SV32V234-EVB2 no network

pha1 — Wed, 10 Apr 2019 00:00:50 GMT

Hello all,

I just received the eval board S32V234-EVB2.

I follow the instruction in Auto_Linux_BSP_20.0_User_Manual.pdf to copy the image to a sd card.

u-boot and linux came up fine but the network, eth0 doesn't work.

Even under u-boot:

=> ping 10.0.0.10

ping 10.0.0.10

Loading SJA1105 firmware over SPI 0:0

Using FEC device

ARP Retry count exceeded; starting again

ping failed; host 10.0.0.10 is not alive

when linux boots up, there this error in the initialization of the SJA1105:

[ 2.105259] sja1105pqrs spi0.0: Loading SJA1105P SPI driver

[ 2.110579] sja1105pqrs spi0.0: Detected Device ID ae00030e ()

[ 2.116356] sja1105pqrs spi0.0: Detected device id is invalid: 00000000 . <<<<<

[ 2.160148] sja1105pqrs spi0.5: 2 switches initialized successfully!

tcpdump -i eth0 inside the eval board shows that the packets sent by the host got in, but the replies couldn't get out:

11:31:21.228704 ARP, Reply 10.0.0.100 is-at 00:1b:c3:12:34:22 (oui Unknown), length 28

the host didn't see the ARP replies.

Any suggestion to debug this is welcome.

Thank you.

Hi all,

I got the board to go on the network at the end but there's something I couldn't understand:

. for u-boot networking to work, I need to connect the ethernet port to the host; also I need to connect one of the automotive port to the host.

. the packets are going through the automotive port, but both ports have to be connected otherwise u-boot ping wouldn't work.

. now with the board connected as such (2 ports to the host), I can netboot the board.

Does anyone else observe the same behavior? I would like to make sure that my board doesn't have a problem, since the document doesn't mention that I need to connect 2 ports.

Any suggestion is well appreciated. Thank you.
