This is a very odd request. I could see this as a "challenge" just to see what it takes and if it's possible... Maybe make a forum thread too? Since you went for 2,5" and 3,5" drivers, you could get cheapish (~10-20 € on ebay) ready-made minipcie<->sata adaptors available with Marvell brand chips that have 2/4 SATA-Ports (whatever fits). With those you should be able to just fire up OpenWrt and load kmod-ata-ahci to get access to the connected SATA drivers with much less hassle. (And the Marvell chips should support SATA-3 + NCQ. The DesignWare IP-Core inside the APM82181 can only do SATA-2 and the driver does not have support for NCQ). Come to think about it, I have one of those minipcie<->sata thingies at home, I could try this with a WNDAP620 and a WD HDD. (I don't have any of those mini sata ssd, so I can't try that). > Does DesignWare SATA on the APM82181 require U-boot's involvement to > initialize? Or am I missing something from the OpenWrt side? Yes, there's some special sauce in Uboot. You could look at the Netgear's WNDR4700 UBoot (uses both pcie + sata) and the MyBook Live DUO. Both Uboots sources are part of their respective GPL drops. The MX60(W) also has its uboot available on github... And I think (I don't know 100%) there was some commented code about setting up SATA. > Would attempting to boot Debian instead be a good idea? If you are looking for Debian on APM82181, I've made a "build-your-own-debian" for the MyBook Live (DUO). <https://github.com/chunkeey/mbl-debian> You cloud swap out the MyBookLive.dts with that of the MX60(W) and change the uImage packaging a bit to get a kernel that you can put in the NAND to boot off. But yea, you could have a good shot at running Debian SID on the MX60. Cheers and Have fun with your SATA-on-MX60 Project, Christian _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
