During the last week, I used my Lab Switch to run power-cyling tests on Milkymist One. The objective was to better understand the properties of a NOR corruption we had observed in manual testing, and to validate the fixes or work-arounds we have devised.
The tests confirmed several of our hypotheses. So far, they did not yield a conclusive result for the work-arounds, because the NOR corruption failed to re-appear in what should have been a final set of tests without all the countermeasures. To be continued ... A log of the testing process, along with some technical details on controlling M1 over JTAG, can be found here: http://projects.qi-hardware.com/index.php/p/wernermisc/source/tree/master/m1rc3/norruption/LOG Last but not least, I made an overview page for the Lab Switch: http://downloads.qi-hardware.com/people/werner/labsw/web/ Coming next: I'm in the process of fixing some flaws of the Lab Switch and of tightening the BOM by replacing parts from local sources with parts from Digi-Key. Once this is done, I'll make a new version that should then also be buildable anywhere else on the planet. - Werner _______________________________________________ Qi Hardware Discussion List Mail to list (members only): [email protected] Subscribe or Unsubscribe: http://lists.en.qi-hardware.com/mailman/listinfo/discussion
