The log is "Waiting for root device PARTUUID=6065f35f-02... ".

Are you not seeing this error any more ?

Can you share me the more details on this 

Which emmc part you are using ?

Help share the full logs .

Yes, the problem no longer appears after I modified the driver code.

The EMMC we use is from Sandisk.

Hi Tao 

1. How many units are showing this failure? 
2. Is failure only happening at -40C or do you see it across a range of temperature?
3. If you boot up the failing device at RT and then bring it down to CT does it function properly?
4. Please read out SS_PHY_CTRL_1_REG and SS_PHY_STAT_1_REG when hang happened
5. Please check the resistor value on the MMC0_CALPAD pin is still 10 kohms +/-1% as mentioned in DM under the failure condition

Hi, Diwakar

1. Three samples have experienced this issue.

2. The lower the temperature, the higher the frequency of recurrence of this problem. After the temperature rises, this problem no longer occurs.

3. No, this problem occurs during the startup process, and once the startup is completed, there will be no problem.

4. How can I read the values of these two registers? I couldn't find the relevant fields in the SDK. Do I need to look up the EMMC chip manual? At present, I only have the data manual, which does not include these two fields.

5. I will notify our hardware colleagues to confirm this matter.

Best regards,

Tao

Regarding this question. I have attached in a screenshot the addresses where you read the registers that Diwakar recommended which I found in the MMCSD registers doc.
