Now you have to test whether the microSD card is compatible. To do this, type the following command
Ls -l / sys / block | Grep mmc
There are now a series of many entries. Look for a line with the "mmc0: 0001" entry, if you find it, you can use the microSD card. If you have an entry with zb. "Mmc0: 59b4", you can stop or test another microSD card. ?
