In the full package from the maple-IDE the upload works fine.</p> <p>The problem was in the make file :<br /> $(SUPPORT_PATH)/scripts/reset.py &amp;&amp; \<br /> sleep 1 &amp;&amp; \<br /> $(DFU) -a1 -d $(VENDOR_ID):$(PRODUCT_ID) -D $(BUILD_PATH)/$(BOARD).bin -R</p> <p>The timing between "reset.py" and "dfu-util" is wrong. Maybe a problem from virtualization. Never mind i did the following for a solution.<br /> I wrote a little wrapper around the DFU-UTIL.</p> <p>1) update the file "libmaple/support/make/build-rules.mk"<br /> original: "DFU := dfu-util"<br /> my one : "DFU := dfu-util-wrap.sh"</p> <p>2) After that copy the following bash script into the directory "libmaple/arm/bin"</p> <p>bash-script "dfu-util.wrap.sh"<br /> Copy only the source between the dashes.<br /> Do not forget and make the file executable.<br /> Hope it helps.<br /> If you like, you can reduce the "sleep 1" to "sleep 0" in the make file.<br /> --------------------------------<br /> #!/bin/bash<br /> #title: wraper for dfu-util<br /> #autor: josef koller (vienna)<br /> #date : Dec. 2011<br /> #reason: the dfu-util ist not synchroniced by firmeware uploads<br /> # so a simple retry mechanism is built in<br /> #parms: all parms are passsed to "dfu-util"</p> <p>rc=""<br /> count=0<br /> while [ "$rc" == "" ]<br /> do<br /> count=$((count+1))<br /> if [ $count -gt 399 ]; then<br /> echo "Could not upload the file after $count retries"<br /> break<br /> fi<br /> echo -n -e "Try the upload.
