Hello everbody.

   This is my first topic. I have purchased USING THE FREERTOS REAL TIME KERNEL - A PRACTICAL GUIDE USING LPC1769. I have done every step in the book, but I am not able of compiling any example. I always get the same error in the LPCXpresso compiler:

“cannot find -lCMSISv1p30_LPC17xx”

   This file is loaded in the workspace by default when I import all the example files. All seems to be ok, but the error is the same with all the examples. Somebody could help me?

                    Thank you!!!

Which version of LPCXpresso are you using? I found out a couple of days ago that the projects won’t work with LPCXpresso 7 (the new version). If you are using version 7 I can provide some links that explain the problem while I work on updating the projects.

I use FreeRTOS with version 7.1 (just downloaded 7.2) but since I just
copy/overwrite files into a known working job I don’t have any problems
with it.

LPCXpresso has also gotten somewhat better about opening jobs from older
versions, not quite as much stuff to manually fix.

Take a look at the following, it looks like the fix is quite simple:
