Hello all,

I'm working on a project with the Atmel AT89C51SND1C and I am trying to program it over USB using the FLIP application. Currently the application will connect to the chip and I am able to program it, however I'm not sure if I am doing it correctly. From my understanding, I should uncheck BLJB so that when ISP is high at bootup it will load my user application at address 0000h in user space. My problem is, whenever I set SBV to 00h to say to start from 0000h on reboot, the software always changes it back to F0h and the program never runs. Does anyone here have any suggestions about how to use FLIP and about my problem specifically?

Thanks a lot,
Mikael Nelson
