我用G474的板子检测到Bit 7 BO: Bus_Off status,查找错误码是(然后咋办呀?):
101: Bit0Error: During the transmission of a message (or acknowledge bit, or active error
flag, or overload flag), the device wanted to send a dominant level (data or identifier bit logical
value 0), but the monitored bus value was recessive. During Bus_Off recovery this status is
set each time a sequence of 11 recessive bits has been monitored. This enables the CPU to
monitor the proceeding of the Bus_Off recovery sequence (indicating the bus is not stuck at
dominant or continuously disturbed). |
