Failed Ethernet PHY?
« on: 2020-12-17, 23:49:20 »
Hi,

I have an RRC-1258 mkIIs v7 Control Side that seems to no longer be able to speak Ethernet.

Looking at the serial port, I see the following message when it boots:

==========================================
** 1258 Bootloader V1.14                **
** CPU type: 2387                       **
** 0114
** Booting application                  **
==========================================
** Press capital x for xmodem apploader **
==========================================

ENET_REF_CLK not running, skipping ethernet init.
Ethernet link timeout, activating Wi-Fi


On a working unit, I do not see the 'ENT_REF_CLK not running' message. Looking at the PHY package, it seems a bit on the tiny side to replace even with a rework station. Is it possible to get a replacement PCB? Any other suggestions as to what can be wrong?
