Other Parts Discussed in Thread: TPS65217
Tool/software: Linux
Issue:
Board does not get dhcp lease when running 100 MBit/s. Mii-registers reports link is up and auto neg is done. Wireshark shows no data.
When switching to 10 Mbit full duplex and autoneg on the board connectes and gets a dhcp lease after a while. Can verify with wireshark.
We also have one board from the production batch that actually goes up in 100 MBit/s and gets a dhcp lease but on that one 10 Mbit does not work.
We have tested to increase the time the PHY is in reset (normally around 29-33 ms) to 1 sec and still no improvement. This lead us to believe that there is a layout issue, is this something we can get help with if we send design-files?
Board:
We have implemented a am3358 together with a LAN8710AI PHY on a custom board (similar to the beaglebone black), connected using MII. We have an earlier version that works fine,
now we have a somewhat changed board version (powersupply added to driveboard) that somehow is not working.
Compiler and OS:
We use the Linux ti-4.14.40-rt29-gd5443cbd3b ḱernel and gcc with arago toolchain (arm-linux-gnueabihf). The OS is ubuntu 12.04 core with some stuff picked from the TI-sdk.
