SEGGER SystemView with RELAX Kit without OS

Hello
Did anybody succeed to use SEGGER SystemView with RELAX Kit without OS using Infineon DAVE IDE?
I configured it according to SEGGER manual, but when I start to record, my application stops in file startup_XMC4500.s:

C Source Code

/* ================== START OF VECTOR ROUTINES ============================= */
.align 1
.thumb
/* Reset Handler */
.thumb_func
.globl Reset_Handler
.type Reset_Handler, %function
Reset_Handler:
ldr sp,=__initial_sp
#ifndef __SKIP_SYSTEM_INIT
ldr r0, =SystemInit
blx r0
#endif

Display All

I used the supplied configuration in file SEGGER_SYSVIEW_Config_NoOS.c. Maybe something should be changed?

Hi,

To be able to connect to the XMC4500 J-Link has to do a reset of the device.

Does SystemView work when you let it run after it hit the breakpoint in the reset handler?

To work around this when a debugger (i.e. DAVE) is already attached to the target,
you can in SystemView configure the device as Cortex-M4 and add the RTT Control Block search address manually.
Then J-Link should be able to do the second connection to the device without a reset.

Best regards
Johannes

Hi

How can I determine values for RTT Control Block address?

Hi,

You can check the address of _SEGGER_RTT with your debugger/IDE.

Best regards
