FS#4055 - [bcm53xx] EA9500 - OpenWrt fails to boot with Latest snapshot builds #9049
Comments

rmilecki: This should be fixed by the commit b2cfed4 ("Revert "swconfig: fix Broadcom b53 support""). |

npcomplete: Thanks Rafal for fixing the bug. The router now boots, but it doesn't detect the second switch. Should I worry about this?

npcomplete: Also, do we need to change this to switch0 since now there is only one switch detected?

rmilecki: Northstar's MDIO at 0x18003000 is DT-defined and its external MDIO at 0x200 is DT-defined as well. The only sane way is to describe BCM53125 in DT (as it's done right now in the bcm47094-linksys-panamera.dts). To support DT-defined MDIO device (and BCM53125 is an MDIO device - not a PHY device) we need MDIO driver. OpenWrt's downstream swconfig-based b53 doesn't behave as MDIO driver. It registers as PHY driver. It can't be used in its current from to support EA9500's BCM53125. We have two options:
I'm planning to switch whole bcm53xx to DSA so I think that working on downstream swconfig-based b53 is waste of time. Give me few more weeks to sort out remaining bcm53xx issues and we'll get BCM53125 support for "free" soon. |

npcomplete: More than happy to wait for DSA. Thanks! |
