    Olimex ARM-USB-TINY-H doesn't work on WICED-Studio-6.1.


      I am using WICED-Studio-6.1 on CYW943907AEVAL1F platform.

      I can't succeed to download the image using by using Olimex_ARM-USB-TINY-H on WICED-Studio-6.1 (Windows10).

      but WICED-Studio-6.0 can download successfully.

          What is the driver that you are using for Olimex_ARM-USB-TINY-H ? Please use the driver mentioned in 43xxx_Wi-Fi/tools/OpenOCD/Olimex_README.txt and also provide the error message that you are seeing. (download_dct error? )

              I am assuming status of the SW4 is all ON and then also you are receiving this error? I tested with SDK and I was able to download successfully without manually updating the driver. For your case, you can try updating the driver by choosing the option of search automatically for the updated software in your WINDOWS 10 PC and you should be able to download if you have followed all the steps correctly as mentioned in OpenOCD -WICED

                Hi morise,


                Did you resolve "download_dct" failed issue? Because I have met same issue with you, I'd like to ask how did you resolve this issue if you resolved? I also use "libusb-win32 ver 1.2.6" and SDK 6.1.0 or SDK 6.0.0 but it still doesn't work.

                Test EVK is same with you(CYW943907AEVAL1F and Olimex ARM-USB-TINY-H). Could you give a guide?
