The cause for this weird behaviour is that I had PCI_ARBITER_EN_ disabled. So, a HW problem at the end. I had disabled it trying to reduce power compsumption due to the PCI, as I am not going to use it. It seems it is not possible that way.

You are right. Thanks so much for your help. Best regards, Alex
