LPC4337 reset error

[luiswalther-aco]

Hello, i am Using a LPC4337 with ethernet but i have a problem after reset, when i made a POR (power on Reset) the Microcontrolller works as expected, and the ethernet works fine, but when i made a reset from reset pin or a software reset from the core_reset register than the controller cannot initialize the ethernet, i think that maybe is a bug because i am using a 25MHz external crystal ? because on the LPCxpresso board the Reset from pin dont have any issue.

Thanks

Hi Luis Walther-Acosta,

Thank you for your interest in NXP Semiconductor products and 

for the opportunity to serve you.

1. Firstly, I'd like to recommend you check the crystal oscillator circuit by referring to the 13.2 Crystal oscillator section in the attachment.

2. Next, whether you describe the issue in details, as I'm still not very clear with it.

I'm looking forward to your reply.

Hi jeremyzhou

Thanks for the answer, is solved, I verified  the problem and I was  not initializing my Ethernet PHY correctly, the clock on the LPC4337 are correct, also it was not a problem of the Microcontroller........
