Comparing the old and the new bootstrap loader
The following tables summarizes the differences between the old ST10 (boot via UART only)
bootstrap and the new one (boot via UART or CAN).
Table 34.
Software aspects
As the CAN1 is needed, XPERCON register is configured by the bootstrap loader code and
bit XPEN of SYSCON is set. However, as long as the EINIT instruction is not executed (and
it is not in the bootstrap loader code), the settings can be modified. To do this, perform the
following steps:
●
●
●
Uses only 32 bytes in Dual-
Port RAM from 00’FA40h
Loads 32 bytes from UART
User selected Xperipherals
can be enabled during boot
(Step 3 or Step 4).
Old bootstrap loader
DIsable the XPeripherals by clearing XPEN in SYSCON register. Attention: If this part
of the code is located in XRAM, it will be disabled.
Enable the needed XPeripherals by writing the correct value in XPERCON register.
Set XPEN bit in SYSCON.
Software topics summary
Uses up to 128 bytes in
Dual-Port RAM from
00’FA40h
Loads 32 bytes from UART
(boot via UART mode)
Xperipherals selection is
fixed.
New bootstrap loader
For compatibility between boot via UART
and boot via CAN1, please avoid loading
the application software in the
00’FA60h/00’FABFh range.
Same files can be used for boot via
UART.
User can change the Xperipherals
selections through a specific code.
