After uploading DFOTA file in Eg25 Modem We get following error when AT+QFOTADL command sent
We get +QIND: “FOTA”,“END”,502 response. Which means “The upgrade process exits for some unpredictable errors”
Can any one tell why the firmware update failed here?
We have implemented following process for firmware download:
Delete file if already present in UFS.
it gives CME Error 418
Then Upload file
After successful file update
+QIND: “FOTA”, “END”,502
on next retry it gives
+QIND: “FOTA”, “END”,510
The error code 510 means that the patch does not match the source file in the module, need to check whether the upgrade package is wrong.
Please follow up the DFOTA user guide document to check the DFOTA package, the path and the whole test process. Thanks!
