# Frequently Asked Questions

## Build Errors
|
|
|
|
### Flash Overflow
|
|
|
|
The amount of code that can be loaded onto a board is limited by the amount of flash memory it has.
|
|
When adding additional modules or code its possible that the addition exceeds the flash memory.
|
|
This will result in a "flash overflow". The upstream version will always build, but depending on what a developer adds it might overflow locally.
|
|
|
|
```sh
|
|
region `flash' overflowed by 12456 bytes
|
|
```
|
|
|
|
To remedy it, either use more recent hardware or remove modules from the build which are not essential to your use case.
|
|
The configuration is stored in **/PX4-Autopilot/boards/px4** (e.g. [PX4-Autopilot/boards/px4/fmu-v5/default.px4board](https://github.com/PX4/PX4-Autopilot/blob/main/boards/px4/fmu-v5/default.px4board)).
|
|
To remove a module, just comment it out:
|
|
|
|
```cmake
|
|
#tune_control
|
|
```
|
|
|
|
#### Identifying large memory consumers
|
|
|
|
The command below will list the largest static allocations:
|
|
|
|
```sh
|
|
arm-none-eabi-nm --size-sort --print-size --radix=dec build/px4_fmu-v5_default/px4_fmu-v5_default.elf | grep " [bBdD] "
|
|
```
|
|
|
|
## USB Errors
|
|
|
|
### The upload never succeeds
|
|
|
|
On Ubuntu, uninstall the modem manager:
|
|
|
|
```sh
|
|
sudo apt-get remove modemmanager
|
|
```
