Hello to all. I'm trying to port linux 2.2.14 on MPC860T and busybox as initrd. The eth0 device is working so i have network capability. Now i'm trying to get the FEC device working. In the booting process the FEC is initialized ok (or so i belive), IRQ(FEC)=3. The problem is : when i use the FEC as my network device there is no interrupts from this device (unlike when i use the eth0 device as my net device). The LINK led and the TX led are on constantly when i connect the FEC to a 100TXBase switch. I have not seen any initializetion of the BCSR4 so i initialize it with the value that ppcboot uses , so the ENABLE led is on too. The device isn't working even when i use ppcboot (i configured ppcboot to use it).
1. Why there is no initializetion of BCSR4 in the original code? 2. If BCSR4 must be initialized , what is the correct value? 3. Is any one have a code that succeeded getting FEC device to work? 4. IVEC(ILEVEL) bits of the FEC are initialized but when i read the value of this register i get 0x00000000 . Is this the problem ? and if so how can i fix it ? thank you for your help oshri. o_yahav at netvision.net.il ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
