### Debug Log
|
||||
|
||||
### Log Level
|
||||
|
||||
Should you have an issue running example and/or submitting an bug report. You could enable TinyUSB built-in debug logging with optional `LOG=`. LOG=1 will only print out error message, LOG=2 print more information with on-going events. LOG=3 or higher is not used yet.
|
||||
|
||||
```
|
||||
$ make LOG=2 BOARD=feather_nrf52840_express all
|
||||
```
|
||||
|
||||
### Logger
|
||||
|
||||
By default log message is printed via on-board UART which is slow and take lots of CPU time comparing to USB speed. If your board support on-board/external JLink debugger, it would be more efficient to use it with RTT protocol for logging. To do that add option `LOGGER=rtt` to build command e.g
|
||||
|
||||
```
|
||||
$ make LOG=2 LOGGER=rtt BOARD=feather_nrf52840_express all
|
||||
```
|
||||
|
||||
## Flash
|
||||
|
||||
`flash` target will use the on-board debugger (jlink/cmsisdap/stlink/dfu) to flash the binary. We should install those debugger/programmer software in advance. Furthermore, since external jlink can be used with most of the board, there is also `flash-jlink` target for your convenience.
|
||||
`flash` target will use the default on-board debugger (jlink/cmsisdap/stlink/dfu) to flash the binary, please install those support software in advance. Some board use bootloader/DFU via serial which is required to pass to make command
|
||||
|
||||
```
|

$ make BOARD=feather_nrf52840_express flash

debugger memory accesses while the CPU is running.
