SDK 2.7.0 emWin not compiled with OS support?

[dariuskellerman]

Hello,

when compiling our Software against the latest SDK we're getting undefined references to OS-related emWin functions (undefined reference to `GUITASK_SetMaxTask').

This indicates that the provided library was compiled without OS support (see macro GUI_OS). Is this the case? And if so, is that change on purpose? We require OS support for our application.

Best regards,

Darius

Hi Darius,

Attached is the emWin v610 library for all toolchains which had enabled OS features. Please use the header files for emWin 610.

Have a great day,
Felipe

Hi Felipe,

thank you for your effort! In the meantime, we have integrated the new version. However, we noticed that the code size increased dramatically with this version. Could you check with the SDK team whether they had enabled optimizations for the compilation?

Thank you very much for your ongoing support!

Best regards,

Darius

Hi Darius,

Just to continue with the follow up. AE team have replicated your issue and reported to the corresponding SDK team. If there is any update I will let you know.

Thanks for bringing this to our attention.

Hello Darius,

I am sorry for my late reply.

Could you please provide the MCU you are working on? Also, please provide the example you are using to reproduce this issue. I'd like to replicate it on my side.

Best regards,

Felipe

Hello Felipe,

thank you for your reply.

The MCU we are using LPC54608. To get an example, just take any emWin example and call GUITASK_SetMaxTask in there.

Hi Darius,

You are correct, that function were not implemented in the MCUXpresso SDK. However, in the below thread you could find a way to integrate Amazon-FreeRTOS with emWin that you may find helpful.

Amazon-FreeRTOS with Emwin on LPC54628 

I hope this helps.

Best regards,

Hello Felipe,

thank you for the confirmation. Just out of curiosity, why was it removed?

And why does the delivered configuration file not reflect the actual configuration used for compiling the archive?

And when will it be fixed?

Integration is not a problem for us. It works with the old version, but we need the OS support! This is a severe regression.

Best regards,

Darius

Hi Darius,

Could you please let me know the old version of the SDK you are referring to that you were using with the OS support?

Hi Felipe,

we have been using SDK version 2.4.1 with OS support. I'm unsure whether it was contained in 2.6.0 as we have mostly skipped that version.

Hi Darius,

I have replicated your issue on my side and confirm that the SDK 2.7.0 was not compiled with OS support. The SDK 2.4.1 compiled correctly exactly as you mentioned. I have contacted applications team to report this, whenever I have any update I will let you know.

Best regards,

Felipe
