I've written a stupid main, and liked with target.ld. My question is, now do i have to init on my own the device?(pll, flashor do i have to call some sort of function inside the library?
Take a look at the test programs. They are good examples of how you write eCos programs.
Unlucky i cant test these programs, the only way i have to test programs is load them in flash with samba and cross my fingers. I take a look, but i still can't figure who init my board (i guess hal_platform_setup.h)
ecosconfig new at91sam7xek minimal ecosconfig tree make -s tests tree install/tests
i've already tried to call my lowlevel_init function(already tested) but nothing happen(i try to light a led), any hints?
Start with one of the test programs. Maybe tmbasic. Since this is a known good program it allows you to concentrate on everything else. Once this runs you then know your development environment works, your JTAG progammer works, etc.
Then you can start debugging your own programs. Humm, leds. Are you using the GPIO macros in var_io.h? Have you configured the pin to be an output? I think one of the AT91SAM7 boards has the logic inverted. ie 0 causes the LED to be on, 0 causes it to be off.
yes, mith macros, but nothin happen. Thanks for your support Andrea
