Reconfigure Ethernet IP settings without power cycle

Try to reconfigure IP settings and software hangs at following code without power cycling:

    while (EthernetPHYRead(ETH_BASE,0) & 0x8000)
    {
    }

any solutions please? Need it to run for Ethernet based boot loader.

Thanks in advance!

Hi Ping,

This forum is for TI Ethernet PHYs( Physical Layer Transceivers).
Layer 2 and above are outside the scope of this forum. I will transfer this question to the appropriate group though.

Kind regards,
Ross

Hello Ping

Which MCU device are you using?

Stellaris ARM LM3s9997, it uses Static IP only, lwip based UDP protocol, need to configure different IP settings for both boot part and application part separately after entry.

Thanks!

Hello Ping

LM3S devices have been EOL-ed quite some time back and there is virtually no software support at this point. I would recommend using TM4C129x device instead.
