Hello Michael Haberler:
I have tried to write other image to the SD card's boot partition with
bmaptools.If I write other image,the SD card would be ok and it can be
found by system.So I think may be the image damaged while I
download,because the download speed was very slow that time.I download the
image through the url you given again,but it doesn't work again.I think may
be the image is wrong.
