Exception table sections and plain sections cannot be mixed

[Christopher Hunt]

Hi there,

I'm attempting to link in a static library archive to my nRF52840 targeted project and receive the following error:

Exception table sections and plain sections cannot be mixed

I've not been able to find a description of this error. I suspect that it is something to do with the way I've built the static library archive, which is written in Rust and therefore generated outside of the Segger IDE. I'm also posting to the Rust Embedded forum and the Segger IDE forum but thought I'd better ask here also, in case it is something nRF specific.

Thanks for any help.

Seems as though the problem was somehow related to Segger. I moved to the gcc toolchain and all appears well.

Hi,

I am happy to hear that you found a working solution.

In case you want to dig into why your library doesn't link with your project in SES, I suggest having a look at the memory map file and section placement file. Those are the files telling SES about memory usage and where to put the different segments of the program. The error message indicates that there are section placement constraints that cannot be met with the current placement files.

Thanks. I suspected that it might be an issue around memory placement, although that message the linker provides isn't exactly clear. That said, I'm perplexed as to why the `.../pca10056/blank/armgcc/blinky_gcc_nrf52.ld` works for Blinky, but the Segger generated approach doesn't.
