[PATCH v3] Improve handosff prepare on SoCFPGA

[PATCH v3] Improve handosff prepare on SoCFPGA

[Brian Sune]

There are some cases that the Python scripts
are run and the qts files are not replaced.
Make sure qts folder h files are removed before
handoff script runs.

Typo in commit message: "handosff" should be "handoff".

HANDOFF_KEEP defaults to "0", so -n "0" is always true. I suspect you want:

    if [ "$$HANDOFF_KEEP" != "0" ]; then \

Otherwise the 'preserve' path is always taken and the 'clean' path is dead code.

You could also have an empty variable meaning don't keep.

The trap is set after TEMP_DIR has already been used. If the python
script or mv fails partway through, the temporary directory won't be
cleaned up. You could move the trap to immediately after mktemp

Hi Simon,

Thanks for the feedback.

Before the patch was pushed I personally tested all these cases and
found no issue.
make w/o HANDOFF_KEEP=1 will link to clean vice versa.
You can use make HANDOFF_KEEP without =1 it will report
No rule to make target 'HANDOFF_KEEP'
Sorry, cannot see issue on this section.
Maybe you can try and test if it is the case.
Pure "brain processes code" sometimes is a bit tricky.

Sorry, again during the test I did not see any issue what you described.
The temp dir cleaned up w/o any issues.
Both condition branches keep and clean.
mv or python script will not break like exit 1

Hi Simon,

I think this is a misunderstanding.
My original idea is to use the HANDOFF_KEEP=(whatever is mistyped)
to run the keep branch.

While the absence of HANDOFF_KEEP(anything) will not keep.
But simply HANDOFF_KEEP will not work and need HANDOFF_KEEP=xxx.

Because the command >
"make prepare HANDOFF_KEEP=xxx" is very distinctly long
HANDOFF_KEEP=xxx so it must keep my thingy.
Even if I mistyped =0 etc.

And during the absence of HANDOFF_KEEP=xxxx
"make prepare " immediately, see ok clean so it will not keep good.

That's my original thought.
I think I should changed to:
if [ -n "$${HANDOFF_KEEP+x}" ]; then \


Need your comments on this.

Thanks,
Brian
