Getting error while setting bitrate in CAN interface for android ICS

Hi Salih,

On which platform you are trying?

1. Have you downloaded latest iproute2 package and builded properly?

2. One point I can think of here is "can" is not integrated into iproute2, can you verify this?

Note: check the result of ip link help ;ensure that the TYPE field contains can

3. Make sure that the build images and execution images are correct? Execute iproute2 directly, go to the binaries folder and run this "./ip"

(OR)

One more option you have is, set bittimming parameters use "canconfig"

canconfig can0 bitrate 50000 ctrlmode triple-sampling on

 canconfig can0 start 

Thanks

Hi Anil,

Actually I am getting this error only when i will test in the android file system. If once I tested with this uImage in the Linux file system, it works properly.

I debugged the iproute2 application and found that there was an error in the file ip/iplink.c

I analysed and debugged inside the source code of this utility and compared with the Linux utility source. I found that the error was occurred in the system call dlsym().

        l = dlsym(dlh, buf);
        if (l == NULL)
                return NULL;

This function suppose to return some valid address. But in my case, its returning the NULL.

In Linux, its returning the proper address and it is passed in the case.

After I called this system call dlerror(), I am getting the below message:

 symbol not found:

Please suggest me any solution to solve this issue.
