    Hi,

    In doorbell interrupt delay case, Are you getting other errors identified too, i.e. SPn_ERR_STAT, ERR_DET, SPn_ERR_DET?

    Better to use the latest PDK version SRIO driver and example for your testing(pdk_C6678_1_1_2_6). Please download the latest MCSDK 2.x for Keystone I devices(C6657/70/78) and the follow user guide here.

    Thanks,

    Hi Ganapathi,

      Thanks for your reply.

      I use pdk_C6678_1_1_2_6 to test.It is the same .The  value of SPn_ERR_STAT, ERR_DET, SPn_ERR_DET  at normal state  is same with delay state.DoorBell Delay ,Because the LSU context Bit of LSU_STAT_REG is not equal with LSU6 Bit.So it is block .Why is it block?Can you tell me?

    Thanks,

    Best Regards,
