ST10F276Z5 peripherals not supported by the

emulators

This section describes all emulation issues caused by peripherals not supported by the

ST10 emulators.

5.1

ST10F276Z5 Flash memory

Description: in emulation, the bond-out is running code from the RAM mapped into the

ST10 bond-out memory space.

ST10F276Z5 emulation impacts:

●

the automatic remapping of the Flash memory in normal or bootstrap mode is not

supported. This leads to have a specific software for each memory mapping.

●

the Flash memory specificities are not supported (Flash programming commands are

not recognized, reading any Flash memory register leads to undefined contents).

ST10F276Z5 Flash memory limitations: during emulation, some emulators do not protect

the emulated Flash memory against write access by the ST10F276Z5. The bond-out, when

properly configured, protects the internal Flash memory. Then, external hardware placed on

the emulated XFlash can protect it during emulation.

Please, contact your emulator provider to have more information on the Flash memory

support.

5.2

Bootstrap and Alternate Boot mode

Description: the ST10F276Z5 bootstrap modes cannot be supported by the emulator. The

ST10F276Z5 has a dual bootstrap via UART or CAN and supports alternate boot.

This limitation is not specific to the ST10F276Z5, it is also applicable to the ST10F269Zx.

ST10F276Z5 emulation impacts:

●

the dual boot is not supported

●

alternate bootstrap is not supported (ST10 bond-out does not decode Port0

configuration for alternate boot).

To debug the bootstrap software routines, it is required to have a specific software for this

mode. This specific software, loaded into the emulator memory, must have the same boot

software as the one inside the boot-Flash of the ST10F276Z5, and all the needed software

from the other blocks of the Flash memory.
