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:

11:31:19.229980 ARP, Request who-has 10.0.0.100 tell 10.0.0.10, length 46

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.
