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

You can see the below recipes.

tclsh ${STAGING_BINDIR_NATIVE}/byte_swap.tcl $f $f_swap 8
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

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!
