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.!
