Jan,
Thanks for the support! So I have bought the SD card reader shown in the tutorial, which is arriving tomorrow. Do you still think I will need replace the declaration with code similar to what you provided above? I ask because I can’t find the file “mcc_common_setup.cpp” that you linked to in any of my project’s directories (The demo program is named “example-Ethernet-mbed-Cloud-connect”). Whatever the case, I’ll try the code unmodified and see if it can access the card reader. It appears everything else is working:
Starting Simple Mbed Cloud Client example Connecting to the network using Ethernet... Connected to the network successfully. IP address: 168.200.176.135 [Simple Cloud Client] Autoformatting the storage. [Simple Cloud Client] Autoformatting failed with error -5 Initializing Mbed Cloud Client failed (1)
Excited to try it out tomorrow night + whatever you might recommend. Until then, fingers crossed!
