Hi,

I'm evaluation the use of JLink for ARM Cortex-A35 4CPU using JLink Plus.
Connection fails because it doesn't find CTI. I assume I need to manually set the addresses of the debug port, CTI, ETB, etc, but could not find any suitable command.

I could not find a useful example in the sample directory as well.

Is there a script file I can use as guidelines?

The next step is to test SDK based automation, so if you have any sample project it will be useful as well.

Thank you!
Hila

Thank you Simon, It seems like a very good starting point because "my" A35 is very much like this one, it's a Quad core but with only one cluster (this one has two).


Still I get the following error:

onnecting to target via JTAG
ConfigTargetSettings() start
ConfigTargetSettings() end - Took 26us
TotalIRLen = ?, IRPrint = 0x..FFFFFFFFFFFFFFFFFFFFFFF1
Failed to identify target. Resetting via Reset pin and trying again.
ConfigTargetSettings() start
ConfigTargetSettings() end - Took 10us
TotalIRLen = ?, IRPrint = 0x..FFFFFFFFFFFFFFFFFFFFFFF1
Error occurred: Could not connect to the target device.

Is it possible that my JLink Plus doesn't support A35?


Here is my script after modification:

__constant U32 _INDEX_AHB_AP_SYSTEM = 0; // AHB-AP connected to system bus with access to all peripherals etc.
__constant U32 _INDEX_APB_AP_CORTEX_A = 1; // Index of AP that identifies the APB-AP that is connected to the Cortex-A cores

__constant U32 _APB_ADDR_DBGREGS_A35_0 = 0x80090000;
__constant U32 _APB_ADDR_DBGREGS_A35_1 = 0x80092000;
__constant U32 _APB_ADDR_DBGREGS_A35_2 = 0x80094000;
__constant U32 _APB_ADDR_DBGREGS_A35_3 = 0x80096000;
//
// USER CONFIGURABLE
//
U32 _Index_APCore = _INDEX_APB_AP_CORTEX_A;
U32 _Addr_DBGREGS = _APB_ADDR_DBGREGS_A35_0;
const char* _sExecCTIBaseAddr = "CORESIGHT_SetCSCTICoreBaseAddr=0x80098000";

JLINK_CPU = CORTEX_A35;
