Hardware to activate BSL
The hardware that activates the BSL during reset may be a simple pull-down resistor on
P0L.4 for systems that use this feature at every hardware reset. For systems that use the
bootstrap loader only temporarily, it may be preferable to use a switchable solution (via
jumper or an external signal).
CAN alternate function on Port4 lines is not activated if the user has selected eight address
segments (Port4 pins have three functions: I/O port, address segment and CAN). Boot via
CAN requires that four or less address segments are selected.
Figure 6
The device is reset with P0L.4 low.
The internal new bootstrap code runs on the ST10 and a first level user code is
downloaded from the external device, via the selected serial link (UART0 or CAN1).
The bootstrap code is contained in the device Test-Flash and is automatically run when
the device is reset with P0L.4 low. After loading a preselected number of bytes, the
ST10F276Z5 begins executing the downloaded program.
The first level user code runs on the ST10F276Z5. Typically, this first level user code is
another loader that downloads the application software into the device.
The loaded application software is now running.
