TrueSTUDIO printf output is limited

Hi there,

I've configured my TrueSTUDIO in the following way:

https://www.youtube.com/watch?v=qSzme7qcBb0, to redirect the output of my printf-function to console. It works, but the output is limited, sometimes if I want to output a bigger amount of characters it just cuts off the end. For example: I want to print a 32 Byte array, that works, but a 64 Byte array is cut off.

I work with a stm32f767zi and TrueSTUDIO. Short explanation of my configurations:

  • created a new syscalls.c
  • overwrite _write method (send_char)
  • enable swv in debugger
  • set swv slot 0 active in debugger mode
  • start trace
  • resume

I appreciate your help.

Thank you very much.

Best regards
