Hi all
When i included the struct as is the my board with the MPC8548 ver1 cpu worked correctly but the board with ver2 CPU does not work. A would appeciate any help
In what way does it "not work"? the cpu version shouldn't affect PHY recognition. Is the board different? Does it have different PHYs?
On both boards (CPU v1 and CPU v2 ) the phys are detected as the Vitesse VSC821, but someware in the the "miiphy_register" function in miiphyutil.c thinkgs go wrong on the board with the v2 CPU. The first symptom was the mesage:
miiphy_register: non unique device name ""
on deeper investigation i found that the phy names were jumbled garbage, as the lines below show: the NET name should reed Tsec0.
PHY is Vitesse VSC8211 (fc4b1) miiphy_register: added '��m@��v|�� ��n', read=0x1ffb2e7c, write=0x1ffb2e14
after a bit more digging I now thing the problem is in the Memory manager of the CPU but i do not know how to go about finding the problem. My first step is to look at the DDR setup then try to understand the differences between the v1 and v2 CPUs
If you have any links or help i would greatly appreciate it.
thanks hedrik
