I have a PK51 Keil dev kit with C6.20 and MCB51, with a Atmel W&uC (Temic ) T87C52X2 i'have created an application that use serial internal with Timer 1 and use RTX Tiny to manage 4 tasks, if I execute program with Keil Mon51 v. 2.9 & 3.0 is ok , otherwise i write an EEPROM with HEX file created by Keil and switch on Ev.Board the program is not running ... using leds i see that doesn't execute the first istruction. Thanks Franz
yes.... I do another program without RTX Tiny and the program on EPROM is running ok. In the code I use 2 functions in 2 tasks so warning message appear : "MULTIPLE CALL TO SEGMENT" and program not running with EPROM but running with Mon51.
