SES 8.24 showing false “undeclared” errors on nRF5 SDK for Mesh v2.1.1 project

[Mr Sunshine]

I’m trying to debug an existing product by opening its old firmware project on a new PC. The project uses nRF5 SDK for Mesh v2.1.1, SoftDevice S132, and nRF52832.

I installed SEGGER Embedded Studio 8.24 and opened the project. Now the IDE shows errors that weren’t present before:

• Functions are marked as undeclared, even though “Go to Definition/Declaration” works.

• Standard types like uint16_t are underlined as unknown.

• #include headers show a green mark and say they aren’t used directly (not sure what this implies).

I haven’t changed the code. I’m not sure if:

• I misconfigured SES during installation,

• SES 8.24 behaves differently than my old version, or

• There’s an easy setting to fix this.

I want to fix the existing code on this setup rather than upgrade the SoftDevice or SDK, to save time debugging the current bug.

Has anyone seen this behavior when opening older nRF5 SDK Mesh projects on SES 8.24? How can I make SES correctly recognize all types, functions, and includes?

Hello,

I don't recall seeing this exact issue, but since SES v.8 is not compatible with this SDK due to changes in the standard libraries and toolchain anyway, I would recommend downgrading your SES version to version 5, which was the last version available at the time of this SDK release, and see if that fixes it.

Best regards,

Vidar

I went back to 4.10b which doesn't strait up give errors at first, but I now get the error message that the evaluation period is expired. And when applying the license key on Tools > License manager > Activate Embedded Studio I seem to be unable to press the 'Install License' button after pasting the license.

Did you install the license key for the new version? That used to cover the old versions as well

[Mr Sunshine]

no, I simply installed SES v8 and other versions to see if things were working. And uninstalled them if they showed errors.

Try installing the latest and activet the license and then open the old version as that should hopefully not complain anymore. You can't activate the licence with the old version due to SEGGER policy but the licence is valid for older versions as well (or used to be).
