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
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.
