There's also the WPSS remoteproc on this SoC, similar to SC7280/Kodiak. Using the qcom,wcn6750-wifi compatible in dt makes the wpss firmware crash soon after boot with the following errors: [ 1263.547381] ath11k 17110040.wifi: wcn6750 hw1.0 [ 1263.577281] remoteproc remoteproc2: powering up wpss [ 1263.814337] remoteproc remoteproc2: Booting fw image qcom/milos/fairphon= e/fp6/wpss.mbn, size 8229144 [ 1263.817861] PDM: no support for the platform, userspace daemon might be = required.

Anyone have an idea how to debug this? Unfortunately my AMSS sources do not include any sources for WiFi, it's just prebuilts. Regards Luca
