I have been using SystemView successfully for a project running FreeRTOS on a NXP Kinetis Cortex M0+ chip. Originally it was using FreeRTOS v9 but I have recently updated to FreeRTOS v10.0.1 - not sure if that is related to the problem. I have started having problems with the Timeline window scrolling erratically, with timestamps jumping between the correct timestamp and zero. The timestamps for items shown in the Events window and Terminal window are correct and scroll smoothly as new items arr…

I tried following the existing procedure (ie for FreeRTOS v9) to modify a FreeRTOS v10 installation, consisting of copying over the target source modules, adding SEGGER_SYSVIEW_Conf(); to main() and running the FreeRTOSV9_Core.patch over the v10 files. I encountered some minor errors during compilation indicating "xJustPeeking" was undeclared where used in SEGGER_SYSVIEW_FreeRTOS.h. This occurred in the "#define traceQUEUE_xxxx" lines 212 to 229. I replaced all of these defines with versions tak…

Hi Nino, Thanks for the update. We have noticed that the debug UART (virtual COM port) on the FRDM-KL28Z does not seem to work correctly when using the generic OpenSDA v2.1 firmware. Sometimes it adds a few random characters to the end of strings, sometimes it continuously sends out garbage characters. The board works fine with the DAPLink interface so we have reverted to that in the meantime. See attached examples (J-Link generic OpenSDA vs DAPLink rev 0242) - notice the additional characters "…

Hi Nino, I'm sorry to say that procedure does not work for me. It is what I have tried before several times, without success. But just to check, I have done them again, and reported the results below. - Connect FRDM Board to PC while holding reset button. Ok. - A Drive named BOOTLOADER showed up Board shows up as "MAINTENANCE". A device which appears as "BOOTLOADER" indicates it is running an outdated version of DapLink bootloader ! See the flow chart under "How to update your boards" at os.mbed…

I have a new FRDM-KL28Z dev board which comes with the default DAPLink bootloader and OpenSDA v2.2 firmware. I am having problems loading the current J-Link OpenSDA firmware on it. If I power the board up into bootloader mode, copy the latest J-Link firmware (from the "J-Link OpenSDA - Board-Specific Firmwares" page for the FRDM-KL28Z board) on to it, when the board restarts it is still running the original OpenSDA v2.2 firmware and a J-Link debug probe is not available. The best I have been abl…
