jewgeni, seems you experience the well known sd card issue. wiki and/or archives should offer a lot of postings on the issue. it boils down to setting sd_max_clk -- in your case in the nand boot environment since your fr seems unable to boot from sd at all.
searching for "sd_max_clk +openmoko" should give you sufficient enough hits. _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
