I would like to use SEGGER systemview 2.5.2b with MCUXpresso, SDK_2.x_FRDM-K64F (2.4.2) and a basic freertos project for freedom K64 board.

I followed the SEGGER SystemView UserGuide UM08027 but didn’t succeed …

  1. Installed systemview for windows
  2. Run MCUXpresso debug my project (it works as expected)
  3. Run systemview

Start recording (choose USB, target= MK64FN1M0XXX12,interface: SWD 1429Khz, RTT Auto)

I receive the messages:

First popup: CPU_REG_Set(): Register 0 is already marked as valid

Second popup:      Failed to start recording

                              RTT Control Block not found

Could you help?
