# Examples using bootloader
|
||
|
|
|
||
|
|
Example for Raspberry Pi Pico demonstrating the bootloader. The example consists of application binaries, 'a'
|
||
|
|
which waits for 5 seconds before flashing the 'b' binary, which blinks the LED.
|
||
|
|
|
||
|
|
NOTE: The 'b' binary does not mark the new binary as active, so if you reset the device, it will roll back to the 'a' binary before automatically updating it again.
|
||
|
|
|
||
|
|
