In meantime I found that it's possible via ST-link only: http://wiki.seeed.cc/FST-01/ also here: http://www.gniibe.org/memo/development/fst-01/dongle/fst-01-swd-connection.html so if we do new design maybe would be good to add for user possibility to update FW. >> * then I can open a shop entry for preordering >> * I can prepare production data >> * and order 2-3 samples and have them built >> * those samples go to those doing the first preorders >> * things would be tested/debugged >> * after that it is possible to provide permanent service for the community >> until components become EOL >> >> BR, >> Nikolaus >> _______________________________________________ >> Community mailing list >> Community@tinkerphones.org >> http://lists.goldelico.com/mailman/listinfo.cgi/community >> http://www.tinkerphones.org > BR,
