ARM7_LPC2106_GCC Example working?

Posted by Harald Kubota on February 23, 2009
Hi,

When I tried to make an LPC2103 work with the LPC2106 gcc FreeRTOS demo work, I thought "That's gonna be easy". Well, it is not.

I am at my wits end. I know the board works. The compiler is good, the linker too, I modified the obvious suspects (crystal frequency change to 19.66MHz from 14.xMHz, change of multiplier/divider for the PLL accordingly, change of the linker file to reflect the smaller flash and RAM of the LPC2103 vs. LPC2106, I use ARM only).

Yet I don't get a single blinking LED out of it.
Same when using an LPC2148 (similar configuration changes).
Unfortunately I do not have the Olimex 2106 board.

Is that ARM7_LPC2106_GCC demo working for anyone?

Harald

Try removing all the tasks except the flash task. also you will need to verify that the pins are configured right. eg pin select block and dir. I would suspect the RAM difference is the main problem.
