Turn off Auto-negotiation and run on fixed speed.

[ranjay_shandilya]

Hi,

I'm using i.MXRT1050 EVKB and trying to run sdk example (lwip_dhcp_bm) for supporting ethernet.

I want to turn off Auto-negotiation and run on fixed speed. Is it possible?

Is there any auto negotiation flag which can be set for this in the code?

Thanks

Hi,
Thanks for your reply.
Actually, in the SDK library, the PHY driver can support configuring speed manually when turning off Auto-negotiation.

Have a great day,

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1) I want to turn off Auto-negotiation and run on a fixed speed. Is it possible?
-- Yes.
2) Is there any auto-negotiation flag that can be set for this in the code?
-- Yes, you can set the phyConfig.autoNeg to false to disable the auto-negotiation function.

@jeremyzhou Thanks for the reply. After setting this to false, Ho do I set the fixed speed (say I wanna run at 10 Mbs).
