It would be helpful to get a more information about your setup.

It seems to me like you are trying to use the AmbiqSuite SDK to compile and upload “example1_edge_test” to an Edge board.

You mention that you’ve changed the baud rate to 115200 for upload – does this mean you’ve tried at 921600? Know that there are two variations of the Edge board. Those obtained from the TensorFlow conference use 115200 baud and those ordered from SparkFun use 921600. You must use the appropriate baud rate for the board that you have. Additionally there is a known problem with USB-serial drivers on some operating systems (Linux primarily) that can cause bootloading to fail at 921600. See the other forum posts about this topic:

i got the one from sparkfun so i have restored the baud rade to 921600 but still it show me this error:

PS I’m using window 8.1 with git bash installed

and also i have closed my serial terminal on arduino when uploading the code .

Could it be due to the fact that arduino doesn’t have a option for 921600 baud rate ,then what should i do if that’s the case.

Solved i connected the serial basic to edge board in wrong orientation that’s the reason for error.

Thanks for letting us know – this one was stumping me and I couldn’t reproduce. Glad that it is working now!
