STM32F103C8T6正常运行的代码，直接平替GD32F103C8，CAN部分初始化异常，一直返回失败
uint8_t CAN_Init(CAN_TypeDef* CANx, CAN_InitTypeDef* CAN_InitStruct){
uint8_t InitStatus = CAN_InitStatus_Failed;

uint32_t wait_ack = 0x00000000;  /* Check theparameters*/assert_param(IS_CAN_ALL_PERIPH(CANx));assert_param(IS_FUNCTIONAL_STATE(CAN_InitStruct->CAN_TTCM));
assert_param(IS_FUNCTIONAL_STATE(CAN_InitStruct->CAN_ABOM));
assert_param(IS_FUNCTIONAL_STATE(CAN_InitStruct->CAN_AWUM));
assert_param(IS_FUNCTIONAL_STATE(CAN_InitStruct->CAN_NART));
assert_param(IS_FUNCTIONAL_STATE(CAN_InitStruct->CAN_RFLM));
assert_param(IS_FUNCTIONAL_STATE(CAN_InitStruct->CAN_TXFP));
assert_param(IS_CAN_MODE(CAN_InitStruct->CAN_Mode));
assert_param(IS_CAN_SJW(CAN_InitStruct->CAN_SJW));
assert_param(IS_CAN_BS1(CAN_InitStruct->CAN_BS1));
assert_param(IS_CAN_BS2(CAN_InitStruct->CAN_BS2));
assert_param(IS_CAN_PRESCALER(CAN_InitStruct->CAN_Prescaler));  /* Exit from sleep mode */
CANx->MCR &= (~(uint32_t)CAN_MCR_SLEEP);  /* Request initialisation */
CANx->MCR |= CAN_MCR_INRQ ;  /* Wait the acknowledge */
while (((CANx->MSR & CAN_MSR_INAK) != CAN_MSR_INAK) && (wait_ack != INAK_TIMEOUT))  { wait_ack++;  }  /* Check acknowledge */
if ((CANx->MSR & CAN_MSR_INAK) != CAN_MSR_INAK)
{ InitStatus = CAN_InitStatus_Failed;=====================卡在这个位置  }
请教各位，有遇到过吗？麻烦指导下，谢谢大家！
