Which qe-ucode to use for LS1021A?

[nenadradulovic]

SDK: LayerScape LSDK-17.09

There is inconsistency in which ucode file to use for the LS1021A MPU.

The first occurrence of ucode file name is in file manifest/ls1021atwr.manifest. The ucode file is specified as:

build/firmware/qe-ucode/fsl_qe_ucode_1021_10_A.bin

The second occurrence of ucode file is in packages/firmware/rq-ucode/readme file:

P1021/P1025:  fsl_qe_ucode_1021_10_A.bin
T104x serial: iram_Type_A_T1040_r1.0.bin
T1024:        iram_Type_A_T1024_r1.0.bin
LS1021a:      iram_Type_A_LS1021a_r1.0.bin

It seems that the manifest file specifies ucode which is for P1021/P1025 MPU, while the readme file in firmware git specifies another one.

Which ucode file to use for LS1021A?

Best regards,

Nenad

Use the following command for qe microcode building:

flex-builder -c firmware -m ls1021atwr

Find QE microcode using the following path:

flexbuild/packages/firmware/qe-ucode$

See attached snapshot and readme file.

Have a great day,
