Hi,
It seems that the intention is to pass bootcode to dsp_upload_sections_api, but it is still using the hardcoded dsp_bootcode.
Yes indeed, nice catch.
however that code is purely theoritical because that particular code would only work on development calypso devices anyway. (the other boot a hardcoded boot loader whatever we do)
I fixed it anyway in git.
Cheers,
Sylvain
