///////////////////////////////////////////////////////////////////////////////
//
// USING THE DC BOOTLOADER
//
///////////////////////////////////////////////////////////////////////////////
1 : bl_reboot() // send to application, want DC2 to reset (in order to
// start the bootloader)
//
// NOTE: this function is NOT reliable !!! Sometimes it
// simply does not work, in which case bl_startBL,
// bl_checkBL and bl_isUp do not work as well.
// Alas, there is no feedback if bl_reboot worked!
//
// NOTE: this function can be called only once per
// minute, because once called again, the controller
// performs some self-checks consuming some time.
//
// NOTE: after a successful bl_reboot(), the device is
// waiting about 4 seconds in the bootloader. To stay in
// the bootloader, we have to send the command
// bl_startBL(), which is kind of a misnomer, as it
// should be bl_doNotLeaveBL().
//
2 : bl_startBL(): // send within 4s after DC power-on, otherwise
// bootloader is left.
//
// NOTE: a running bootloader is a MUST for the download
// process of a device controller firmware as it does
// the actual writing of the memory (the bl_reboot()
// from above erases the available memory).
//
3 : bl_check(): // send command to verify if bl is up
//
// NOTE: this command is kind of a request that we want
// to check if the bootloader is up. The device
// (actually the bootloader) responds with its version.
//
4 : bl_isUp(): // returns true if bl is up and running
//
// NOTE: we know what the bootloader version actually is
// as the bootloader does not change. By comparing the
// string received in the previous step with this known
// version string we know if the bootloader is up.
//
// NOTE FOR ALL PREVIOUS STEPS: execute them in their
// own slots each to be sure to receive any possible
// responds from the device.
//
5 : bl_sendAddress(blockNumber)
// send start address, nr of 64-byte block, start with 0
// will be sent only for following block-numbers:
// 0, 1024, 2048, 3072 and 4096, so basically every
// 64kByte.
// for other addresses nothing happens
6 : bl_wasSendingAddOK()
// return val: 0: no response by now
// 1: error
// 10: OK
7 : bl_sendDataBlock()
// send 64 byte from bin file
8 : bl_sendLastBlock()
// send this command after all data are transferred
9 : bl_wasSendingDataOK()
// return val: 0: no response by now
// 1: error
// 10: OK
10 : bl_stopBL() // leave bl and start (the new) application
//
// NOTE: this function MUST work under all conditions.
// Alas, there is no direct result for this command, so
// the only way of knowing it was successful is to ask
// the device if the bootloader is still running.
// There is no problem to repeat this command until the
// bootloader is really not running anymore.
