I am currently booting petalinux using a TE0720 mounted on a custom board. In my boot image, I have a firmware image that should be getting flashed by the first stage boot loader. Everything seems like its working, so maybe this is a request for information.
Can someone tell me if this D5 LED is supposed to continue blinking forever? This is what I am seeing, but for some reason, I thought it was supposed to stop blinking once the firmware was programmed. I'm poking around in petalinux, and it looks like my firmware might be loaded. However, I wonder if I did everything correctly.
the TRM only says this LED is controlled by the System Controller CPLD, without reference to its expected behavior. I understand through experience and forum posts that it blinks quickly for QSPI boot and slowly for SD boot. There are also forum references to 1/8 duty cycle blinking in some cases, though I don't think I've ever seen this.
I have seen forum links to a wiki page on trenz's website, but I don't appear to have access to that. I get an Atlassian login page that doesn't appear to accept my credientials for forum.trenz-electronic.de.
Hi,
TE0720 CPLD Description is here:
https://wiki.trenz-electronic.de/display/PD/TE0720+CPLD#TE0720CPLD-On-boardLEDs
What's the status of the other 2 LEDs?
There is normally some problem in case it blinks.
If everything starts up correctly. LED5 can be controlled from user via MDIO interface, see:

Examples to get access are included into the documentation or our reference designs:
