libxud_u compilation problems

Post by GerhardNorkus »

Hi All,

Problems with sc_usb_device (1.0.1).

I downloaded, and there were a bunch of changes with the libxud library. Name changes weren't a problem, but when I compile, I always get the following message -

XUDManager.xc - undefined reference to usb_tile

usb_tile is defined in the .xn file. Previously, it had 'core' in front of it. Now it has 'tileref'. In any case, I cannot compile with the new module.

By the way. I am not using the standard method of importing modules. I simply copy the xud and usb directories into my own project. I then copy the libxud_u.a into the targets\lib directory of the xTIMEcomposer directory in c:\program files (x86)\XMOS directory in windows. I then add the following to my xcc flags: -lxud_u. This worked for libxud_s.

There was also a problem with two of the inlines in the xud.h file. XUD_SetReady_Out and XUD_SetReady_In get thrown as undefined inlines during the compile in this new version. Can anyone at XMOS look at this???

Which version of Tool are you using? You should use 12.2.0 for building XUD. You might not be able to build XUD module with 13 version of Tool.
