Hi Kevin, I have this board so can help. I’m sure its got the same firmware as yours and does work, let me dig it out, connect it up and I’ll come back here shortly.
Okay, I’ve connected mine to a Windows 10 PC and have this in my MBED.HTM file:
<!-- mbed website redirect -->
<!-- Version: 1.4.2. build 352 -->
<meta http-equiv="refresh" content="0; url=http://mbed.org/device/?
<title>mbed Website Shortcut</title>
Compiled the demo (that’s using mbed os2 classic official library) and saved directly to the TB2 and is working.
I’ll try reloading the firmware on Simplicity Studio again and see what happens.
I can see I can roll back to previous versions in Simplicity Studio, can I suggest to roll back to the previous version, try it again on mbed and then reload the up to date version.
Tried that but couldn’t roll back the firmware, I think it only goes one way. However I loaded the TB sense 2 demo on Simplicity Studio that the board is shipped and that loaded and worked okay, so I suggest to try that and come back here…
