Nano upload just started failing

[larvelljones]

Hi,

I've been using Ardunio 1.8.x for a while now with no issues. But today after a (what seemed like) successful upload, no further uploads would work. Would just hang. Scoured through the forums, found an article about upgrading to the latest Ardunio ide and hitting the reset when it's uploading…. but that didn't work either.

Here's the output I'm seeing now if I just let it go without the reset. Any ideas?

Do you have the correct board and com port selected? Does this also happen on a different board, or is this isolated to this particular board?

Just to verify, you are using a Nano 33 BLE.

Try double-tapping the reset button right as the compile finishes and the upload starts.

you're a genius. the double tap worked. Thanks!!

On some of the arduino boards pressing the reset twice puts the board in bootloader mode, useful when the code running on the board somehow prevents the normal automatic reset from working properly.
