Looking down the history for SRC_URI I can see that meta-atmel (which I assume 
is the vendor layer you mention) *setting* SRC_URI to a value, after your 
append operation, which explains why your value is being wiped out. This also 
tells me that the priority of your meta-atmel-lsp layer is lower than meta-
atmel, which is probably not what you want. I would suggest setting the layer 
priority in meta-atmel-lsp's conf/layer.conf so it is higher than the layer 
priority of meta-atmel, which will mean that meta-atmel-lsp 's bbappend will 
be applied second.

Cheers,
Paul
