As many of you have reported, there is a problem in the latest run of netmicroSD boards that we did not catch. The symptoms have been well-described on the mailing list along the lines of "my new verdex boots except when it's attached to my new netmicroSD board"
If you have one or more netmicroSD or netwifi-microSD board(s) that does not function and you have not been contacted by Gumstix already on this issue, send an email to jack@... to be setup with an RMA.
Make sure to include your four-digit OSC order number in that RMA request email.
