Hi @PetervdPerk-NXP , > Unfortunely there wasn't a how to guide, but I tried to mimick the SIM sysview configuration Yes, the SIM configuration simply enables the configuration to ensure that the compilation can work normally. We will add a back-end based on file to save the system view stream on SIM platform, which is still under development > Regarding a ASM file optimized for ARMv7 SEGGER_RTT_ASM_ARMv7M.S, my workaround was to remove that from build system and use the fallback C file. Sorry to confuse you, I just tested the configuration under v8m, you can temporarily remove the optimization of v7m, I will try to fix this issue further > Some errors regarding missing up_perf_gettime and up_perf_getfreq function, I circumvented this by enabling CONFIG_TIMER_ARCH which implements these functions, but it seems that the sim config didn't require those. I have uploaded a new PR, they implemented cycle counter based on DWT, you can try this commit: https://github.com/apache/incubator-nuttx/pull/5850 In addition, you also need to initialize the CPU clock frequency in the board implement, eg: https://github.com/apache/incubator-nuttx/pull/5850/commits/b5edd67cc592a226c9b0fe32914ac5763c78eea9#diff-2e2c7b8e12a8db8218fd22d16f664621da802957420e528caf0c44d0307dc819R57 > do you have an idea on which interfaces I need implement/enable to get this fully to work? I think this should be caused by the cycle counter not working properly, please check whether up_perf_init() or up_perf_gettime() is working properly -- This is an automated message from the Apache Git Service.
