Hello everyone
I have designed a control system using MPC566, the design of hardware refer=
red to the MPC566EVB, and used Codewarrior and MPC500 Quick Start 4.0, incl=
uding the Configuration tool,to develop the software. There are many tasks =
running in PIT interrupts. The system has been used for a long time, it usu=
ally can run correctly, but it occasionally presents a phenomenon that the =
main task can run normally while the PIT interrupts can not execute, when t=
he system is powered up. Why? Have you found the phenomenon? Are there any =
questions on hardware? Please help me.
Thanks a lot!
