usb control read

I have written a dfu driver for the str711 device, all works ok except control read transfers (OUT transfers).

I have traced the problem down to the usb interrupt routine (CTR_ISR) - This function below checks for a setup packet but the mask will also catch all RX (OUT) transfers including non SETUP ones. In other words the Out0_Process will never get called.

if((wEPVal & (EP_CTR_RX|EP_SETUP)) != 0)

{

_ClearEP_CTR_RX(ENDP0); /* SETUP bit kept frozen while CTR_RX = 1 */

Setup0_Process();

}

else if((wEPVal & EP_CTR_RX) != 0)

{

_ClearEP_CTR_RX(ENDP0);

Out0_Process();

}

changing to

if((wEPVal & (EP_SETUP)) != 0) fixes the problem, is this correct ?

Hi Sjo,

Sorry for the delay...

We have already checked the USB software libray and some mistakes are alredy verified(The new version is not published yet).

Concerning the Out0_Process section we use the following condition .

if((wEPVal &EP_SETUP) != 0)

{

_ClearEP_CTR_RX(ENDP0); /* SETUP bit kept frozen while CTR_RX = 1 */

Setup0_Process();

}

else if((wEPVal & EP_CTR_RX) != 0)

{

_ClearEP_CTR_RX(ENDP0);

Out0_Process();

}

With best regards,

Hich :o

You inform us that you have a new version of the usb library.

Could you publish it ? even if it's unsupported, because we use the current library that have some problem...

Sincerely

Chris.
