Ethernet not working with imx8mq-pico-pi-voicehat.dtb #24

Open Renegade85 opened 4 years ago

Renegade85 commented 4 years ago

Hello,

The ethernet connection works fine with the imx8mq-pico-pi.dtb file, however once I switch the dtb to imx8mq-pico-pi-voicehat.dtb , the ethernet connection stops running. I'm not using wifi - didn't install it during the yocto image build procedure.

I assume there is an issue with the dtb. Is there a fix for this issue or any directions what should be checked/fixed to get ethernet running even with the voicehat dtb?

Thank you very much for any kind of help and have a nice day, Renegade

@Renegade85

Sorry for the late reply. Thanks for your kind feedback.

I just test VoiceHat with test script and run iperf3 in the background. ("dtb" is imx8mq-pico-pi-voicehat.dtb) It works well. It seems i can't reproduce this issue on our side. I use the Yocto 2.5 release image downloaded from (ftp://ftp.technexion.net/demo_software/PICO/IMX8/pico-imx8mq/MFGTool/pico-imx8m_pico-pi-imx8m_yocto-2.5-qt5_QCA9377_hdmi_20190821.zip).

Does the VoiceHat expansion board on your side is powered by external 12V power adapter or baseboard?

I suggest to switch to use external 12V power adapter. There is a guide to set up jumper to switch to external power: Hardware Configuration of VoiceHat

BR,

Richard

Hi Richard,

No worries. :-)

Thank you very much for your response. I didn't download the image from ftp, I've built my own image based on your description onbranch:

Branch: https://github.com/TechNexion/edm-yocto-bsp/tree/sumo_4.14.y_GA Manifest file: imx-4.14.98-2.0.1_patch.xml

I faced issues while downloading the gpu-sdk, so I had to modify the local.conf file by adding:

export http_proxy export https_proxy

The image is without wifi (WIFI_FIRMWARE was not defined), thus I'm dependent on Ethernet only.

The VoiceHat is not connected to the board and I was able to establish internet connection via ethernet. However, after I've switched the dtb file (in u-boot), ethernet stops working - still no VoiceHat connected, only baseboard with SOM. As there is no VoiceHat connected in both cases, the board is powered via USB-C only.

My board revision is: baseboard: PICO-PI-8m Rev:A1 SOM: PICO-8M Rev:02

BR, Renegade
