1. 使用220芯片自制的板卡

2. PCIe主设备为FT2000

3. 220端报错信息如下：

*ERROR*: TESTMOD: vpu_service/rpc_server.c@2575@handle_poll_result: chid 0  i 0 Poll returned error event 8  cnt 1 devfd 13 enable_poll 1

*ERROR*: TESTMOD: vpu_service/rpc_server.c@1457@abort_decode: Failed to compulsory stop the decoder.

不知道这代表者什么？
