Hi everyone,

I have some problem with my STM32F105RC board.for USB MSC application.

I can write usb stick perfectly but some usb is problem and I can not write. That's why

USB always busy with something and I take a communication error from my modbus designed. I think, it is always here;

static void BSP_Delay(uint32_t nTime, uint8_t unit)

{

BSP_delay = nTime;

BSP_SetTime(unit);

while(BSP_delay != 0);

TIM_Cmd(TIM2,DISABLE);

}

so can you give me some advice??

#stm32f105rc #usb-msc

You'd have to dig into whether the timer is setup/enabled, and if variables here are volatile. Evaluate what it's using the delay for.

My preference would be to setup the timer to free run, and mark time against the count.
