loader.xc compiling error: undeclared identifer `tile'

[philwick]

Hello all,

I’m trying to apply the AN00109 (multiple firmware booting) in a project using an XS1-U16A-128. I have modified the loader.xc source provided with the AN and tries to compile it using the same command as in the AN.

Code: Select all

xcc -c <path to>/loader.xc -o <path to>/loader.o

The compiler throws an error at the very beginning of the loader.xc code:

Code: Select all

#include <xs1.h>
on tile[0] : in port p_button = XS1_PORT_16B; 

The compiler reports the error:

Code: Select all

error: use of undeclared identifer `tile'

If I remove the tile specification, then the loader.xc compiles, but I get an error at some point when running flash that states that the port p_button is not assigned to a tile.

Code: Select all

loader/loader.o -lxcc -o s2l-n0-92ba50e6
xmap: Error: Port p_button is not placed on a specific tile.

What’s wrong with my loader.xc ?

Thanks

Replying to myself....

The compiler command that works is the following:

Code: Select all

xcc -c <path to>/loader.xc -o <path to>/loader.o -target=XS1-U16A-128-FB217-C10

The “-target” options specifies the xmos chip used.

Thanks for sharing the solution!

Hi, curious can the button port defined in the loader also be defined in the image to be loaded? In other words, can a button be used to revert to factory on boot and also be used for a different purpose once the appropriate image is loaded?
