I'll do a new build this afternoon.<br>
<br>
It's really nice we're getting more RAM on the fly.<br>
<br>
Btw, we will need a separate build config once they also fix the
PSRAM bug on the core. The workaround eats some performance (not
too much, but still).<br>

<div>We previously used a hard-coded selection of "ESP-PSRAM32

modules we are now using (as Espressif have discontinued the
4MB versions). Those new modules have 8MB PSRAM and are
"ESP-PSRAM64 or LY68L6400”. The auto-detect setting seems to
work well, and can detect and support the installed PSRAM
automatically.</div>

<div>I have built an edge release based on this, and will leave
for 24 hours. If ok, I will then move that to EAP and to MAIN
at the weekend. This will be 3.2.008. We need to get this out
ASAP, as recipients of the new modules may do an OTA update
and have issues (so far only 1, and he recovered using
esptool).</div>

<div>@Michael: I suggest you follow with your server. Let me
know the path to your new update (from SPIRAM branch) and I
will test on the ESP32-WROVER-B 8MB module I have here.</div>

Our latest wifi-only modules are coming with
ESP-WROVER-B module, and that includes 8MB PSRAM/SPIRAM
(not 4MB, our standard so far). I have had one report
from the field that factory firmware 3.2.002 works fine,
but 3.2.005 crashes on boot with an error:

<div class="">Not sure when that appeared, but I guess
between 3.2.002 and 3.2.005.</div>

<div class="">The user experiencing this problem is
