Hi
I am just trying out version 5.2.2 (LPC1768). After importing an existing FreeRTOS project I get the above error on linking cr_startup_lpc17.c.
Even just creating a new 'FreeRTOS' project for LPC1768 then building gives the same error. Creating a non-FreeRTOS project pulls in a different version of cr_startup_lpc17.c which links fine.
The existing project (and creating a new project from wizard) work fine on 5.1.2.
It seems that the .ld file doesn't create '_data' just 'data' sections.
Any ideas so I can use the new version ?
Thanks.

Hi,

You have found a bug in the 5.2.2 release. The problem is a typing error in the managed linker script mechanism. We will fix this asap, but in the meantime we have a workaround.

1. Please read this FAQ on using linker script templates:
http://support.code-red-tech.com/CodeRedWiki/EnhancedManagedLinkScripts#template
and follow the instructions for using a template
2. Instead of using the link_template.ld mentioned in the FAQ, please use the version attached to this post.

Apologies for the inconvenience; we will release a fixed version soon.

I'm having the same problem with LPCXpresso 5.2.4 and a propietary library. Resolves the include fine, but when compiling I get error in every function from that library.

I suggest that you create a new thread and post some actual details of your problem. Make sure you include your build log.
