[ptxdist] Ethernet does not work in EFM32 Giant Gecko

[ptxdist] Ethernet does not work in EFM32 Giant Gecko

[Jinyun Ye]

[-- Attachment #1.1: Type: text/plain, Size: 1294 bytes --]

I'm trying to enable network on my EFM32 Giant Gecko (FPGA version
0v1p1b148), but failed. Here is what I did:

1. Downgraded to board firmware 0v9p9b909
2. Enabled ping and route in busybox
3. Built, burnt and boot uclinux successfully
4. ping local eth0 but doesn't work:

/ # /sbin/ifconfig
eth0      Link encap:Ethernet  HWaddr D6:C5:6F:EC:7B:F1
          inet addr:192.168.0.100  Bcast:192.168.0.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
          Interrupt:4

          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
          Interrupt:4

Please share me some hint, if anyone have succeeded before.

Thanks,
Joey

not sure this is necessary. Anyhow, this is the version I do use, too.

I assume you're using the BSP from
http://git-public.pengutronix.de/?p=OSELAS.BSP-EnergyMicro-Gecko.git?

Full kernel log and the content of /proc/interrupts between all steps
would be interesting.

Why do you ping your own ip address?

Re: [ptxdist] Ethernet does not work in EFM32 Giant Gecko

[Uwe Kleine-König]

Hello Joey,

I retested ethernet on my board and it doesn't work there either.
Probably the problem is the irq controller implemented in the board's
FPGA being buggy. I already talked to my contact at Energy Micro about
that and they are aware of the problem, just didn't find the time yet to
address it. I just pinged the problem. (In the hope this ping works
better than the efm32's :-)

The workaround is to connect the phy's irq line to a gpio of the Gecko.
Then the FPGA is out of the loop. That's how we at Pengutronix did it
for our Embedded World demo back then.

Best regards
Uwe
