LAN8720 LINUX DRIVER

If you do not apply the configuration pulling resistors on your board, then the internal pull-ups on the LAN apply and the Waveshare board will default as follows: This configured the PHY for full auto-negotiation. Resistors R11 R12 R14 have different value if we compare it to Microchips schematic. Kernel panic – not syncing: Sign up using Email and Password.

How do i check whether an I2C device works? Not able to use the console BF ezbrd. If the current consumption is a result of some error the IC could die in the lan88720.

If you have any dev board then try interfacing it by using library provided by microchip. Will it work properly given the conditions above.?

Heat sinks, Part 2: However, the section of lna8720 LAN datasheet regarding Configuration Straps recommends adding external pull-up resistors to augment the internal resistor when the pin will be connected to a load. For this I had two choices.

LANA – Ethernet PHYs – Interface and Networking

It’s almost 2x the specified and I noticed that the IC is a little hot. TimB 2 8. Resistors R11 R12 R14 have different value if we compare it to Microchips schematic. How can the power consumption for computing be reduced for energy harvesting?
