Hi,
Sorry for bringing up an old thread, but I am also interested in understanding the specifics for blink patterns.
My company has developed a product based on the CM4 and is using a LAN7430 PCIe Ethernet controller to establish a second Ethernet port on our device. Our Ethernet traffic is moving normally, but I want to set up both RJ45 LEDs to use the same blink patterns.
It seems there is an older convention of link/activity, link100/activity, link1000/activity, link100/link1000/activity, etc where the LEDs being on indicates a Link is active at that speed, and the LED will blink indicating activity at that speed. This appears to be what the Pi3B+ uses, as well as the LAN7430. However, I'm not sure how to map these behaviors to the newer Pi4 LED config options.
Would it be possible to provide the definitions for each of the Pi4 LED configuration options, so that I can select the LED mode that works best for our application? Specifically, I'm not clear on what Speed and Flash indicate.
Here's my incomplete understanding:
Pi4/5
0=Speed/Activity (???)
1=Speed (???)
2=Flash activity (What is flash in this context?)
3=FDX (Full Duplex mode is active)
4=Off (force LED off)
5=On (force LED on)
6=Alt (???)
7=Speed/Flash (???)
8=Link (1000: link LED -> I assume this means the LED is solidly on if a 1000Mbit link is active, which matches my observations on both CM4 and RPi4B)
9=Activity (blink for ethernet activity at any speed)
