Comment(by hailfinger):

While I do like the patch, I fear the user interface of flashrom is less than optimal in this case.

AFAICS flashrom -Er and flashrom -rE are equivalent, but user expectation is completely different. Can we honor the order of commands or at least place reading before erasing and writing?

The best solution would be making -r and -E mutually exclusive like -r -and -w are.

Comment:

This allows -Er -Ew and -Ev but they are pretty useless. The point is that this allows -Ewv which will test erase, write and read (both during erase and verify) operations on the probed flash chip, so it's an easy way to exercise flash chip drivers.

Currently the order of commands (-E -r -w -v) on the command line is not significant, if multiple commands are specified flashrom will always execute them in order ERASE READ WRITE VERIFY.

This can be bad for users running -rE expecting to get a backup before the erase is done. A simple solution would be to change the order in main() into READ ERASE WRITE VERIFY, in which case the invocation:

flashrom -rEwv org.bin

will save the original contents, erase the chip and write back the original, verifying each step.

Comment:

As you said, the new "features" introduced by the patch are rather useless.

If this is about making testing easier, what about explicitly creating a " --test" option that does things in a defined order. Then we don't have to worry about doing implicit things.

Comment:

I suggested adding -T in #106 (dup of this) and I closed it because the patch suggested here achieves the same thing but with the user interface -Ewv (already familiar options) instead of -T (which would be new).

But if everyone is really serious about restricting what flashrom lets the user do - unless it is invoked a special way - I guess that's what we have to do, but I think it's silly. Let user shoot foot if they try - that's why I fell in love with UNIX anyway.

(And I don't think simplifying the test procedure from many flashrom+hexdump commands into a single flashrom command is minor, so changing prio back.)

Comment(by hailfinger):

Moving read before erase as a single simple patch is

Acked-by: Carl-Daniel Hailfinger c-d.hailfinger.devel.2006@gmx.net

That leaves us with another question: Should -Erwv or any other read/write combinations be allowed? I think the semantics of read+write are totally unclear. If you perform read, erase, write, verify (in that order) it means that you just rewrite ROM contents. That may or may not be desired, but it sure would work for testing read/write/erase operations.

Comment:

It also does not necessarily do the same thing with the hardware as calling the single functions. Strictly, a reboot between any of the tests would be the most reliable way of testing flashrom.

Answering Peter's concerns, if we're going to add a method of "simplifying flashrom tests" that is a new feature, and it should get a new option. Using -Erwv for that ignores that fact by adding a lot of implicit assumptions. Implicit assumptions are fatal for any user interface.

Strictly speaking, -wv should be disallowed, too. Instead, write should guarantee that the write succeeded, or print an error otherwise. As should an erase make sure that the chip is erased, if the program exists without error.

Other than that, we should stick with the small utility approach, and have the tool do one thing at a time.

Comment(by hailfinger):

We now have auto-erase for write and auto-verify for erase and write.

Combining -Erwv does not make sense anymore, but a separate -T parameter for a full test would indeed be helpful. Not sure if I should close this ticket.

Comment:

Given that chips now support multiple erase functions, testing is way more complicated. We need a separate -T, everything else will only give us incomplete test reports.

I have a patch for this, but it needs partial write support, and that will be added post 0.9.2.
