Hello Tim,
Thank you for your commends.
You are right.
LS1012A rcw do not be swapped .
You can swap by the below command :
tclsh ${STAGING_BINDIR_NATIVE}/byte_swap.tcl $f $f_swap 8
Rcw new code  will include auto swapped binaries for qspiboot during install target

I will submitted patch for new rcw code .

Thanks
Chunrong

        mv -f $f_swap $f
    done
}



Thank you for the pointer. I might have seen that before, but never investigated why it is not working for me.

None of the LS1012A board RCW builds result in a file name with "qspiboot" in them. Therefore, this step is not done for the RCW files generated for these boards.

I see that many other LS1 boards get "qspiboot" in the file name (ls1021a*, ls1043a*, ls1046a*) but I have not figured out how/why.

The ls1012a* boards all have a qspi_endianess.rcw snippet with the same commands:
      .pbi
      write 0x550000, 0x000f400c
      .end

Is this supposed to take the place of the byte_swap script?


thanks
chunrong

The RCW/PBI file needs to be byte-swapped before being written into the QSPI flash.

Is there a reason why this step has not been included in the Yocto recipe that builds it?

Thanks!
