- Subject: RE: [ECOS] Ethernet & serial problem
I have checked some thing that might interfere with each other:
* TxBD and RxBD -> They are corretly setup both for serial and ethernet. Serial 2800 and 2820, eth 2840 and 2850.
* In my main i do init_all_network and then a while(1). The ethernet ISR are then called when running quite regulary. However, the board cannot be reach with a ping.
* The serial driver are called first and it makes me woundering my the ethernet driver doesnt work since i should re-set some values it they were set wrongly be the serial driver.
What else should i check?
