NRF_SECTION_SET_DEF usage into crossworks IDE with GCC

[ThierryC]

Hello,

I have a running environment on Crossworks IDE, nRF52832, S132 based on SDK 12.3.

I try to migrate it on SDK 15.2, to use nRF52840 and S140.

After I included all the sources files on my project, I got these errors:

undefined reference to '__start_sdh_state_observers'

undefined reference to '__stop_sdh_state_observers'

And similar errors, all related to new NRF_SECTION_SET_DEF

Looking at the SDK documentation : https://www.nordicsemi.com/DocLib/Content/SDK_Doc/nRF5_SDK/v15-2-0/lib_section_iter?1179#lib_section_iter_usage_module_usage

Apparently I must change something on a "linker script", but I cannot figure out where on Crossworks IDE environment.

Someone has a hint of what to do ?

We have very little experience working on CrossWorks IDE, just wanted to know why you chose that IDE, when there were SES which is officially supported in our solutions.

So looking more on this subject I found:

• Crossworks IDE currently support only SDK up to 12.2 (http://www.rowleydownload.co.uk/arm/packages/index.htm?http://www.rowleydownload.co.uk/arm/packages/nRF51.htm)
• S132 is supported for nRF52840 only for "demo purpose". If I correctly read this (https://www.nordicsemi.com/DocLib/Content/Comp_Matrix/nRF52840/latest/COMP/nrf52840/nRF52840_ic_rev_sdk_sd_comp_matrix), we MUST use SDK 15.x for a nRF52840 product. Correct ?

Both of these seems to says that we cannot build a product using nRF52840 with Crossworks IDE.

From these I have options:

1. Try to make SDK 15 working "the best as possible" on Crossworks by manually changing some file of the SDK.
2. Use SDK 12.3 and SD140 (with nRF52840). What's the risk ?
3. Migrate ALL my project to SES (or Keil ?). But this will take some time.

None of these solutions are without risk, and 'm not sure which one to choose. What do you suggest ? Other ideas ?

 Please do not do this. SDK12.3 is maintained for nRF51 devices and all fixes and updates on nRF52 devices are not going into SDK12.X releases. The risk of failures is very high here.

I would recommend you this. But before doing that, please ask Rowley's guys to confirm if they have any updates on supporting nRF52840 with SDK14.x and above. If not, then I think porting your project to SES is what I would recommend. We at Tech Support use Keil/SES/GCC/IAR a lot and could help you even from basic to advanced configuration.
