Hey,
I am trying to implement an API to accuratly measure code samples running times.
I did a similar thing on an ARM Cortex M4 core, using a cycle counter register.
I cannot find a similar register in e200z4 core.
I've read about people using the decrementer register as a cycle counter.
I tried accessing this register using ASM_KEYWORD (Diab compiler), but it didn't assemble.
https://www.nxp.com/docs/en/reference-manual/e200z4RM.pdf
I then read the the MPG5748G does not have a decrementer register, even though it has 2 e200z4 cores?
MPC5748G with OS tick lower than 1ms (100us) - ChibiOS Free Embedded RTOS
What is the formal solution for cycle counting on this chip?
