    Botofan Calin managed to load a huge set of apps https://github.com/botofancalin/M5Stack-MultiApp-Advanced and in an earlier version I could get the sd-updater to work with his app even though he's shrunk the spiffs to its mininum
    actually the spiffs region only needs 380k free for the loader to work

    @grooves38
    yeah, I saw that as well, and tried it
    looks also very nice, but the apps are all embedded, not loaded from SD
    so you are limited by internal flash
    your approach is better I think
    tobozo
    @tobozo
    it should be in the ESP bootloader
    like the gamebuino
    grooves38
    @grooves38
    but sure, to load his app via your loader would be great as well
    I see
    but I guess EsspressIF woN#t support that
    won't

    @tobozo
    i've seen a modified esp8266sdk that does that
    grooves38
    @grooves38
    their focus is to support dual images
    from bootloader
    to have OTA support
    and they want to keep the bootloader generic, more or less
    tobozo
    @tobozo
    i've found the most elegant approach is the one from the odroid-go

    hey cool, chess works now as well

    @tobozo
    in the psram ^^
    grooves38
    @grooves38
    yeah, but not every board has psram
    most of them don't have
    ok, guy, I have to go
    tobozo
    @tobozo
    and not every board with psram has working psram poke @jsdungeon

    thanks again for you help
    :-)
    have a nice evening
    see u

    Hi all, how difficult would it be for me as a coding noob to create an app on the M5 which is recognizing a sudden fall and sends out an e-mail if not picked up after 2 minutes? Something like the apple watch 4 is doing now.
    tobozo
    @tobozo
    there's this M5-Crackscreen app you can use as a start https://github.com/nomolk/M5Stack_CrackScreen
    but it's a long way to distinguish shakes from real falls
    Ulrich Rosenbaum
    @jsdungeon
    Thank you. I thought there might be a way to measure the speed during the fall to get an idea about the nature of the movement.
    I would like to have a fall detector for the elderly as result.

    om nom nom nom https://www.hackster.io/arundale/sqlite3-library-for-esp32-arduino-core-a76ad1
    requires a SD Card of course ^_^

    @tobozo - Too bad ... would be nice to use it on Mongoose-OS together with some bigger Flash. Who needs GB of data on an ESP32? And it's a pity it is always connected to the Arduino Framework ... :flushed:
    tobozo
    @tobozo
    you mean memory-wise ?
    there's still the m$ version though https://github.com/Azure/iot-edge-sqlite
    Manfred Müller-Späth
    @mamuesp
    No, storage flash. I use the ODROID-GO as my favorite prototyping device (don’t need much pins as I use mainly SPI and I2C with GPIO extenders and an interrupt pin), so it has 16MB flash - that would be enough for some nice scenarios, no SD-Card needed there ...
    tobozo
    @tobozo
    What scenario on the ESP32 could possibly use gigabytes of SQLite data ?
    not a web server since filesystem access is enough
    Manfred Müller-Späth
    @mamuesp
    I don’t know - so that’s the question why the SQLite lib is only using an SD-Card. But I think it’s because of the Arduino awareness … addtional filesystems are not very well known there in conjunction with „normal“ flash chips, so the obvious is used ...

    @tobozo
    maybe for someone porting code logic from another language onto an IoT, for database reimport purpose ?
    when I played with the video format for m5stack I was surprised how fast the file seek was, it was much faster than opening a bunch of files with the same weight
