Problems with sdcard_twrk64f120m demo

[tomtalkington]

I am trying to run the sdcard_twrk64f120m demo in the MFS examples and when the SD card is inserted I see:

shell> Installing MFS over SD card driver...

Error while opening a:\ (UNKNOWN ERROR !!!)

Anyone seen / solved this before?

Hi Tom,

according to your error message

Error while opening a:\

it looks on problem with SD Card.

at the moment I tested the demo and on my side it works without problems.

Please, see the video which I attached you. (I skipped building project)

Please, did you try another SD Card? What file system do you use?

Best Regards,

Iva

Hello Iva,

Tried several SD Cards.  None worked. Then I inspected the hardware where I found my problem.  Cold solder joints on the SD Card connector pins!  Re-soldered them and all is well.

Thank you so much for your time and help.

Best regards,

Tom
