OK.

No problem, I just wasn't sure how handle this.

I'm now trying to run moveconfig as follows

$ grep -l "ARCH_OMAP2PLUS\|ARCH_AT91" configs/* | ./tools/moveconfig.py -s ENV_OFFSET ENV_SIZE ENV_SECT_SIZE -d -

but the command hangs infinitely.

If I run it for all boards without "-d", it starts processing and gets
through about 50 configs and then hangs too.

Any idea what may be the cause?

I'm using python 2.7.16rc1.

Thank you, I'll take a look at it one I get that far.

Best regards
