That would be https://git.codelinaro.org/clo/la/openocd-org/openocd/-/blob/qcom_changes/README_QCOM?ref_type=heads Which says: Qualcomm specific tools: - Login to qpm.qualcomm.com - QUTS: 1.64.1.39 (version & above) - Qualcomm Host USB Product Suite - QUD QC only : 1.00.63 (supported version) - EUD QC : 2.1.1 (supported version) I believe the specific versions of QUD and EUD are only available to Qualcomm engineers and not even to OEMs, though I might be mistaken.
