• I wonder whether the USB bootloader is corrupt. The firmware should have been verified, but I wonder whether Seeed decided to leave off that step because it took too long :(

    Can you try running the following code:

    var crc = 0; for (var i=0x08000000;i<0x08002800;i+=4) crc = (crc<<1)^(crc>>63)^peek32(i); console.log(crc);

    And let me know what the result is? I get 2628236757068185765 here.
