Hello, I am testing a new design that have LPC2144 on it. I can load programs into RAM and run them but when trying to load in FLASH rowley tools fail. I tried a different board with LPC2148 and it worked fine. I can even load a program in RAM and this program writes to FLASH and my program works fine so IAP works fine. Has anyone used rowley tools with LPC2144? Is it possible that I have something wrong? Thanks, Gus Issa

Gus, We haven't seen an LPC2144--have you checked the part ID of the 2144? According to the loader sources it should be 402ff12. Can you also check your loader sources to ensure that the 2144 is supported in the version you have? -- Paul Curtis, Rowley Associates Ltd http://www.rowley.co.uk CrossWorks for MSP430, ARM, AVR and now MAXQ processors

This is the first chip where we had to set the JTAG divider and the "loader parameter"!!! We have never set these values before and everything worked great on LPC2103, LPC2114, LPC2134, LPC2138! It is still not rock solid as the other chips but I will look more into it.

Gus, The loader parameter is required to define the crystal frequency (in MHz, IIRC) so that the ISP flashing works. If you are using a CrossConnect you should not need to set the JTAG divider because the LPC series uses adaptive clocking (the RTCK signal), hence you should set the Adaptive Clocking property of the target interface to "Yes". In this case the CrossConnect interface will go as fast as the chip allows, assuming you have a CrossConnect. If you have a Wiggler, RTCK isn't supported and you do need the JTAG divider. -- Paul Curtis, Rowley Associates Ltd http://www.rowley.co.uk CrossWorks for MSP430, ARM, AVR and now MAXQ processors
