Hello.
The board was not in working condition before. We received an unused/new board, unpacked & followed the first steps (connecting cables, configure serial terminal, boot sd-card) when we encountered this issue. The sd-card was part of the kit received.
As a follow up, we downloaded variants of the bootloader (and linux system) and programmed some other sd-cards, to see if there was some software programming issue, but the other versions also exhibit the same symptoms.
How we verified the error; When left untouched, the system does not boot (Memory Calibration Failed). Resetting the board always leave the system in the same state. By applying pressure on the memory chips the system does boot. If we, at any point, release that pressure, the system fails.
This can be observed in the videos attached.
Thanks for your time.
Regards
Andreas
