If there is more folder like the previous path, it because the BoardManager doesn't uninstall previous version, simply install newer one, confusing the IDE. In such case, do a backup just in case, and delete the older one. Restart the IDE, and try again if esptool is producing 1 or 2 binaries.

I've just managed to dulipcate you error message. Got that with the "upload speed" set to 9600 as oppossed to the 115200 that I normaly use (having tried all speeds to duplicate your fault, those were the only upload speeds that returned the fault & worked respectively).

And only a single binary, but there may have been a second if this had flashed.

Check the ESP package in the folder such as ~/.arduino15/packages/esp8266/hardware/esp8266/1.6.5-947-g39819f0/.
If there is more folder like the previous path, it because the BoardManager doesn't uninstall previous version, simply install newer one, confusing the IDE. In such case, do a backup just in case, and delete the older one. Restart the IDE, and try again if esptool is producing 1 or 2 binaries.

I'll check that tomorrow. Thanks.

- Sun Aug 23, 2015 1:04 pm #26899 Today I attempted to revert to IDE 1.6.4 in case upgrading to 1.6.5 is what has been causing my issues. If so, it might explain why, at one point, I was able to upload and run sketches on my desktop PC but not my laptop. Perhaps I had forgotten which versions were installed on each machine. Maybe the desktop was on 1.6.4 and the laptop on 1.6.5, and sketches uploaded on the desktop ran but sketches uploaded in the laptop did not. Maybe I then upgraded the desktop to 1.6.5 and sketches uploaded with that machine stopped running too.

However, have run into a problem. I installed 1.6.4, selected "Generic esp8266" and attempted to compile a simple sketch but got:

Code: Select allCannot run program "/home/paul/.arduino15/packages/esp8266/tools/xtensa-lx106-elf-gcc/1.20.0-26-gb404fb9-2/bin/xtensa-lx106-elf-g++" (in directory "."): error=2, No such file or directory

Thinking this was a problem between 1.6.4 and the current esp package, I re-installed 1.6.5, but still got the same message.

Can anyone suggest how I fix this?

Thanks

- Sun Aug 23, 2015 1:24 pm #26901 OK, I fixed that error. The directories under /home/paul/.arduino15/packages/esp8266 had got messed up somehow. I deleted them and re-installed the esp package using Board Manager. Sketches compile again with 1.6.5.

So... I removed 1.6.5 and installed 1.6.4. Its no different to 1.6.5 in that my sketch uploads but does not run.
