I can confirm that this works in hw2.7, but the uploading of the hex file from git is currently problematic. I deleted the html headers and footers but the file was still secretly a txt file and not a hex.
No matter what I did, win7 would add a secret .txt after the .hex so even though you see APP_G251.hex, it is actually APP_G251.hex.txt. This causes an error when uploading the file. The error will be, “Item not found, the item is no longer in computer” which seems to be caused by the dso203 rejecting the txt file.
My workaround solution to this was to download the whole zipped repository from git hub and then upload the .hex file from the bin directory into the drive named DFU V3_11_C on the DSO203. Note that the hw2.7 drive name has changed but that it doesn’t matter.
Upload was successful and now that I’ve contributed my little bit I’m off to play with my new toy. Thanks all. We’re standing on the shoulders of giants.
