Hi all!
I'm trying to establish a Linux OS on a DM6467. I have the TMS320DM6467 EVM as a reference board. I flashed the u-boot and uImage properly on the EVM board and it works fine. When I tried to flash the Linux on our board the phy won't work. I asked the board designer and he said that the phy area is copied from the TI board schemes, so it should work the same.
When I command 'ip=off' in the boot environment the Linux rise properly, but doesn't ping. I used the NAND flashing because otherwise the kernel won't download the NFS, so I flashed the RAMDISK to the NAND. The EVM worked properly with the DHCP, but I wanted to do the same process in order to find the difference.
My questions are:
-
what is the phy driver? I'm using the LSI ET1011 phy as in the EVM but there isn't such en option in the kernel configurations. I added som kprints to find what driver it enters, but in the added log file you can see that it enters three different drivers.
-
Can it be a hardware fault? If so, how can I find it?
-
Before I flashed the NAND the uboot downloaded the kernel via Ethernet but the kernel couldn't download the NFS. What's the difference between the uboot end kernel, are they using different drivers?
Thanks a lot
Ely
Here is the log-file when I allow Ethernet:
