Uploading failed

Dear All,

I am writing to you because I am experiencing problems with uploading code to CC3200 module.

I have purchased the RedbearLab WifiMicro Kit (http://www.exp-tech.de/en/redbearlab-wi-fi-micro-kit) which worked for a few uploads but after that I had the following error:

//---------------------------------------------------------------------------------------------------

After a few uploads both the WifiMicro and the MK20 Usb dongle stop functioning. I cannot see the MK20 at the Com Ports anymore.

So, instead of using the MK20 to upload code I used the FTDI Friend by Adafruit and  I connected (GND, CTS, VCC, Tx, Rx, RTS) of the FDTI to the corresponding pins of the WifiMicro (GND, NRST, VDD, Rx, Tx, D13) http://discuss.redbear.cc/t/cc3200-wifi-micro/897. Unfortunately I am getting the following error in uploading ...

Any help will be really appreciated!

Best,

George

Hello,

Thank you again for your reply.

I finally made working the MK20 usb dongle by updating the firmware with my laptop and then worked to my office PC.

Regarding the upload to the WifiMicro after a lot of uploads and resets I finally uploaded code successfully with the following message which will be sent to the Energia by RedbearLab for debugging ......
