I can’t even seem to set this demo loaded, keep getting “loader verify failed”. I’m using Crossstudio 1.6 with a IAR jlink jtag (Seggar I think)and a brand new AT91SAM7X256-EK. I’ve used other programs written with crossworks and they all load & debug well using their CTL. I’m sure its a simple setup issue, anyone point me in the right direction please.
I have only used a CrossConnect on the SAM7 so cannot answer directly. Have you compared the j-link settings between the project that does work and the project that does not?
1/ Open a project that you can get working on the SAM7 using a j-link.
2/ Select Targets from the Target menu in CrossStudio.
3/ Right click on the Segger j-link entry in the targets pain the opens, then select properties from the pop up menu.
4/ Note down the settings that are displayed.
5/ Open up the lwIP demo and do the same to check that the settings are the same in this project also.
Failing that, try the Rowley tech support. I have found them to resolve problems quickly.
I have noticed with the newer Sam7X’s that the Rowley tools do report a verify failure after programming. If you do a memory compare, however, everything seems to be OK.
