    Hi, I was using following method to read clock in cortex-a15:        static void readticks(unsigned int *result)         {             struct timeval t;             unsigned int cc;             if (!enabled...
  • EDSCR err bit set after a write to EDITR
    Hi, I have a very similar question to the resolved entry " reason for ARMv8 EDSCR err bit set ". So I try to follow that to give the state information. Cortex-57 JTAG TCK = 3,788MHz. ARM_STATE_AARCH64...
  • SWD for Time Profiling if no ETM Time Stamping is available
    Hi to you all, I'm using a LPC437 microcontroller (cortex M4) for a real-time application. I would like to measure the performance of a function I wrote in C, i.e. know how much time does the execution...
  • Porting to Arm 64-bit
    This white paper is an introduction to porting existing code to the A64 instruction set supported by Armv8-A processors like the Cortex-A53 and Cortex-A57 from Arm. It will also be useful for those...
  • Bus error while executing ARMv8 TLB instruction
    Hi, I am facing "Bus error on memory operation" while executing below instruction while invalidating and flushing the TLB. I am not able to understand what is the reason for "Bus error" as it is a TLB...
