I am currently working with the TE0703 carrier board and TE0820-04-3BE21MA module, attempting to boot from an SD card.
Steps I have taken so far:
I downloaded the prebuilt ZIP folder from the following link:
Trenz Reference Design 2024.2
Inside the downloaded folder, I navigated to:
prebuilt → boot_images or OS or hardware → 3eg_1e_2Gb (since I have the TE0820-04-3BE21MA).
I copied the necessary boot-related files onto a FAT32 partition on my SD card.
I ensured that the DIP switches were correctly set for SD card boot mode.
I connected the TE0703 to my PC via a Micro-USB to USB cable and opened a serial terminal (PuTTY/Minicom).
Observed Behavior:
No output appears on the serial terminal.
LED D1 and D3 remain red.
LED D2 (green) blinks intermittently instead of staying continuously lit, which I understand should indicate a successful boot.
The Ethernet LEDs are continuously orange, suggesting that the DIP switches are correctly configured.
Is there any step I might have missed? Could you provide any guidance or documentation to help troubleshoot this issue?
Thanks a lot for any helps , ( i'm a beginner in Trenz board )
