我也有个相似问题，请教一下。我用的是SDHC的8G卡，在SD_GetCSDRegister中发送CMD9之后一直接收不到数据起始令牌0XFE
[mw_shl_code=c,true] /*!< Send CMD9 (CSD register) or CMD10(CSD register) */
SD_SendCmd(SD_CMD_SEND_CSD, 0, 0xFF);
/*!< Wait for response in the R1 format (0x00 is no errors) */
if (!SD_GetResponse(SD_RESPONSE_NO_ERROR))
{
if (!SD_GetResponse(SD_START_DATA_SINGLE_BLOCK_READ))
{
for (i = 0; i < 16; i++)
{
/*!< Store CSD register value on CSD_Tab */
CSD_Tab = SD_ReadByte();[/mw_shl_code]
