RE: NRF52DK stops without the debagging processes turned on?

Hello Jørgen

Thank you for your help. Indeed, the RTT is used to print out the values that are obtain from the sensor.

Previous configuration:

//
  // Configure J-Scope RTT buffer for THREE unsigned ints
  //
  SEGGER_RTT_ConfigUpBuffer(JS_RTT_Channel, "JScope_U4U4U4", &JS_RTT_UpBuffer[0], sizeof(JS_RTT_UpBuffer), SEGGER_RTT_MODE_BLOCK_IF_FIFO_FULL);

And current configuration:

 SEGGER_RTT_ConfigUpBuffer(JS_RTT_Channel, "JScope_U4U4U4", &JS_RTT_UpBuffer[0], sizeof(JS_RTT_UpBuffer), SEGGER_RTT_MODE_NO_BLOCK_SKIP);

This is now working!

Best.

Hi,

Are you using RTT logging? If you do, have you configured this to BLOCK_IF_FIFO_FULL in your sdk_config.h file?

// <o> SEGGER_RTT_CONFIG_DEFAULT_MODE  - RTT behavior if the buffer is full.
 

// <i> The following modes are supported:
// <i> - SKIP  - Do not block, output nothing.
// <i> - TRIM  - Do not block, output as much as fits.
// <i> - BLOCK - Wait until there is space in the buffer.
// <0=> SKIP 
// <1=> TRIM 
// <2=> BLOCK_IF_FIFO_FULL 

#ifndef SEGGER_RTT_CONFIG_DEFAULT_MODE
#define SEGGER_RTT_CONFIG_DEFAULT_MODE 0
#endif

If not, what are you doing in your application? Is there any errors reported before the "freeze"?

Best regards,
Jørgen
