EB Tresos: Multiple definitions of "DriverConfig"

Hi,

I'm using BMS SDK Gen2 with EB Tresos. I want to pass to the Bjb_D1xx driver and to the Bcc_774a driver a config struct during initialization, thus I need to select "Config Variant: VariantPostBuild" in both modules.

However, each driver gets generated with a DriverConfig variable that gets included, leading to compilation errors:

How can I configure both drivers to allow post-build parameterisation without leading to compilation errors?

Re: EB Tresos: Multiple definitions of "DriverConfig"

Hello @PhilippH,

As I mentioned privately, the case was under review by the development team.

They have provided the following answer:

"To fix the issue, the customer can prefix these variables with the module name (e.g. Bcc_774a_ and Bjb_D1xx_) in the generated code. Note that this change shall only be used for testing purposes and shall not be used in production."

Best regards,

Daniel
