Hi,
Did anyone find this TX timeout issue on macb(gmac)? I observed this issue when i enable d-cache.
Log:
zynq-uboot> ping 10.10.70.101 gmac0: PHY present at 7 gmac0: link up, 1000Mbps full-duplex (lpa: 0x3800) Using gmac0 device gmac0: TX timeout gmac0: TX timeout ping failed; host 10.10.70.101 is not alive
Sure, this will happen, as the macb driver is not worked with d-cache enabled. If you want to let the macb work with d-cache enable, you should modify the driver.
BTW, if you want to enable d-cache, the MMU must be enabled.
Any help.!
-- Thanks, Jagan.
