[NOT Solved] F407 and SanDisk Cruzer Blade 16GB don't work (32GB work)

I tested 3 pendrives, 4GB (Samsung?), 16GB and 32GB (SanDisk Cruzer Blade).

​

Two worked on the STM32F407VG.

​

SD card adapter also doesn't work, 8GB (Kingston), 2GB (Generic), 16GB (Sandisk Ultra).

​

SanDisk Cruzer Blade 16GB don't work.

​

Using USB host with STM32CubeIDE 1.3 (Version 1.4 does not work with ST-Link V2 :expressionless_face:)

​

​In case anyone has problems with this, I leave it registered that it can be common.

​

All devices run on Windows 10 x64 and Android 10 (Smartphone).

pendrive.txt file is written to your usb disk after flashing code to controller

you have to eject usb disk and plug it to your controller

you wil able to see pendrive.txt file in your usb disk

"The controller was unable to create the file" Thanks

[dbgarasiya]

this is working example

try it with simple pendrive.txt in root folder like

"pendrive.txt"

I was able to configure the debug messages (level 3) and noticed that the SD card only works if the microcontroller boots with the SD card connected. If the microcontroller boots and then connects the SD card, then it doesn't work. But this does not happen with a USB stick. With pendrive, it works in both cases.

If the microcontroller boots with the Pendrive connected:

This problem of not recognizing the SD card after boot, occurs on both ports, HS and FS.

Are you trying to work both usb mass storage device (sd card data shown as drive in computer ) and usb disk (pen drive ) at same time ?

No, I just assembled the code with the two ports to test, I am using only one port at a time to test. I'm testing with an adapter of this type:

The same thing happens with this other adapter model:
