i want to use CAN transmitter from STM32F103. i have configured it using STM32cubeMX and programming using IAR workbench. i've observed the CAN status registers and it is showing CAN_TSR_TERR0 =1 and CAN_ESR_TEC =0x88.

[NSing.5]

CAN_ESR_LEC =0x05.

which means bit dominant error,

CAN_MCR_DBF bit is at 1.

how to trouble shoot it
