Hi to everyone
I have my Cyclone5 board (inspired to Terasic)
I obtained a SD card with Angstrom 2018.06, DTB obtained from my hardware and it boots ok: Eth0 (I use in GMII) is correctly ack, DHCP runs fine and eth0 is on line.
After some modifications on HPS QSYS to add lightweight HPS interface (these mods doens’t affect eht0) linux boot but Eth0 seems going to RGMII (uncorrect) and it is not running!!
My difficult is how to define a XML BOARD INFO FILE clearly! There isn’ a doc about write well this complex file! I forced Eth to GMII modify the rows from RGMII to GMII
It runs fine on first attempts, but today Linux seems puts it in RGMII anyway ( I see with SignalTap that my HW EHT0 data bus move only first 4 lines… probably it is RGMII but I have only GMII)
How I can say to linux with XML (–>DTB) to open eth0 in GMII fixed???
Thanks to anyone for suggestions!!!
