| 5 | 4 | laforge | * check out at91lib.git and osmo-sdr.git into the same ancestor directory |
| 6 | * change to osmo-sdr/firmware/sdr-test-project |
||
| 7 | * 'make flash' |
||
| 8 | * use rum-ba to flash it: |
||

| 16 | h2. Serial console |
||
| 17 | |||
| 18 | |||
| 19 | 1 | laforge | On the serial console, you can enter three types of commands: |
| 20 | 4 | laforge | * actions denoted by ! at the line end |
| 21 | * getting a value, denoted by a ? at the line end |
||
| 22 | * setting a value in key=value notation |
||
| 23 | 1 | laforge | |
| 24 | A list of commands can be obtained by entering ? on an empty line |
||
| 25 | |||
| 26 | Enter always re-sets the parser, so you can abort any unfinished command with enter |
