Hi -- Keil supplies uV2 and C51 for the philips 9xx (P89LPC9XX) 8051 derrivative. When you make a project you are asked if you want uV2 to supply an assembler file: START900.A51 . One of the tasks this program does is to define the start of code and also to define the start of the stack and initialize the stack pointer (SP). It also sets configuration bits for things such as the speed of the crystal for the 9XX devices. I see no mention of START900 in your compiler specific application notes and user manual. Does salvo define the start of code and set the stack at the right location and set configuation bits (answer to config bits is no)?
