My company is using Philips 8031 chip. The new batch of chips we received, every one of them keeps reseting itself when when it come accross the PRINTF statement !!! The c-code works fine with the old 8031 chip !! Does anybody in this forum experience such problem? The PRINTF statement we are using is to send out a stream of characters to the RS232 port. It is a SOFTWARE routine, we are not used the built-in UART, could this be the problem? however, I was very confused why the old chip works !!! Thanks in advance, any helps or suggestions are veru appreciated.
Here's another idea. Could this be a power-supply problem? Jon
