Don’t know if anyone can help, but every which way I try, I can’t get an SD card mounted (It works fine on another ESP32s3), The adafruit/SdFat - Adafruit Fork @ ^1.5.1 library won’t compile under Platformio using unphone9 as the board… The current adafruit SdFat library compiles fiine, but the SdFat.begin() call fails. Can anyone point me towards a fix ? Regards, Susan ---

Hi Susan! I’m compiling fine in Platformio using Adafruit’s 1.5.1… Have you tried the “everything” library example? E.g.: ```auto ~/unPhoneLibrary/examples/everything $ docker run -it --user 1000:1000 --group-add=dialout --group-add=ubuntu -v /home/hamish/unPhoneLibrary/examples/everything:/home/ubuntu/project -v /tmp/.X11-unix:/tmp/.X11-unix --env DISPLAY --env MAGIC_COM= hamishcunningham/iot:magic entrypoint... $0 = /home/ubuntu/entrypoint.sh $* = PATH = /home/ubuntu/the-internet-of-things/support/tooling/platformio/penv/bin:/opt/qemu/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin MAGIC_COM = pulling latest from git repos... ... working in /home/ubuntu/project running shell (penv) ubuntu@b581c1155c7f:~/project$ pio run -e unphone9 Processing unphone9 (board: unphone9; platform: espressif32 @ ^6.0.1; framework: arduino) ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Verbose mode can be enabled via `-v, --verbose` option CONFIGURATION: https://docs.platformio.org/page/boards/espressif32/unphone9.html PLATFORM: Espressif 32 (6.5.0) > unPhone 9 HARDWARE: ESP32S3 240MHz, 8.31MB RAM, 7.94MB Flash DEBUG: Current (cmsis-dap) External (cmsis-dap, esp-bridge, esp-builtin, esp-prog, iot-bus-jtag, jlink, minimodule, olimex-arm-usb-ocd, olimex-arm-usb-ocd-h, olimex-arm-usb-tiny-h, olimex-jtag-tiny, tumpa) PACKAGES: - framework-arduinoespressif32 @ 3.20014.231204 (2.0.14) - tool-esptoolpy @ 1.40501.0 (4.5.1) - toolchain-riscv32-esp @ 8.4.0+2021r2-patch5 - toolchain-xtensa-esp32s3 @ 8.4.0+2021r2-patch5 Converting sketch.ino LDF: Library Dependency Finder -> https://bit.ly/configure-pio-ldf LDF Modes: Finder ~ chain, Compatibility ~ soft Found 63 compatible libraries Scanning dependencies...

Thanks Hamish. Please correct me if I’m mistaken, bit the “everything” sketch doesn’t seem to use the SD card. Your hardware description suggests that SD\_CS is connected to TCA9555, but that doesn’t seem to match with the schematic. This is making it difficult for me to guess what the SD\_CS pin assignment should be. Set at 43 obviously makes bit 3 high. I’ve tried using other values to toggle the 3 msbs, but this hasn’t resolved the issue. This is all a bit of a shame as it’s currently making the device unsuitable for my intended application. Do you have any plain, simple examples of the SD card being used, perhaps to write a simple file? My code currently runs fine on an alternate S3 board… ---

There’s not much point in having a support forum for a product if nobody provides that support. I purchased an Unphone because It’s a UK based educational endeavour. but when you can get a quicker technical response from China it makes this look like a bad decision. ---

The “everything” sketch displays an image read from the SD card. ---
