Hi Heystek, Thanks for the reply and the link. The memory error appears immediately after the roach is turned on, before the option to stop the autoboot appears. Sometimes it does continue a bit beyond that before stalling, so I’ll look at trying to do a uboot update when it next does that.
The links to the images on the webpage don’t work (the casper svn no longer exists?), are the latest versions stored elsewhere now - perhaps they the ones on the ska-sa git?
