 If the board does not provide a MTD device, a MTD device can be emulated in RAM
 for testing using module `mtd_emulated`:
 ```
-USEMODULE=mtd_emulated BAORD=... make ...
+USEMODULE=mtd_emulated BOARD=... make ...
 ```
 The emulated MTD device has by default 64 sectors with 4 pages of 128 bytes
 each, the minimum size to be able to create a partition with FAT file system.
 These default parameters can be overridden e.g. by `SECTOR_COUNT`,
 `PAGES_PER_SECTOR` and `PAGE_SIZE`:
 ```
-CFLAGS='-DSECTOR_COUNT=128' USEMODULE=mtd_emulated BAORD=... make ...
+CFLAGS='-DSECTOR_COUNT=128' USEMODULE=mtd_emulated BOARD=... make ...
 ```
 
 **Notes:** Depending on the MTD device and the USB speed, this operation can take some times.
