Subject: [ECOS] porting eCos / Network Stack
Date: Thu, 27 Nov 2003 09:59:00 -0000 [thread overview]
Message-ID: <000001c3b4cd$037d6230$408010ac@leo> (raw)
Dear eCos community,
our problem: how to get running eCos + network stack on Atmel
At91rm9200 controller?
what we have achieved so far:
1 porting eCos to the Atmel At91rm9200 (=ARM922T), runs with configtools
default.ecc and redboot.ecc
2 adding ethernet driver for onboard EMAC of the At91rm9200
3 redboot running over ethernet (polled)
4 using configtools net.ecc we created eCos + network stack. When we
start this up with the 'twothreads.c' example,
we get the following debug print:
Init device '/dev/ttydiag'
Init tty channel: 20035a2c
Init device '/dev/haldiag'
HAL/diag SERIAL init
Network stack using 65536 bytes for misc space
65536 bytes for mbufs
131072 bytes for mbuf clusters
[cyg_net_init] Init: mbinit(0x00000000)
[cyg_net_init] Init: cyg_net_init_devs(0x00000000)
Init device 'emac_eth0'
[cyg_net_init] Init: loopattach(0x00000000)
[cyg_net_init] Init: ifinit(0x00000000)
IFP: 0x20034e34, next: 0x20083ba0
IFP: 0x20083ba0, next: 0x00000000
[cyg_net_init] Init: domaininit(0x00000000)
[cyg_net_init] Init: cyg_net_add_domain(0x20035744)
New domain internet at 0x00000000
[cyg_net_init] Init: cyg_net_add_domain(0x20035230)
New domain route at 0x00000000
[cyg_net_init] Init: cyg_route_init(0x00000000)
[cyg_net_init] Done
...... now the twothreads.c example is running properly but the network
thread is sleeping ....
P R O B L E M: the eth_drv_start() function is never called. Why?
That function will enable the network interrupts of the EMAC, so it is
urgently needed to be called somewhen.
