5.12.1.1 AppendToLogFile
This command can be used to configure the AppendToLogFile feature. If enabled, new
log data will always be appended to an existing logfile. Otherwise, each time a new
connection will be opened, existing log data will be overwritten. By default new log
data will not be always appended to an existing logfile.
Syntax
AppendToLogFile = 0 | 1
Example
AppendToLogFile 1 // Enables AppendToLogFile
5.12.1.2 CORESIGHT_SetIndexAHBAPToUse
This command is used to select a specific AHB-AP to be used when connected to an
ARM Cortex-M device. Usually, it is not necessary to explicitly select an AHB-AP to be
used, as J-Link auto-detects the AP automatically. For multi-core systems with multi-
ple AHB-APs it might be necessary.
The index selected here is an absolute index. For example, if the connected target
provides the following AP layout:
• AP[0]: AHB-AP
• AP[1]: APB-AP
• AP[2]: AHB-AP
•AP[3]: JTAG-AP
In order to select the second AHB-AP to be used, use "2" as index.
Syntax
CORESIGHT_SetIndexAHBAPToUse = <Index>
Example
CORESIGHT_SetIndexAHBAPToUse = 2
5.12.1.3 CORESIGHT_SetIndexAPBAPToUse
This command is used to select a specific APB-AP to be used when connected to an
ARM Cortex-A or Cortex-R device. Usually, it is not necessary to explicitly select an
AHB-AP to be used, as J-Link auto-detects the AP automatically. For multi-core sys-
tems with multiple APB-APs it might be necessary.
The index selected here is an absolute index. For example, if the connected target
provides the following AP layout:
• AP[0]: APB-AP
• AP[1]: AHB-AP
• AP[2]: APB-AP
•AP[3]: JTAG-AP
In order to select the second APB-AP to be used, use "2" as index.
Syntax
CORESIGHT_SetIndexAPBAPToUse = <Index>
