Hello,

When I connect an ethernet cable to the expansion kit, the RJ45 LEDs are not lighting, it that normal ? they are lit once, but after never even disconnecting the board. that's strange !

With a PIC32 starter kit when I plug an ethernet cable, the RJ45 LEDs are lighting and/or blinking.

I can't test an Ethernet project right now because I have other things to do.

I want to ensure that the expansion kit's ethernet PHY module is not defective.

Thanks in advance for your support.

The STM32F4-DIS-BB, or something else?

Aren't there code example that could be tested quickly?

Generally you'd need to configure (pins, clocks, mode) and drive the negotiation of the external PHY in your code implementation, and recognized cable in/out events and renegotiate.

yes, STM32F4-DIS-BB (from element14)

so you think it's a normal behaviour ? because as I sais, with a PIC32 ESK (microchip) when you plug an ethernet cable its LED begin to light, blink or both...

I'm new to STM32 MCUs so before playing with Ethernet, I should play with GPIO and the other peripherals, by the way, I'm using open source tools to develop with that target (Eclipse, OpenOCD, GNU ARM tools etc... it wasn't easy to fix 😉 )

Everything's ok !!! now the connector LED's are lighting !!!

I think because STLINK driver is installed on my computer !
