Re: [OpenWrt-Devel] ar71xx: Update to 3.14 [Flash Erasing / Bandwidth ]
Hi Daniel, thanks for the hint. I will check it the next days. I'm now a bit busy. Also I noticed that TCP throughput went from 15MBit/s PPPoE to 6 MBit/s. It seems it is about codel, because all streams get the same rate, if using multiple. I jut want to share my expierence with 3.14 so the developer has some hints.

Also the message about the EOF marker is not displayed. Has there something changed between 3.10 and 3.14?

Re: [OpenWrt-Devel] ar71xx: Update to 3.14
Hi Andre! Does the bootloader itself support UBI? If not, flashing a raw ubinized image directly to NAND might or might not work, depending on whether the NAND chip got any badblocks on areas used by UBI. Building a UBI-capable U-Boot loader (either to replace the factory loader or as a 2nd stage loader) is one way to solve this, booting an kernel+initramdisk installer to perform the initial ubiformat is another way. Hope that helps! On Sat, Aug 09, 2014 at 01:06:41PM +0200, Andre Valentin wrote: Hi Felix! I saw that you upgraded ar71xx to 3.14. I tested it immediateley, of course.
