Hi, Until recently (including with the RC1 release of OpenWrt Attitude Adjustment) things were working ok on the linksys e1000 (besides the things which were not ready then).
However, using recent builds of trunk (built by me, and built by http://downloads.openwrt.org/snapshots/), the serial flash does not work (for comparing, see logs from when working at https://forum.openwrt.org/viewtopic.php?pid=179178#p179178): Starting program at 0x80001000 [ 0.000000] Linux version 3.3.8 (me@mypc) etc. etc. etc. [ 0.000000] CPU revision is: 00019749 (MIPS 74Kc) [ 0.000000] bcm47xx: using bcma bus [ 0.000000] bcma: bus0: Found chip with id 0xB83A, rev 0x00 and package 0x02 [ 0.000000] bcma: bus0: Core 0 found: ChipCommon (manuf 0x4BF, id 0x800, rev 0x1F, class 0x0) [ 0.000000] bcma: bus0: Core 3 found: MIPS 74K (manuf 0x4A7, id 0x82C, rev 0x02, class 0x0) [ 0.000000] bus0: Unsupported ST serial flash (id: 0x15, id2: 0x15) [ 0.000000] bcma: bus0: Early bus registered [ 0.000000] No supported flash found [ 0.000000] No supported flash found [ 0.000000] gpiochip_add: registered GPIOs 0 to 15 on device: bcm47xx [ 0.000000] Determined physical RAM map: [ 0.000000] memory: 02000000 @ 00000000 (usable) [ 0.000000] Initrd not found or empty - disabling initrd [ 0.000000] Zone PFN ranges: [ 0.000000] Normal 0x00000000 -> 0x00002000 [ 0.000000] Movable zone start PFN for each node [ 0.000000] Early memory PFN ranges [ 0.000000] 0: 0x00000000 -> 0x00002000 [ 0.000000] Built 1 zonelists in Zone order, mobility grouping on.

It would be greatly appreciated if someone knows what is causing this regression, and how to solve it. The thread https://forum.openwrt.org/viewtopic.php?id=26896 deals with getting OpenWrt to boot on a hardware-identical router (wrt160nv3), and it seems the issue there was the flash; however, that does not explain why it was working before, but not now. I am working on this; it seems from the thread on wrt160nv3 etc. that it might be kernel config so im trying that, but even if that works, should it be re-enabled in trunk? Thanks. _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
