Layerscape LS1012A RCW/PBI (PBL image) byte-swapping

Layerscape LS1012A RCW/PBI (PBL image) byte-swapping

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!

Hello Tim,
Rcw has been swap .
You can see the below recipes.

https://git.yoctoproject.org/cgit/cgit.cgi/meta-freescale/tree/recipes-bsp/rcw/rcw_git.bb

do_install () {
    if [ ${M} = ls2088ardb ]; then
        oe_runmake BOARDS=${M} DESTDIR=${D}/boot/rcw/ install
        oe_runmake BOARDS=${M}_rev1.1  DESTDIR=${D}/boot/rcw/ install
    else
        oe_runmake BOARDS=${M} DESTDIR=${D}/boot/rcw/ install
    fi
    for f in `find ${D}/boot/rcw/ -name "*qspiboot*"`;do
        if echo $f |grep -q "qspiboot_sben"; then
            continue
        fi
        f_swap=`echo $f |sed -e 's/qspiboot/qspiboot_swap/'`
        tclsh ${STAGING_BINDIR_NATIVE}/byte_swap.tcl $f $f_swap 8
        mv -f $f_swap $f
    done
}



thanks

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?

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
