WDT behavior mystery - LPC1788

Hello,

I am dealing with a puzzeling situation: working with an embedded artists LPC1788 board, I have a program that enables the WDT but fails to restart after it resets the system (it crashes hard, disconnecting the debugger). But if I then power cycle or use the reset button - the program starts up correctly! I see no difference between WDT reset and external reset in the user manual.
I have to say that it looks as if it is related to memory (?); If I do not start FreeRTOS scheduler the program will not crash, but it is still hard to explain! Any ideas?

  • In other words - the LPC1788 suffers from the same issue, and the EA evaluation board for LPC1788 cannot recover from watchdog resets if the network interface is used. I discusses the situation with one of the hardware people; we are going to use another PHY that requires a much shorter reset pulse!
