Hey,everyone
I am now using lwip. And I encountered one problem. I have to change the link speed. For several trials , I am sure I have to modify the source file under bsp. However , even if I changed the lwip source files , the liblwip4.o never changed,so what modification I have made makes no means.
Anyone can help me ? Thanks a lot.

For changing the link speed you have to work with EMAC interface i guess.
& also i guess it is nothing to do with source .c files you have to chage hardware for this and need to generate bit & bmm again. Then you should proceed with SDK devlopment.

Hello,
Thanks for your reply.
I know I have to change one bit of the register in the phy to set the link speed according to the datasheet. And I do this in the peripheral_test successfully. I set the PHY_REG0_SPD_100_MASK from 0x2000 to 0x0000, then the link speed changes to 10Mbps.
I want to do this in the lwip,But it doesnot work.
And you asked me to modify the hardware design , I don't kown how to do that. There are no options to do with the link speed in the hardware .
Waiting for your reply.
