Dear all, i work with the Oregano systems 8051 IP core and would like to bulid a program with the RTX Tiny. Task 0 of a program runs, but it just doesn't switch to another task whereas it does when i select another target device. After that, i realized that this controller is not in the list of supported devices (http://www.keil.com/rtx51/chips.asp). The questions now are: - is there a way to use the RTX Tiny with this controller anyway? - is there another os that can be used with this device? ..a free tiny version would be nice... Thanks for your help and best regards, Tobias
