I would like to add the ISP code from NXP AN10337 to my project for an LPC925, however when I add it I get a whole lot of errors. Without listing them all, is there anything simple that I should set in my IDE to make this asm file get included?

In the assembly file, there is no header included for the SFRs.
To define the standard 8051 SFRs, check the option "Define Symbols for ..." in: "Options|Project|MA51|Source".

This worked perfectly - thankyou.

No the next question. is there a standard Raisonance startup.a51 for the LPC9xx series, I have tried the Keil one, and although it compiles in OK, it won't boot.

Should this be under a new thread?

Thanks

To all others that are having issues with the programming of the UCFG in the LPC's

simply declare a variable at the top of your main.c file along the lines of the following

at 0xFFF0 code char regis = 0x93;

then you don't need a startup file (unless you want to do other special stuff to it)

Thanks to the Acqura.com help files for the emulator for this insight.
