Re: How to correctly run SMSC LAN91C111 Driver by interrupt


Thank you Gary,

I understood well.

Yes,right now I'm only running RedBoot Monitor.
Although I am aspiring soon to make eCos application run on my target.

At that time,I'll try again to implement interrupt.

Hi everyone,

Someone please help me.

I am trying to run SMSC LAN91C111 Ethernet Driver by interrupt
on own board.

I studied source if_lan91cxx.c and found next switching context

#ifndef CYGPKG_IO_ETH_DRIVERS_STAND_ALONE,

and concluded I must make CYGPKG_IO_ETH_DRIVERS_STAND_ALONE  '0'
in order to regisiter ISR etc.

I registered ISR into Vector Table.

When I Built,I confronted next errors.
/ecos-c/cygwin/home/LINK/inserter20070529-1_interrupt/untitled_install/lib/extras.o:
In function `do_exec':
/opt/ecos/ecos-2.0/packages/hal/sh/arch/v2_0/src/redboot_linux_exec.c:114:
undefined reference to `_eth_drv_dsr'
/opt/ecos/ecos-2.0/packages/hal/sh/arch/v2_0/src/redboot_linux_exec.c:83:
undefined reference to `_eth_drv_funs'

I infered they are concerned with eth_drv.c,and found eth_drv.c was
included in next three directotries in eCos source tree.
C:/cygwin/opt/ecos/ecos-2.0/packages/io\eth/v2_0/src/lwip/eth_drv.c
C:/cygwin/opt\ecos/ecos-2.0/packages/io\eth/v2_0/src/net/eth_drv.c
C:/cygwin/opt/ecos/ecos-2.0/packages/io\eth/v2_0/src/stand_alone/eth_drv.c

I am convinced that because I did not compile stand_alone,I confronted
the errors.

So,first I tried to include /net/eth_drv.c.
I found in order to include /net/eth_drv.c I must make CYGPKG_NET
available.
Then I was stuck in the mud.
I confronted Conflicting Errors continuously and couldn't even build
redboot.
I abandoned.

Then, I next tried to include /lwip/eth_drv.c.
In order to do that,I changed option parameter a bit.
I commented "active_if" line.

cdl_component CYGPKG_IO_ETH_DRIVERS_LWIP
##        active_if     CYGPKG_NET_LWIP

Then I could include /lwip/eth_drv.c,
but confronted next errors.
src/lwip/io_eth_eth_drv.o
/opt/ecos/ecos-2.0/packages/io/eth/v2_0/src/lwip/eth_drv.c
/opt/ecos/ecos-2.0/packages/io/eth/v2_0/src/lwip/eth_drv.c:70:29:
cyg/kernel/kapi.h: No such file or directory
/opt/ecos/ecos-2.0/packages/io/eth/v2_0/src/lwip/eth_drv.c:89: parse
error before "delivery"
/opt/ecos/ecos-2.0/packages/io/eth/v2_0/src/lwip/eth_drv.c:89: warning:
type defaults to `int' in declaration of `delivery'

I am in predicament.

Please enlighten me what is correct way to run SMSC LAN91C111 Ethernet
Driver by interrupt.

It appears you are trying to enable these things in RedBoot. RedBoot is a polled environment and has its own network stack, so neither of the actions described above are appropriate.

If you want to build an eCos application - not RedBoot - that uses your
target hardware, with networking using interrupts, you need an eCos
kernel configured for this purpose:

 % ecosconfig new <target> net
 % ecosconfig tree
 % make

A quick reference to the documentation (the Getting Started guide has
a section on how to build complete applications) would be a good starting
point:
