You reported the same issue some time ago [1] and while I could fine the original thread in my inbox, I thought we had got to the bottom of the issue and it had been fixed I couldn't find a follow up thread. Maybe Fabio can remember as I seem to recall he was the one that got to the bottom of the issue. Peter [1] https://lists.denx.de/pipermail/u-boot/2023-November/538832.html
