsrvkm.ko. Can you post the output of modinfo pvrsrvkm command and attach your pvrsrvkm.ko?

See this:

alias: of:N*T*Cti,dra7-sgx544

You built it for dra7-sgx544, not for am3352-sgx530.

How can I build the correct one? I compiled the ti-sgx-ddk-km-1.14.3699939/eurasia_km/eurasiacon/build/linux2/omap_linux

By defining TARGET_PRODUCT=ti335x
