Describe the bug

Hello, I am trying to port PX4 to a new board and found a problem in code.
In https://github.com/PX4/PX4-Autopilot/blob/c78389a855391adaf2dd05f58afcbc6b1500ff1a/platforms/nuttx/src/px4/common/px4_mtd.cpp#L203, the varible instance->n_partitions_current could be 0. And it triggers mcu divided by 0 assertion. Moreover, nblocks do not be used.

Borrowing the building, may I ask why the drone can take off in altitude mode, but in self stabilization mode, the command is temporarily rejected

Probably that your drone does not have a valid height sensor( baro, gps, lidar or others). BTW, please open an new issue if you have new question.
