1 year ago For seeeduino xiao issue, please post it to their support forum/repo. Here we should focus on the qt py m0. Could you
- Which SDcard reader you are using
- Upload the picture of your hardware setup with the sdcard reader to make sure the wiring and pin config is correct.
- did you make any modification to the msc_sdfat example, if yes then please attach the modified sketch
- please attached the compiled output log of arduino IDE for analysis.

What happened ?
Hi, I have a QT py m0 (atsamd21e18a) board. I can run msc_ramdisk tinyusb version 1.17.0 on it. It works perfectly for me. Before that, I could run msc_sdfat (16Gb) on a seeeduino xiao (atsamd21g18a) on tinyusb version 0.10.5 ( I found on the internet that tinyusb version 0.10.5 only will work on seeeduino Xiao). but the problem is that I want to run msc_sdfat on QT py m0 (atsamd21e18a), the code compiles perfectly, and I upload it on the device. But the storage is not opening and OS shows this "please insert a disk into a removable device." I checked the connection sd card reader to QT py m0 by running this example program SD -> ReadWrite, and it works. But I checked it by Sdfat-adafruit fork -> open-next it doesn't work. Another point is I test QT py m0 by example program tinyusb msc_sd, the removable device opened, and I can open my files on it. But all options are not working. For instance, I can't copy a file into it. All examples tinyusb msc work perfectly on seeeduino xiao (tinyusb version 0.10.5) but do not work on QT py m0 (tinyusb version 1.17.0). last point, tinyusb version 0.10.5 doesn't compile on QT py m0.
