Hi Jerome, I'm working with a board that has an IMX ENETC MAC on it drivers/net/fsl_enetc.c and when configured for LWIP it fails and warns about RX buffers not being 64B aligned: WARNING at drivers/net/fsl_enetc.c:776/enetc_setup_rx_bdr()!
I tried changing MEM_ALIGNMENT to 64 in lib/lwip/u-boot/lwipopts.h but that did not align the buffers to 64B. Where are the lwip buffers created and do you have any suggestions for working around this? Best Regards, Tim
