The internal flash memory is divided into partitions of several uses. The exact partition sizes are stored in the U-Boot environment variable "mtdblocks", and depend on bad blocks of each device. Flashing the Neo 1973 updates partition contents.

The internal flash memory is divided into partitions of several uses. The exact partition sizes are stored in the U-Boot environment variable "mtdblocks", and depend on bad blocks of each device. Flashing the Neo 1973 updates partition contents.
