Part Number: MSP430F5310

Tool/software: TI C/C++ Compiler

I am getting the following error:

#10229-D output section ".data" refers to load symbol "_nop" and hence cannot be compressed; compression "lzss" is ignored

I found this link where George hints at the underpinnings of the issue:

https://e2e.ti.com/support/development_tools/compiler/f/343/t/293073

As he stated in that post, it's no big deal if you code fits into the flash.

However, there is the rub; My code does not fit into flash. I would like to get the compression working to see if my code will fit.

Is there any way to figure out what is causing this?

Also, I am linking in an array that is 0x2000 bytes. It does not need to be accessed in real-time. It is a backup bootloader image if it needs to be programmed. So, at application run-time, it is dead-weight. It would be great if the lzss compression could be applied to this array at compile\link. I would need access to the decompression routine. Also, can the decompression operation on sections of the blob, say 1K at a time as there is not enough RAM left for the whole image.

This older forum thread lays out all of the details. Fair warning: It is a long read, and quite detailed. That thread discusses the problem with regard to the TI ARM compiler tools. But the issue is the same for all TI compiler tools, including MSP430. To apply the knowledge in that thread to your particular case, I tried and failed to reproduce your problem. The best way for me to reproduce your problem is for you to submit your CCS project. Please see this post on how to do that. If you are not willing to do that, then at least attach the linker command file(s) to your next post, and show all the build options exactly as the linker sees them. I might be able to reproduce it with that.

Start with the section of the MSP430 assembly tools manual titled Linker-Generated Copy Tables. Pay particular attention to the sub-section titled Compression.

I don't think so. The granularity of control is a single output section. A single array cannot somehow span across multiple output sections.

Thanks and regards,

Here's the TL;DR for that thread:

the real problem is that in the linker command file, the section ".cinit" is being placed inside a group with sections that it refers to. This is problematic. .cinit should not be placed in a group with any section that will be initialized at startup.

In your linker command file, make sure that .cinit is not in any GROUP, and tell us if you still have this problem.

Hi George,

Thanks for all the info. It will take a look at it.

I will look into sending you the entire CCS project. In the mean time, I have attached the linker command file to this post. The forum does not allow upload of .cmd files so I have changed the extension to .txt.

You are correct, I had the .const inside a group. I took it out of the group but I still get the same error. Both .cmd files are attached to this post.
