I am not subscribed to linaro-dev, so please Cc me in case you drop flashbench-results mailinglist from receivers. Hi Arnd, hi everyone! For now quick and short. A simple script to automate common steps on reporting flash medium test results. It goes as far as read tests for erase block size and then suggests some open au tests together with a warning that these write to the device. I checked other flashbench-results posts as to what info would be interesting. Find it at: git://gitorious.org/flashbench/flashbench.git Example output is at: [Flashbench] Samsung Plus MB-SPAGFFP Class 10 SDHC 16GB Sat Dec 1 16:02:18 UTC 2012 http://lists.linaro.org/pipermail/flashbench-results/2012-December/000346.h… Sorry that I occupied flashbench upstream name for project. I can look into renaming it to "flashbench-martin" or something like that. The script is in branch "flashreport". In branch "defaultblocksize" you find a currently untested patch for changing default block size to 1024. I can try to send patches as mails via git, but I´d have to look it up first, since I do this quite rarely. Up to then please use the repo urls :) Nice weekend, -- Martin 'Helios' Steigerwald - http://www.Lichtvoll.de GPG: 03B0 0D6C 0040 0710 4AFA B82F 991B EAAC A599 84C7
