Broken microSD slot on new DuetWifi
-
Hello,
i just got my new DuetWifi today and tried to set it up.
But after setting up the Wifi, i found, that the board isn't able to access the provided sd card.
I tried to update the firmware, but that was not possible from the wifi page (probably, because the firmware wants to cache the new firmware on sd card). Therefore, i updated the firmware with the Atmel tool via USB, which worked fine, but didn't help with the sd card.The firmware says:
Cannot initialise SD card 0: Card is unusableRepRapFirmware for Duet WiFi Version 1.18.1 dated 2017-04-09
Executing default.g (no configuration file found)…Error, not foundWhen booting without sd card it says
Cannot initialise SD card 0: Card not foundRepRapFirmware for Duet WiFi Version 1.18.1 dated 2017-04-09
Executing default.g (no configuration file found)...Error, not foundAt least it detects if a card is present in the slot.
So i hooked up my oszilloscope to the pins of the sd card slot.
All pins show activity during boot, except for pin 2 (Data3).
I also tested the connection between the contacts in the sd card slot and the smd pads on the pcb with a fine wire.
Again, no connection on pin 2. So if the firmware accesses the sd card in 4-bit mode it is no wonder, that it is not happy with the data it gets.Seems like my DuetWifi was delivered with a broken sd card slot. Probably its possible to exchange the slot, but i would rather not do this on a brand new board.
I suggest, we arrange a replacement of the board.Regards,

Hi Pascal
Have you tried a different SD card?

Yes, I tried with a different card.
I also checked both sd cards with chkdsk, and reformatted one card with FAT32 with 32k clusters.
No success, same error. -
Hi Pascal
Please contact your reseller for a warranty exchange referencing this forum thread, if you bought it direct from Duet3d.com then please send me an email referencing your order number.
