OTA on imx8qm

krushnali — Fri, 09 Jan 2026 15:39:59 GMT

I have been trying local ota package update on imx8qm but failing. The package does not verifies on update_engine_client

[INFO:update_engine_client_android.cc(261)] Payload is not applicable. [ERROR: update_engine_client_android.cc(316)] Status(-8, EX_SERVICE_SPECIFIC): '21: Failed to parse payload header: Error

Code::kDownload InvalidMetadataMagicString'

[INFO: update_engine_client_android.cc(354)] Command took 15 ms

Please tell me what i am doing wrong. The same happens for both imcremental and full ota.

Hi,

Please use below command to perform OTA.

update_engine_client --payload=file:///data/ota_package/payload.bin --update --headers="$(cat /data/ota_package/payload_properties.txt)"

Best Regards,

Full ota is working fine. Incremental is accepted but does not start.

Update_engine_client --payload=file:///data/ota_package/payload.bin --update--headers="$(cat/data/ota_package/payload_properties.txt)"

Hi,

Can you wait for more time and then check the logcat output?
