Hi, I'm working with the LPC1768 and I'm trying to use a reserved memory area to enumerate the address of some variabile that are stored on an external spi flash.
I've made with success the same thing on an LPC2376 (ARM7) but with the cortex I've got an error when I try to enter in debug mode:
"Error: Could not load file project.axf Debugger Aborted!"
I've tested that if I move my vars from the 'off-chip' area to the internal one everything is working.
In the target option I set:
ROM1: 0x80000000 SIZE: 0x100
And in the code I use this code:
const uint32_t ee_test __attribute__((at(0x80000000)));
When I start debugging session I got on the console:
Load "L:\\PROGETTI\\project.AXF"
Full Chip Erase Done.
No Algorithm found for: 80000000H - 8000001FH
Partial Programming Done (areas with no algorithms skipped!)
Application running ...
But then keil gives me an error and abort the debug session.
Maybe there is another way to map some variabile in off-chip rom sections?
Thanks to all!
Hi guy's I've solved my problem. As I discover it was related to the debug session I create a fake alghoritm to talk with the external eeprom (specifying the areas).
I've cloned another SPI_EEPROM flash algorithm from the keil dir and left all the function empty (leave just the 'return 0' instruction), copied it in the algorithm folder and added to my project debug settings.
Follow the Keil UserManual instruction at uLINK2 "Setup Flash Programming" page.
Now it's working fine.
BR,
Samuele.
