Hi,
I have a custom C6A8167 board running Linux 2.6.37+. I am using ti-ezsdk_dm816x-evm_5_03_01_15 package. The following error message appears when loading the syslink.ko driver. If I check the /dev directory and I found that the syslinkipc_Notify is not there. The 15 other syslinkipc_xxxx are there in the /dev directory. Can some expert please tell me what is wrong with the syslink.ko module. Similar loading of cmemk.ko went OK without a problem.
Thanks,
Zhao
