IMX6Q migration to IMX6D MAC driver issues

Hello Everybody!

We used 4-core IMX6Q for our project before, but now we need to change it to dual-core IMX6D. I directly used the device tree and kernel of IMX6Q before. Now the network card can receive data, but it cannot be sent out.Debugging found that ENET_EIR[TXF] interrupt has not been received in the sending process of network card, so it cannot be sent out!Do you know why?What changes do I need to make?Looking forward to your reply!

 

Thank you!

Hi lishun

 

for dual core recommended to use "maxcpus" kernel boot parameter,

maxcpus=n : n >= 0 limits the kernel to using 'n' processors.

also for new board/processor recommended to run ddr test
