The error message you’re encountering indicates that the -mtune option in your U-Boot build process is set to an invalid value, generic-armv7-a. The valid values for -mtune are specific ARM cores and architectures, as listed in the error message.
To resolve this issue, you need to specify a valid -mtune value that matches the architecture of the target device you are building U-Boot for. You can do this by modifying the U-Boot configuration or the makefile where the -mtune option is set.
Here are some steps you can take:
-
Identify the Target Architecture: Determine the specific ARM core or architecture your target device uses. This information is usually available in the device’s datasheet or technical reference manual.
-
Modify the Configuration: Once you know the correct architecture, update the U-Boot configuration to use a valid
-mtunevalue. This might involve editing the configuration file or the makefile where the compiler flags are set. -
Rebuild U-Boot: After making the necessary changes, clean the build environment and rebuild U-Boot to ensure the changes take effect.
If you are unsure about the correct architecture for your device, you may need to consult the documentation for your specific Toradex module or reach out to Toradex support for further assistance.
