So I tried to build u-boot myself with the CONFIG_GMAC_TX_DELAY=3 directive, and I also tried to blindly copy the SPI+bootloader from an Armbian image (in which the networking works properly), but in neither case networking works (the other aspects are fine, the system boots without problems, so I assume I did not break anything myself). So I guess the issue lies elsewhere than in u-boot (perhaps the kernel?). Marek
