dcache off doesn't help either. > Also try copying the network section from M28EVK, as M28EVK uses KSZ8021 > PHYs. I > also noticed the M28EVK resets the PHYs, so maybe you need to handle that ? On > M28EVK this is handled in board/denx/m28evk/m28evk.c By mistake, I forgot to add reset pin for the phy, so I am leaving the phy always enabled. I did try using M28EVK and MX28EVK board ports as well, but none worked so far. Do I have do anything special for the NC pins of IMX280? > Moreover, check if your CLKCTRL ENET settings are correct, that's also handled > in the same function as the PHY reset on M28EVK I think (or at least in the > same > section). That doesn't seem to be wrong. I see a clean 50MHZ clock on that pin. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
