Hi there,  
I ported my forked U-Boot to new hardware and get the following error message when building via Yocto:

> do\_mender\_uboot\_auto\_configure failed with exit code ‘137’

Unfortunately, the message is not very helpful, any hints towards this?

Hi @buffo

Can you share more of the output? There should also be a log.do\_\* file mentioned in the output. If you can provide that it will be helpful.

I was not aware that the error code **137** is commonly used for a memory error as the build process simply crashed without further information. After that, Yocto did not output any log file that I could have provided, nevertheless it was a configuration issue regarding my debug output in combination with the CONFIG\_DEBUG\_LL flag. After a rework I was able to build again, however, I am not sure what exactly was the root cause. 🥴
