Issue resolved

[Gcare.1]

Could you explain how you resolved your issue? Facing the same problem

[VKUMA.12]

while(1){

MX_USB_HOST_Process();

retUSBH = FATFS_LinkDriver(&USBH_Driver, USBHPath);

HAL_Delay(500);

 if((Appli_state == APPLICATION_DISCONNECT)||(Appli_state == APPLICATION_IDLE))

{ 

lcdprintchar("     ERROR    ",0,50,COLOR_BLACK,COLOR_PURPLE);

lcdprintchar("PLEASE INSERT PENDRIVE....",80,100,COLOR_BLACK,COLOR_PURPLE);

HAL_Delay(5000);

}

if(Appli_state == APPLICATION_START)

{

lcdprintchar("CONNECTED ",100,100,COLOR_BLACK,COLOR_PURPLE);

HAL_Delay(5000);

}

if(f_mount(&USBHFatFS,USBHPath,1)==FR_OK)

{

if(f_open(&USBHFile,"FILE.TXT",FA_READ)==FR_OK)

{

}

f_close(&USBHFile);

HAL_Delay(500);

}

}

This is working code.................

[Tesla DeLorean]

The F407-DISCO board should also have HAL examples related the the "FW Upgrade" method where IAP was demonstrated using a USB Flash Drive.

And there should also be work MSC USB HOST examples for one or more of the F4 EVAL series boards.

[Gcare.1]

Thanks alot,

The code is also working fine for me!
