ESP32 with spiram larger than 4MB fails

[MaBecker]

E (552) spiram: Expected 4096KiB chip but found 8192KiB chip. Bailing out..

looks like the size is fixed in sdkconfig

gw@sparky:~/workspace/Espruino$ grep "chip but found" -R .
grep: ./app/build/esp32/libesp32.a: binary file matches

Looks like it's internal :( Although am I right in thinking that libesp32.a actually gets built and put in EspruinoBuildTools, so it might be fixable?

Is this helpful? https://esp32.com/viewtopic.php?t=10666

Please try setting PSRAM type to "auto-detect" in menuconfig: https://docs.espressif.com/projects/esp ... piram-type

I don't have a way to test here

[MaBecker]

yes it's possible:

will build new sdk files and give it a try

[MaBecker]

diff sdkconfig sdkconfig.old

< CONFIG_SPIRAM_TYPE_AUTO=y              <-------

[MaBecker]

And it works :-)

[gfwilliams]

Excellent - thanks! Please could you upload the new build to https://github.com/espruino/EspruinoBuildTools ?

You did the build last time so I think you'd be less likely to break things than me ;)

[MaBecker]

just updated the build tools for esp32.
