Hello, Writing a an USB smartcard driver, I choose to start a new thread instead of continue the last thread i ve initiated. I have written the configuration for the LPC2368. Here the configuration:
const BYTE USB_ConfigDescriptor[] = { /* Configuration 1 */ USB_CONFIGUARTION_DESC_SIZE, /* bDescriptorType */ USB_CONFIGURATION_DESCRIPTOR_TYPE, /* bDescriptorType */ WBVAL( /* wTotalLength */ USB_CONFIGUARTION_DESC_SIZE + USB_INTERFACE_DESC_SIZE + SMARTCARD_CLASS_DESC_SIZE + 3*USB_ENDPOINT_DESC_SIZE ), 0x01, /* bNumInterfaces */ 0x01, /* bConfigurationValue */ 0x03, /* iConfiguration */ /*USB_CONFIG_BUS_POWERED */ /* bmAttributes */ 0x80, USB_CONFIG_POWER_MA(100), /* bMaxPower */ /* Interface 0, Alternate Setting 0, HID Class */ USB_INTERFACE_DESC_SIZE, /* bLength */ USB_INTERFACE_DESCRIPTOR_TYPE, /* bDescriptorType */ 0x00, /* bInterfaceNumber */ 0x00, /* bAlternateSetting */ 0x03, /* bNumEndpoints */ 0x0b, /* bInterfaceClass */ //USB_DEVICE_CLASS_HUMAN_INTERFACE, /* bInterfaceClass */ 0x00, /* bInterfaceSubClass */ 0x00, /* bInterfaceProtocol */ 0x00, /* iInterface */ /* Smartcard Class Descriptor */ SMARTCARD_CLASS_DESC_SIZE, /* bLength */ SMARTCARD_SMARTCARD_DESCRIPTOR_TYPE, /* bDescriptorType */ WBVAL(0x0100), /* 1.00 */ /* bcdCCID */ 0x00, /* bMaxSlotIndex */ 0x07, /* bVoltageSupport: 5v, 3v and 1.8v */ 0x03,0x00,0x00,0x00, // dwProtocols: supports T=0 and T=1 0xF8,0x34,0x00,0x00, // dwDefaultClock: 13,56 Mhz (0x00000FA0) 0xF8,0x34,0x00,0x00, // dwMaximumClock: 13,56 Mhz (0x00000FA0) 0x00, // bNumClockSupported => no manual setting 0x00,0x2A,0x00,0x00, // dwDataRate: 10752 bps (0x00002A00) 0x08,0xF8,0x01,0x00, // dwMaxDataRate: 129032 bps (0x0001F808) 0x00, // bNumDataRatesSupported => no manual setting 0xFE,0x00,0x00,0x00, /* IFSD */ 0x00,0x00,0x00,0x00, /* Synchron Protocol */ 0x00,0x00,0x00,0x00, /* Mechanical Features, DWORD */ (0x04 | 0x08 | 0x10 | 0x40 | 0x02),(0x01 | 0x02),0x02,0x00, /* Features - Automatic activation - clk, baud rate, voltage :automatic - short APDU level exchange*/ // CCID can set ICC in clock stop mode - Automatic IFSD exchange(for T=1) 0x0F,0x01,0x00,0x00, /* Max CCID Message Length : Maximun block size + header (261 + 10)*/ 0xFF, /* Class Get Response */ 0XFF, /* Class enveloppe */ 0x00,0x00, /* wLayout */ 0x00, /* Pin Support */ 0x01, /* Max CCID Busy Slots */ /* Endpoint, INTERRUPT In */ USB_ENDPOINT_DESC_SIZE, /* bLength */ USB_ENDPOINT_DESCRIPTOR_TYPE, /* bDescriptorType */ 0x81, /* bEndpointAddress */ USB_ENDPOINT_TYPE_INTERRUPT, /* bmAttributes */ WBVAL(0x0008), /* wMaxPacketSize */ 0x18, /* 32ms */ /* bInterval */ /* Endpoint, SMART CARD Bulk In */ USB_ENDPOINT_DESC_SIZE, /* bLength */ USB_ENDPOINT_DESCRIPTOR_TYPE, /* bDescriptorType */ 0x82, /* bEndpointAddress */ USB_ENDPOINT_TYPE_BULK, /* bmAttributes */ WBVAL(0x0040), /* wMaxPacketSize */ 0x00, /* 32ms */ /* bInterval */ /* Endpoint, SMART CARD BULK Out (from the host to the device) */ USB_ENDPOINT_DESC_SIZE, /* bLength */ USB_ENDPOINT_DESCRIPTOR_TYPE, /* bDescriptorType */ 0x02, /* bEndpointAddress */ USB_ENDPOINT_TYPE_BULK, /* bmAttributes */ WBVAL(0x0040), /* wMaxPacketSize */ 0x00, /* 32ms */ /* bInterval */ /* Terminator */ 0 /* bLength */ };
The endpoints seem to be well configured since I can write {50, 03, 00, 00} on the Interrupt EP IN :
BYTE smcSlotStatusChange (void) { BYTE msg[4]; msg[0] = RDR_to_PC_NotifySlotChange; //bMessageType : 50 msg[1] = 0x03; //bmSlotICCstate 00000011 - slot 0 status changed and slot 0 current state is ICC present (manual that I linked page 56) EP1DataSnd.pData = msg; EP1DataSnd.Count = 4; USB_DataInStage1(); //write to the EP IN 0x81 return 0; }
The host respond successfully with the telegram {63, 00, 00, 00, 00, 00, 01, 00, 00, 00} (PC_to_RDR_ICCPowerOff).
Then I successfully sended the RDR_to_PC_Slotstatus in the Bulk IN (0x82) {81, 00, 00, 00, 00, 00, 01, 01, 00, 01}
The host respond successfully with the telegram {62, 00, 00, 00, 00, 00, 02, 00, 00, 00} (PC_to_RDR_ICCPowerON).
THEN I TRIED TO SEND A RDR_to_PC_Datablock but the host doesn't catch it! I tried with the telegramms: BYTE FirstDataBlock[14] = {0x80, 0x00, 0x00, 0x00, 0x00, 0x00, 0xXX, 0x40, 0xFE, 0x00}; // BYTE FirstDataBlock[14] = {0x80, 0x04, 0x00, 0x00, 0x00, 0xXX, 0xFF, 0x40, 0xFE, 0x00, 0x03, 0x00, 0x00,0x00};
where 0xXX ist the last BULK-OUT received bSeq BYTE but the Host does'nt take it! I can't see it on the USBLYzer!
Has anybody an Idea about it?
Here the protocol functions:
void smcDispatchMessage() { BYTE ErrorCode; //Initialize the pointers UsbMessageBuffer = EP2DataRcv.pData; UsbInMessageBuffer = EP2DataRcv.pData; switch (*UsbMessageBuffer) { case PC_to_RDR_IccPowerOn: //0x62 ErrorCode = PC_to_RDR_IccPowerON(); smcDataBlock(ErrorCode, FirstDataBlock); break; case PC_to_RDR_IccPowerOff: //0x63 ErrorCode = PC_to_RDR_IccPowerOFF(); smcSlotStatus(ErrorCode, IccPowerON); break; } } Thanks in advance!
