Hello, following problem at the C8051F352: After successful compilation and transfer of the program to the flash the program starts either not or processes only the first instruction in the MAIN function. I take a Codeline from the program or a nonlocal quantitative characteristic comments, the program without problems runs. The memory is not, however, excessively full yet: ########################################## Program Size: data=90.1 xdata=24 code=6703 LINK/LOCATE RUN COMPLETE. 0 WARNING(S), 0 ERROR(S)#################################### Where does the problem lie? To come experiments already some time behind that, however in vain. You can give me a reference, why such responses occur. I already executed an update onto the most current release, did not bring, however, also any remedy . Best thanks for your aid.r
