Hello I have been debugging for one week and it drives me crazy ; I am using the file system library ; I could make it work ok with SD card but now my problem is a usb host
the only diffirent of my board from MCBSTM32C is that power control is GPIOB.15
I have changed that in the code of the MSD_file example and i can control the host power
but the problem that the software always turn back that the device is not connected .
after debugging I noticed that usbh_msc_status(0, 0) always retun false ; I am using 4GB USB flash .
my program is just to create a TXT file inside the usb flash ; I am afraid it is a library bug ; so anyone has this problem before?
Thank you in advanced
Regards Sami
Sami,
I have the very same problem, but with STM32F105. When I use ST's USB stack my board works fine. But when I use Keil's MSC application (V4.50) it fails to connect. Until now I got no response from Keil's support.
Regards,
Paulo
