Difference between reset commands



Hi,

I'm using CCS with XDS100v2 / XDS560v2 (by BlackHawk) to debug code on AM335x chip.

  1. What is the difference between the following UI commands? What exactly is performed on each of these commands? Does the JTAG emulator pull nRESET_INOUT pin? PORz pin? Writes to the PRM_RSTCTRL register? Which reset is triggered - warm or cold?
    1. System reset
    2. CPU reset (SW)
    3. CPU reset (HW)
  2. What does GEL_Reset() function do?
  3. Does the CPU remain halted on first opcode just after the reset?

Best regards,
Vasili
