I have used the LPC1768 and LPC1788 with Ethernet and didn't have any
difficulties (using the LPC1788 on the IAR board).
Check carefully that the ENET pins are all configured correctly (see below for
list in RMII mode) and check that all clocks are set up correctly (clocking is a
bit different):
Finally, if you are running the CPU faster than 100MHz makes sure that you have
the power boost (in the new PBOOST register) set otherwise there may be some
strange behaviour.

Hi all,
I have developed ethernet driver for LPC1768 using CMSIS lpc17xx_emac driver.
And I have applied this driver for LPC1788 using CMSIS lpc177x_8x_emac driver
too.
But while 1788 CMSIS EMAC Driver setting the Ethernet Physical Mode (calling
EMAC_SetPHYMode), its take long time, like as 20 seconds.
1768 is working fine.
I cant understand the problem.
