MOD-ENC28J60 and Linux (Debian/GNU)

[vinifr]

I connected RST, the result is the same, but I saw it in the schematic is with the pull-up.

I tested in a13-olinuxino-wifi and a13-olinuxino-micro,also the same error.
script.fex for wifi: http://dl.dropbox.com/u/22273442/A13/script.fex

I connect this way:
ENC pins --- A13(connector UEXT)
SCK(1) --- SPI2_CLK (9)
MOSI(2) --- SPI2_MOSI (8 )
MISO(3) --- SPI2_MISO (7)
WOL(4) --- no connected
INT(5) --- PIN8 (PB4)
...
3V3(10) --- 3V3(1)
GND(9) --- GND(2)
RST(8 ) --- no connected
CS(7) --- SPI2_CS0(10)
CLKOUT(6) --- no connected

Hi vinifr,

the link down message is normal, is the initial state of the network..
Try to issue

How is your /etc/network/interfaces?

[lorenzo]

Hi,

I don't use the /etc/network/interfaces

If you issue

Code Select Expand

dhclient eth0
what is the result?

Did you also try with:

ifconfig eth0 down
Ifconfig eth0 192.168.1.150 up

Static ip also does not work. 
Could you post your logs of spi2, net and ifconfig messages?

Wow, something is wrong, I think it's my connections. When i put my finger on the chip it is very VERY hot!
how is yours?

[lorenzo]

Hi,

I don't have the enc28j60 module here with me, I will try tomorrow and let you know..
Spi and enc28j60 messages seem to be ok, I can't see any strange behaviour..

Your interface never switch to running mode? What the terminal shows when you issue dhclient command?
Which is the LED status on the ethernet interface?

[vinifr]

hi,

I found the problem, ENC28J50 not transmitting anything. I put my laptop as a router and it gets nothing.

I listen for packets via wireshark.

exactly, it does not change for running and only one LED lights.

[lorenzo]

Hi,

here is my dmesg, but read next post for solution (I hope) to your problem...

Hi vinifr,

I think I've found the error: in you script.fex file please change

Code Select Expand

csi_used = 1
to

Code Select Expand

csi_used = 0


Because CSI uses PE00 pin which conflicts with CS of SPI.

Cheers

[vinifr]

hi Lorenzo, you will not believe! besides that error csi_used, I made another terrible mistake!!!

I connected the enc IRQ pin on pin 8 (VGA_DIS) instead of the pin 13 (pin8), I mixed with one another. hahah

Is now functioning normally, with LED flashing and flag running:

thanks for help!

Are you using your version enc28j60_v2 or 3?

[lorenzo]

 , yeah sometimes it happens...
I'm using version 3... In version 2 there is a small error in one spi operation function, so it is better to use v3...

You can enjoy your wired network now! 

cheers

[vinifr]

Another thing, you realize that the chip gets very hot?

[lorenzo]

No, I didn't notice it (well, actually I've never checked that)... It's strange because it shouldn't have a high power consumption...

I'll try with a stress test and measure the temperature...

I've tried to send a proposal for a sun5i_enc28j60 driver:
https://groups.google.com/forum/?fromgroups=#!topic/linux-sunxi/iaxRsJorVh8

let's see what happens...

cheers

[vinifr]

I tested your enc28j60_v3, is as good as v2, I have not lost any package! Now we can consider that the ENC28J60 is functional for A13. Good luck with the patch.

The patch I would submit to spi_sunxi.c do not will work because there is not gpio_to_irq() in sun4i-gpio driver. I tested my patch with your enc28j60_v3 and i get "cpu tx data time out!"

How you solved tx data timeout?

[lorenzo]

The problem was in the spi clock frequency: when I reduced the frequency to 10MHz tx errors happen very very rarely.
I think the problem should be related to crosstalk: you shouldn't suffer of this issue because you have separate wires..

Have you experienced any tx errors? How was your network speed?
