Hi, I just randomly bumped into this contents.xsd XML Schema: https://qartifactory-edge.qualcomm.com/artifactory/qsc_releases/software/chip/qualcomm_linux-spf-1-0/qualcomm-linux-spf-1-0_test_device_public/r1.0_00095.0/qcm6490-le-1-0/common/build/lib/contents.xsd Just a few minutes after we landed support for generating contents.xml files: https://github.com/qualcomm-linux/qcom-ptool/pull/29 I believe qcom-ptool should validate the contents.xml files with this xsd. I'm not yet sure where the latest version is being maintained though.
