Hi,

Not all partitions are enabled by default in the upstream RSE FW. We’re currently working on a generic solution for FWU on RSE, hence the reason by default the RSE-specific manifest does not enable it.

Thanks, Antonio

Hello everyone,

I am inquiring about the Firmware Update (FWU) service configuration on the rdv3r1 (Neoverse RD-V3) platform.

While building TF-M for the rdv3r1 target, I noticed that the TFM Firmware Update Partition is missing from the Secure Partitions list, even though I enabled the relevant CMake flags.

Upon investigation, it seems that the build system is using the platform-specific manifest list located at: /tf-m/platform/ext/target/arm/rse/neoverse_rd/common/manifest/tfm_manifest_list.yaml

Instead of the generic tf-m/tools/tfm_manifest_list.yaml. The issue is that the platform-specific manifest list appears to lack the definition for the FWU partition. Consequently, the files under generated/secure_fw/partitions/firmware_update/auto_generated are not being generated.

Could you please clarify if the Firmware Update Service is currently not supported on the Neoverse RD environment? Or is there a specific configuration required to enable it?

Thank you.

Best regards,

JK Park
