3.1 Upload command
Figure 4 illustrates how to upload a copy of the internal Flash memory.
Figure 4. Upload command flowchart
Note: 1 BUFFERSIZE is a user-defined variable in the “usbh_usr.h” file that can be modified at
compilation. BUFFERSIZE = 4 * x; where x = [1,8192] limited by firmware.
2 With BUFFERSIZE = 4 * 8192 = 32 Kbytes, uploading of all Flash memory takes about 2
seconds.
3 When the user selects the Upload command, the old “UPLOAD.BIN” file will be deleted and
replaced by a new one that contains the new Flash memory data.
