Using Logic Analyzer

Hello
I want to use logic analyzer .
When i try to add signals of my GPIO
thats GPIOB (STM32) i get error message as Unknown signals
What can be added?
Could anyone let me know pls

Thanks

Use the example Blinky_ULp from e. g. Keil\Arm\Boards\Keil\MCBSTM32F400.

But for SWO trace there the ini file STM32_SWO.INI is not correct.

Use the following INI file:

FUNC void DebugSetup (void) {
  _WDWORD(0x40023830, _RDWORD(0x40023830) | 0x00000002); // RCC_AHB1ENR:   IO port B clock enable
  _WDWORD(0x40020400, 0x00000080);                       // GPIOB_MODER:   PB3 = Alternate function mode
  _WDWORD(0x40020408, 0x000000C0);                       // GPIOB_OSPEEDR: PB3 = 100 MHz speed
  _WDWORD(0x4002040C, 0x00000000);                       // GPIOB_PUPDR:   PB3 = No Pull-up/Pull-down
  _WDWORD(0x40020420, 0x00000000);                       // GPIOB_AFRL:    PB3 = AF0
// <h> Debug MCU Configuration
//   <o1.0>    DBG_SLEEP      Debug Sleep Mode
//   <o1.1>    DBG_STOP       Debug Stop Mode
//   <o1.2>    DBG_STANDBY    Debug Standby Mode
//   <o1.5>    TRACE_IOEN     Trace I/O Enable
//   <o1.6..7> TRACE_MODE     Trace Mode
//             <0=> Asynchronous
//             <1=> Synchronous: TRACEDATA Size 1
//             <2=> Synchronous: TRACEDATA Size 2
//             <3=> Synchronous: TRACEDATA Size 4
// </h>
  _WDWORD(0xE0042004, 0x00000027);  // DBGMCU_CR
}

DebugSetup();                       // Debugger Setup

/*-------------------------------------------------------------------
** Execute upon software RESET
**-----------------------------------------------------------------*/
FUNC void OnResetExec(void)  {
  DebugSetup();
}
