Is it just my impression or has the wifi speed decreased with that
workaround?<br>
<br>
It's especially apparent on the firmware version info. That's just
23K, but takes some seconds to load. It was slow before though, I
need to make a comparison.<br>
<br>
I hope the workaround doesn't shift the issue to core 0 (running the
wifi stack)…<br>

Yes, I suspect there is something in there related to the core.
I worry that (a) it is not as simple as 2MB/2MB, and (b) we run
code on both cores anyway. We may have just fixed the test case
(which runs on core #1), but not code running on core #0.

I tried changing CONFIG_SPIRAM_SIZE in sdkconfig
directly, but it just reset back to the default 4MB.

<div class="">So changed esp-idf

To clarify: the bug
is most likely not
restricted to the
case of building a
message in a buffer.
It can possibly
cause corruptions in
any RAM section, so
can well be
responsible for
many/most of the
unidentified crashes
and stack/heap
corruptions we're
experiencing.<br

If you'd like to
test this on your
module, configure
the project to
your wifi
credentials, then
use "make flash".
As the test
project is small,
this normally will
not erase your
OVMS config
partition, but a
backup is always
recommended.<br

I thought this
might be some
copy-on-write
bug with
std::string, but
the gcc 5.x
libstdc++ does
no longer use
that
implementation
(wouldn't be
C++11 compliant
as well). I also
tried moving all
strings to
temporary
buffers, but
modes 5 & 6
eliminated this
explanation as
well.<br
class="">
<br class="">
My remaining
theories:<br
class="">
<ul class="">
<li class="">A
task writing
out of bounds
(but only
0-bytes?)</li>
<li class="">A
hardware issue
only affecting
some modules<br
class="">
</li>
</ul>
A hardware issue
only affecting
some percentage
of ESP32 could
explain this as
well as the
strange heap
corruptions that
seem to affect
some modules
especially
often.<br
