A building project problem.

[john71]

I created a project in MCUXpresso IDE v11.4.1_6260. Then I exported a SDK for i.MX RT1160 MCU (SDK_2_10_0_MIMXRT1166xxxxx.zip).

Then I successfully build an empty project.

Now I try to work with LWIP library – Ethernet.c

But while building I get some errors

D:\Workspace_MCUXpresso_11.4\MIMXRT1166_EVK_Project\lwip\port/enet_ethernetif.h:89:5: error: unknown type name 'phy_handle_t'

phy_handle_t is defined in fsl_phy.h however I see

unknown type name 'phy_handle_t' I see in lwip/port/enet_ethernetif.h

What can be wrong?

Hi @john71 ,

  Please run the SDK project directly:

SDK_2_10_0_MIMXRT1160-EVK\boards\evkmimxrt1160\lwip_examples

The SDK project also has your mentioned phy_handle_t, so please check your path, you need to add phy path.

Best Regards,

Kerry

[john71]

I have it included - /${ProjName}/phy.

I ported an example project from SDK - evkmimxrt1160_lwip_httpssrv_mbedTLS_bm_cm4.

Checked - all paths like /${ProjName}/... are present  

When I build it I get some errors also related to LWIP

 It's not my first project in MCUXpresso. I've build some projects in the past

 In MKV58F1M0xxx24 I also have LWIP and it compiles OK.

Hi @john71 

Please use the cm7 project instead of the CM4, as to the RT1160, CM7 is the master core.

evkmimxrt1160_lwip_httpssrv_mbedTLS_bm_cm7.

But, even you use the evkmimxrt1160_lwip_httpssrv_mbedTLS_bm_cm4, you should still can build it:

This is my build result:

Do you want to create a new project?

If yes, I recommend you based on evkmimxrt1160_lwip_httpssrv_mbedTLS_bm_cm7 directly, if you build this without issues, then you can copy past, or rename the project to your own project name, then based on it.

Best Regards,

Kerry

[john71 · Accepted solution]

Well..I ported SDK_2_9_0 instead of SDK_2_10_0 and now it's OK.

Hi @john71 

Thanks for your updated information.

If your issue is solved, please help to mark the correct answer, just to close this case, thanks.

Any new issues, welcome to create the new case.

Best Regards,

Kerry

Hi @john71 ,

  Do you also add the path in the MCUXPresso project? Seems you lack the path.

 BTW, do you test the SDK code project directly for the lwip, that SDK project works OK, you can refer to the SDK project directly.

Wish it helps you!

Best Regards,

Kerry

Hi Kerry

How do I add the path? In Settings->Includes I see all the paths to libraries.

If I exclude my code from the project I get some errors in LWIP library any way

../lwip/port/enet_ethernetif.c:119:9: error: too few arguments to function 'PHY_GetLinkSpeedDuplex'

../lwip/port/enet_ethernetif.h:89:5: error: unknown type name 'phy_handle_t'

../lwip/port/enet_ethernetif_kinetis.c:386:43: error: request for member 'mdioHandle' in something not a structure or union
