Critikel failer with 5270

[11011-san]

I was developing some software for a NetBurner 5270. I have been able to insert several versions of the software(samples and my own code) both throu the ethernet or the serial if ethernet fails. But this time the problem seemes more severe and i'm at a loss. I placed the application on the 5270 throw ethernet and got no respones so i did the usual, took out the serial to see that is hapening but i got no response even when pressing reset i get nothing on UART0 and i even tried UART1 but nothing. The only thing i have ever been able to get is 2 random characters when connecting the power but not when presing the reset button. i'v tryed different computers but i get the same result. is it possible to fix this or make a factory reset or something? it will be much apreciated.

There is a chance that the monitor lives and is squeaking at a different baud rate than you are monitoring at. You would need to connect a scope to the port 1 Tx and the port 2 Tx lines after reset and look for data. If there is only silence you will need to have NB reflash the monitor.

......................
If one is developing code that writes to the FLASH it is always smart to have two modules, that way one can be at NB getting reflashed and you can keep working.

Alternately, one can purchase a USB Coldfire BDM pod from P&E and reflash the monitor each time your code does the bad thing. I have killed many a monitor while developing FLASH programming code

BTW The MAC address must be re-entered after re-flashing the monitor
