Introduction This work is sponsored by Reliable Embedded Systems . You can find more information about our training/consulting services here . Objectives The goal of this blog post is to show how to build an image for Analog Devices ADSP-SC5xx chips and how to deal with ancient versions delivered by Board/Chip vendors. Please let them know that you are not happy! Let the party begin System setup In case you wanted to build for ADSP-SC5xx Processors you might want to have a look  here . repo init -u https://github.com/analogdevicesinc/lnxdsp-repo-manifest.git -b release/yocto-1.0.0 repo sync So far so good. All this does not look too old with the latest commit on the manifest file from   Jul 23 2020  but if you look a bit further you'll see that the Yocto version is thud.

As an example let's take recipe A ( u-boot-phytex-imx ) which needs the output of recipe B ( firmware-imx-8m ) for a successful compilation. (Please don't ask why.) To be more precise here is an excerpt of recipe A ( u-boot-phytex-imx ): # --> this funny u-boot from Phytec needs the ddr_firmware binaries in ${S} # Note: here we copy deployed stuff from another recipe # to the source dir of this recipe! # # DEPENDS deals with build-time depenencies # Read my blog post to find out why DEPENDS does not work here # # DEPENDS += " \ # firmware-imx-8m \ # " # RDEPENDS is wrong anyhow for what I want ...
