Flashing fails for iSense node #5

Closed danbim closed 13 years ago

danbim commented 13 years ago

I tried to flash an isense node using the flash utitlity from http://github.com/itm/wsn-device-utils/. It failed with the following errors:

java -jar wsn-device-utils-0.3-SNAPSHOT-flash.jar isense /dev/ttyUSB2 vlinks.bin

Try again to flash or reconnect the device. I had the same error, but it was not deterministic. I will take a look again.

Problem currently only occurs on Linux 32bit Systems.

Problem solved. The fix was simple. I added a connection.flush() after the program mode was entered. It seems that Linux buffers the data before the programming mode was entered windows does this not.
