The current flash memory configuration is as follows.


​

Bootloader

The boot loader area is set at 64 kB, but the final binary capacity is 20.8 kB.

void callback_linkup(bool linkup)
{
gMutex.lock();
clear();
gMutex.unlock();

Led::setRgb(0, 0, 0);

if(linkup) // run when the network is connected
{
gFq.lock();
gFq.stop();
gFq.clear();
gFq.add(task::program::connectingToServer);
gFq.add(task::program::checkFirmwareFromServer);
gFq.add(task::program::programNewFirmware);
gFq.add(task::program::finish);
gFq.start();
gFq.unlock();
}
else // Run when network is disconnected
{
gFq.lock();
gFq.stop();
gFq.clear();
gFq.unlock();
}
}
The above callback_linkup function is called when the network is connected or disconnected. Items registered in the gFq.add() function are performed as follows.

While the > connectingToServer() function is performed, the red LED flashes and attempts to connect to the server.

> While the checkFirmwareFromServer() function is performed, the yellow LED flashes and checks that the server has ready firmware.

> Download the firmware with a flashing green LED while the programNewFirmware() function is being performed.

Wait for the blue LED to flash and power off while the > finish() function is performed.
