官方故障排除步骤
[Cause of error] The HSCI data rate of 1 Gbit/s was preset in the configuration datum MP_dataRateHsci in CfgHardware. However, the HSCI system could not be switched to the 1 Gbit/s data rate. There might be connecting cables in the HSCI system that are not made for this data rate. [Error correction] Check the HSCI cable for suitability for the 1 Gbit/s data rate. In the configuration datum MP_dataRateHsci in CfgHardware, select the data rate 100 Mbit/s or “as fast as possible.”
