- Sat Oct 10, 2015 3:28 am #31006 Hi,

I installed Sming useing Chocolatey before summer and got it to work useing the esp_iot_sdk_v1.1.1_15_06_05 and it works fine.
Now I'm trying to get the latest version of sming (master branch on github) to work on an other computer but the ESP does not seem to boot up at all.
I have tried with different SDK versions without any changes in the behaivor, now I am usieing the 1.3 version downloaded from http://bbs.espressif.com/viewtopic.php?f=46&t=919

It is exactly the same behavior independent on which program I download, in the example below I use the BasicSerial.

This is the output on the serial port at 115200 baud:

The two blocks starting with "ets Jan 8 2013" repeates every 12 seconds.

Can someone please guide me in the right direction on how to solve this?

I am using an ESP-12 module with 512 kb flash, the exact same HW works with the old installation.

I solved the issue, I was using the default location of sming (c:/tools...) in the make files and not the latest version I tought I was using, by changing SMING_HOME to the correct path every thing works fine
