Alternatives? X-SW-Source: 2005-06/txt/msg00114.txt.bz2 Hello Gary, thanks a lot, you helped clear some of the confusion. In case anyone else is interested in this: There are some redboot images and .ecm files with flash support for ARM E7T at http://www.sweeneydesign.co.uk/downloads.htm I have found an earlier post with some links that did not work, so you may want to try this one. The image executes and the fis commands are available. Also, Redboot's fconfig seems to offer the solution to "scripted booting". However I have not tried it out yet.
