Ethernet camera module build log #3 – Network

Was debugging strange Ethernet behavior. The driver reported the opposite status of plugged RJ45 cable. It turns out I did not have a 100M RJ45 connector with integrated transformer and soldered 1000M by mistake. Good thing Würth Elektronik delivered new connectors very rapidly.

And after a quick rework job network is alive! JBC C245-949 cartridge was very hadny to de-solder RJ45 connector without damaging board nor connector.
