Changes

To reprogram the CW1101, you simply need to force the ERASE. This is done by shorting the "ERASE" jumper on the bottom side while plugging in the USB. This is easier to do by inserting the micro-USB end into the CW1101, and leaving the full-sized end not plugged into the computer. While shorting the ERASE jumper with tweezers have someone plug in the full-sized USB. The device should re-enumerate as a serial port, and the USB LED will be off or dimmly dimly lit. == Beta Versions == There exist TWO beta (pre-release) versions floating around. The two versions were released at these events: # CHES 2018 version# arm TechCon version These versions have some limitations. First, they have not been well tested and were not built under the normal production processes, so are not guaranteed to be as reliable w.r.t. soldering. Second, they have some specific hardware changes relative to the production units: # arm TechCon and CHES version (-02 and -03 PCB revs): If you cut/snap the target off, the GPIO4 (trigger) pin is not connected. As this pin is required to be used for the ADC trigger, we recommend not cutting the targets off these versions. The GPIO4 trace is incorrectly routed THROUGH the target section. If you'd like to use an external target, either erase the STM32F0 or remove the IC.# CHES version (-02 PCB rev) does not have the amplifier on the front-end. This results in poor analog performance.
