Can't find the code to initialize or configure phy in lwip demo

[aiweixin]

Hi,

    I have installed the SW32R45_TCPIP_STACK_1_0_1_D2202, and import lwip_s32r45 project.

    According to the description of the project, it can connect to PC and ping.

    But i can't find the code to initialize or configure phy in lwip demo.

    Why is there no code for phy? And, in device.c, the code is commented out.

    Additionally, it's the same in lwip_s32k148, which don't have device.c file even.

Hello,

Could you please specify the RTD version you have used and setup you have?

ENET driver is part of RTD.

Best regards,

Peter

Hi Peter,

    RTD version: SW32_RTD_4_4_3_0_0_D2112.

    Can you tell me that how do the lwip demo configure phy?

    Thank you!

Hi, 

which particular configuration do you need modify? The example uses internal GMAC module - you can modify for example Gmac_Ip_features.h header or other GMAC related headers:

Hi @jiri_kral & @petervlna ,

    Have you used this lwip_s32r45 demo project on S32R45 evb, and does it work normally?

    I debug lwip_s32r45 on S32R45 evb, and use "ping 192.168.0.200", but it failed.

    May I need to modify the code for software or pin for hardware based on the demo?

Best regards!

Hi,

The demo lwip_FreeRTOS_S32R45_M7 is working normally on S32R45 evb. Please make sure that your demo has executed after start_example() in main() as debug will stop at device_init().

Hi, 

this demo is working normally. Please check the example description.txt file. 

On the first message you wrote that the ping is working for you - or at least this is how I understand it. If it is not working - make sure that your PC machine uses IP address from the same subnet - 192.168.0.xxx
