occurrence of a data access at a specified address. (The addresses specified for each
instance can be different.) You must specify:
– the type of data access (Write, Read, Read/Write)
– the address where the Opcode Fetch must occur
– the address where the data access must occur
● Break on conditional stack write OR Opcode Fetch at given address. This option
allows you to break on the occurrence of either a write operation to the stack below a
specified address, or an Opcode Fetch at a specified address. You must specify:
– the maximum stack address below which the write operation must occur
– the address where the Opcode Fetch must occur
● Break on conditional stack write OR data access at given address. This option
allows you to break on the occurrence of either a write operation to the stack below a
specified address, or a data access at a specified address. You must specify:
– the type of data access (Write, Read, Read/Write)
– the address where the data access must occur
– the maximum stack address below which the write operation must occur
7.3 Creating a break on trigger input (TRIGIN)
You can connect an input signal via the IN trigger connector on the front panel of the ST
Micro Connect box. The input signal must be between 0 and 5 volts. The input signal causes
a break in the application only upon reception of a rising edge signal at TTL level.
The input trigger signal is only supported for in-circuit debugging over ICC with the ST Micro
Connect box.
7.4 In-circuit debugging in hot plug mode (SWIM only)
In-circuit debugging in hot plug mode is intended to allow you to take control over the
microcontroller on your application board while your application is running, without resetting
the microcontroller.
To start a debug session in hot plug mode, you must choose this option when you select
your debug instrument. This option is available when you do not have a loaded workspace,
and only with the SWIM RLink, SWIM STLink and SWIM STice choices for the debug
instrument.
To start a debug session in hot plug mode, follow these steps:
