Hi, Ed, I am using mine u-boot with few fixes, it's not without bugs, but it probably has less bugs than openmoko's u-boot: http://wiki.openmoko.org/wiki/U-boot-gena2x Also i'd suggest to try reducing sd card clock in kernel params (in u-boot env, glamo_mci.sd_max_clk=15000000). And do backups. I am just removing sd card and do full dd dump of contents to hdd, this takes 10 mins, but 100% error-proof, easy, fast and painless recover. without any problems with partitions or anything else. Gennady. _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
