Why is "speed selection = 10 Mbps" when both sides support 100Mb? Is uboot decoding this register correctly?
uboot> mii dump 0 0 0. (1000) -- PHY control register -- (8000:0000) 0.15 = 0 reset (4000:0000) 0.14 = 0 loopback (2040:0000) 0. 6,13 = b00 speed selection = 10 Mbps
This b00 here is confusing. b is a valid hex character, I thought this was reporting the register value as 0xb00. Instead it appears to be trying to indicate that the two bits are binary?
looks that way. it's showing bit6 and bit13.
It's in the source that way. It just confused me when trying to figure out what is wrong with the new PHY we're having hardware trouble with.
enable debugging in the PHY driver then ... sometimes it outputs something that is only obvious when you see explicit statements as to what it's doing -mike
