mmc not working: nuc980-fmi: no support for card's volts #23

Closed tonyho closed 4 years ago

tonyho commented 4 years ago

I have design a board refering the NUC980 reference board shematic, but the TF/MMC is not working. My schematic is: SD

When I insert the mmc/TF, the log is:

mmc0: error -110 whilst initialising SD card

I guess this is caused by no Pull-up in CLK signal line, so I added a 5.1KΩ Resistor to pull up the CLK , but:

I tried 3 cards, still failed:

With the 4G Panasonic TF card:

[ 518.470033] SD time-out cmd=51 blksz=8 [ 518.473774] mmc0: unrecognised SCR structure version 12 [ 518.478958] mmc0: error -22 whilst initialising SD card

While the SanDisk 8GB TF card:

# [  316.900049] SD time-out cmd=51 blksz=8
[  316.903791] mmc0: invalid bus width
[  316.907249] mmc0: error -22 whilst initialising SD card

Also I tried a SanDisk Ultra Micro HC I, Class 10 A1, 16GB, which is not working with logs:

[  719.830049] SD time-out cmd=51 blksz=8
[  719.833791] mmc0: unrecognised SCR structure version 2
[  719.838891] mmc0: error -22 whilst initialising SD card

All the cards can be probe OK as sda device when inserted into NUC980 USB Host with a SD Card Reader.

Question:

Hi,

Try remove 100R and short circuit. No need to pull up CLK.

Sincerely,

Sincerely,

Thanks for the quickly reply. I tried to remove the 100R, and short circuit. And add some extra log information :

The kernel not detect the mmcblk partition with mmc0: SD Status: Invalid Allocation Unit size, but it does detect the size of SD card correctly, is any further suggestion?
Should I remove the pull up 5.1K resistor of the CLK line?

yachen commented 4 years ago

Yes, please test again with the 5.1k removed. Thanks.

tonyho commented 4 years ago

Yes, please test again with the 5.1k removed. Thanks.

I removed the 5.1K but stille not working:

Does the SD PC pins share with other function on your board? Can you replace C21 with a 10uF capacitor and test again?

  1. Can you replace C21 with a 10uF capacitor and test again? --> I tried, same result. Except adding a 10uF, I also tried to add a 220uF capacitor, but still the same result.

--> You mean the CD pin?  No.

Hi, Can you check the voltage level of PC12? Wonder why there's always a card remove message before kernel trying to detect the card type.

The card remove message is printed when I remove the mmc card.

What about other Port C pins (such as SD DATx/CMD/CLK), are they shared with other function on your board? It's difficult for us to check this issue remotely without your hardware. Who's your distributor in ShangHai? Can you ask them to check your hardware?

Does the SD PC pins share with other function on your board? --> You mean the CD pin? No.

Thanks for such a long support in Github issue, I think the root case for this is caused by the hardware. We tried to manufact 2 more board, and both of them without this issue. So thanks all your reply, and I will close this issue.

We buy the NUC980 for a remote distributor in ShenZhen not in Shanghai. Also hope that the NUC would have a wiki or discussion forum for customers.

nuc980 SD有两个SD0_nCD，一个PB8 一个PC12，怎么配置用哪一个引脚呢？
