Start the Application
Requests from Host
Answer from Bootloader No answer is returned by the device.
Example
4266C–CAN–03/08
Start application with a reset
Start application with a jump
The flow described below allows to start the application directly from the bootloader upon a spe-
cific command reception.
Two options are possible:
•
•
Command Name
pulse generation
Start the application with a reset pulse generation (using watchdog).
When the device receives this command the watchdog is enabled and the bootloader enters
a waiting loop until the watchdog resets the device.
Take care that if an external reset chip is used the reset pulse in output may be wrong and in
this case the reset sequence is not correctly executed.
Start the application without reset
A jump at the address 0000h is used to start the application without reset.
at “address”
Start Application with reset pulse
Start Application without reset at address 0000h
