]]> Tue, 07 May 2013 11:41:22 -0600 AN4067 - Endpoint FIFO Architecture of EZ-USB FX1/FX2LP™ http://www.cypress.com/?rID=12926 This application note describes the FIFO architecture of the EZ-USB FX1, the full speed USB microcontroller and the EZ-USB FX2LP„·, the high-speed USB microcontroller. The purpose of this application note is to help the user understand the very basics of the FX1/FX2LP and get familiar with the terminologies used while describing the data flow in FX1/FX2LP. The application note addresses and discusses the following:

  • Three modes of operation of the FX1/FX2LP
  • Endpoint Configuration and Multiple Buffering
  • Three Domains that form the basic component of the FIFO architecture
  • Arming and committing endpoint buffers
  • Endpoint operation in manual vs. auto mode
]]> Thu, 02 May 2013 05:30:16 -0600 Difference between FX2LP™ Port I/O, GPIF, and Slave FIFO Modes - KBA83522 http://www.cypress.com/?rID=79305 Answer: The key difference is that in the Port I/O mode, devices can use the FX2LP CPU to process USB data directly, without the need of a Master control. The GPIF interface is the master when you use the GPIF mode, and the Slave FIFO mode requires an external master, such as an FPGA.


FX2LP was designed to be used in either one of the modes: Port I/O, Slave FIFO, or GPIF. For more information, refer to the application note Endpoint FIFO Architecture of EZ-USB FX1/FX2(TM) - AN4067.


It is possible to switch from one mode to another. Before switching from slave FIFO to GPIF or vice versa, you must make sure that there is no data transfer in progress as far as the physical interface is concerned or for that master on the USB end (host is not sending or receiving data from any of the endpoint).


You must make sure that the FIFO is reset and the device is in a state (no data activity in progress). When this is done, you may switch from one mode to the other. Switching from one mode of operation to another is not an intended feature, but something that you may do as long as the device is in a stable state.

]]> Thu, 02 May 2013 05:24:30 -0600 Read and Write to EZ-USB® Internal Memory (AN21xx/FX/FX1/FX2/FX2LP™) - KBA87109 http://www.cypress.com/?rID=79304 Answer: You can use the A0 vendor command to read and write to the internal memory of EZ-USB (AN21xx/FX/FX1/FX2/FX2LP). For this vendor command to work, the CPU of the device must be in reset. To put the CPU in reset, send the A0 vendor command with E600 (for FX1/FX2/FX2LP; for older parts like FX use 7F92) as value and 01 as data. To bring the CPU out of reset, send 00 as data.


For reading and writing to the external memory you can download vend_ax example to the device, and then use the A3 vendor command. Both these vendor commands use Value field to specify the memory location.


Note Install CY3684 FX2LP and CY3681 FX2 development kits for a different version of vend_ax (file path:C:\Cypress\USB\Examples).

]]> Fri, 22 Mar 2013 05:26:02 -0600 Startup I2C Clock Rate for EZ-USB® FX2LP™ - KBA85384 http://www.cypress.com/?rID=34580 Answer: The bus frequency defaults to approximately 100 kHz for compatibility, but you can configure it to run at 400 kHz for devices that support the higher speed. Setting bit 0 of I2CTL (E67A) register to 1 causes EZ-USB to drive SCL at approximately 400 kHz. When the CPU begins to run, firmware can modify the I2CTL.0 bit.

]]> Fri, 22 Mar 2013 00:45:08 -0600 I2C Read using FX2™ and FX2LP™ - KBA85382 http://www.cypress.com/?rID=40050 Answer: I2C read implementation is illustrated in the file i2c.c, which is available in the path \Cypress\USB\Target\Lib\LP\i2c.c.

In this file, the implementation of read occurs in the ISR. The I2C_Read function sends the Read Command and changes the I2C.PktStatus to I2C_PRIME. The I2C enters the ISR every time a byte of data is successfully transferred when the DONE bit is set High.

When the following section of code is executed for the first time, the data that has been read is stored to I2CPckt.dat and the status is changed to I2C_RECEIVING:

case I2C_PRIME:
I2CPckt.dat[I2CPckt.count] = I2DAT;
I2CPckt.status = I2C_RECEIVING;
if(I2CPckt.length == 1) // may be only one byte read
I2CS |= bmLASTRD;
break;

To read more data, the following section of the code is executed the next time the ISR is serviced:

case I2C_RECEIVING:
if(I2CPckt.count == I2CPckt.length - 2)
I2CS |= bmLASTRD;
if(I2CPckt.count == I2CPckt.length - 1)
{
I2CS |= bmSTOP;
I2CPckt.status = I2C_IDLE;
}
I2CPckt.dat[I2CPckt.count] = I2DAT;
++I2CPckt.count;
break;

To avoid this error, follow these steps:

  1. In the µVision2 Editor, click ‘Options for Target’ and then select the ‘Output’ Tab. Ensure that the following path is described in the ‘ Run User Program #1’:

     

    ..\..\..\Bin\hex2bix -i -f 0xC2 -o fw.iic fw.hex

  2. If at power-on-reset, the EZ-USB detects an EEPROM connected to its I2C with the value 0xC2 at address zero, the EZ-USB loads the firmware in EEPROM into an on-chip RAM. It also sets the RENUM bit to ‘1’, causing standard device requests to be handled by the firmware instead of the default USB device.

]]> Thu, 20 Dec 2012 02:45:23 -0600 Utilization of the Unused GPIF Control Lines - KBA83964 http://www.cypress.com/?rID=38449 Answer: No, triggering of the GPIF does not change the state of the unused control lines. This is an advantage in a situation when we are using only a few of the GPIF control lines. Let us say, of the 6 available control lines, we are using only 2 for GPIF and the rest 4 can be used for other purposes. When the GPIF is idle, we can manipulate (enable and drive a value) the state of the unused 4 control lines using the GPIFIDLECTL register. Even when the GPIF is triggered, the unused control lines will retain the value they were initialized to in the GPIFIDLECTL register.

]]> Thu, 20 Dec 2012 02:38:31 -0600 FX2LP does not enumerate for Firmware (code+xdata) of Size Greater than 16 K - KBA83973 http://www.cypress.com/?rID=39838 Answer: Check in your .m51 file where the compiler is placing the descriptor files. The issue might be that the compiler is putting the descriptor table into external memory. When this happens fw.c relocates the descriptor table to memory location 0x0080 where it overwrites some portion of the code. This might cause error in enumeration or incorrect functioning of some part of code. You can specify the starting location of your code memory after leaving space for the interrupt vector tables and the descriptor table.


For example, in the BL51 locate tab, you can specify your code to begin at a location greater than (0x0080 + length of your descriptor table).

Overview

AN70486 describes a host application built on the Microsoft Visual C++ 2008 platform that uses CyUSB.dll to communicate with Cypress USB driver, CyUSB.sys. The host application communicates with the BULK IN and BULK OUT endpoints of FX2LP, using the interfaces provided by the APIs of CyUSB.dll. The CyUSB.dll in-turn communicates internally with Cypress USB driver (CyUSB.sys), for talking to these endpoints. This host application implements the transfer only with devices that pass the particular VID/PID identification. The example device used in this application note is the Bulkloop device. The firmware that is attached along with this application note causes a loop back of data inside the device. Thus this host application, with the attached Bulkloop device, demonstrates the loopback of data.

The thermal via is used for the thermal design consideration of FX2/FX2LP 56-pin QFN package part. The design of the land area for the exposed paddle is critical to proper thermal transfer. A copper fill is to be designed into the PCB and under the QFN package in order to assist thermal transfer. The heat is transferred to the solid signal ground plane of the board over these vias.

You can diminish the number of vias for better routing the trace of other signal layers, but it will affect the performance of thermal efficiency. Normally we use a 5×5 array of 25 thermal vias in the exposed paddle. We recommend that there should have to be at least 4×4 array of 16 thermal vias in the exposed pad.

FAQs

Question 1: I get the following error while binding my device to CyUSB.sys in Windows 7/Vista 64-bit environment, “Windows encountered a problem installing the driver software for your device” or usage of CyUSB.sys in Vista 64-bit operating system gives Code 39 error (Code 52 in the case of Windows 7). What do these errors mean? How can they be resolved?

Answer: CyUSB.sys downloaded through our website is an unsigned driver. This error reported while an unsigned driver used in 64-bit operating systems in normal mode. Following are the steps to disable driver signature enforcement in 64-bit operating system:

a) During boot-up press F8.

b) In the list of options that appear select “Disable driver signature enforcement”.

This should resolve the issues.

Note: In the case of Windows Vista 64-bit operating system the error message is “Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)”. In the case of Windows 7 64-bit operating system it is "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)".

Question 2: What is the signing procedure when script files are used?

Answer:When script files are used, the Inf file should contain both VID/PID combinations while signing the driver. The procedure for signing the procedure is the same as that for regular drivers. The script file (.spt file) will need to be shipped along with the Inf/Sys files.

]]> Mon, 30 Apr 2012 04:04:39 -0600 SX2's response to SET_INTERFACE request http://www.cypress.com/?rID=50762  

SET_INTERFACE is a standard EP0 request with no data phase. Though SET_INTERFACE is a standard EP0 request it needs to be handled by external master to perform all the changes in Endpoint configuration. So SX2 notifies the external master with the SETUP interrupt.
    
In case of other non-standard EP0 requests with no data stage, external master is notified with the SETUP interrupt, and the external master can accept the packet and complete the handshake phase by writing zero to the byte count register. SX2 waits for the external master to write zero into byte count register before acknowledging it.
 
But unlike the case of non-standard EP0 requests with no data phase, SX2 doesn't wait for external master to write zero into byte count register in the case of SET_INTERFACE. Instead SX2 acknowledges the transfer by itself.    
 
As per the USB protocol, standard EP0 Device requests without a data stage must be completed in 50ms. If it is not responded to within 50ms, the host will reset the device. To avoid this, SX2 is made to 'ACK' the SET_INTERFACE by itself, without waiting for the external master to write zero into the byte count register.
 
So, if the SET_INTERFACE request is followed by another EP0 request, unless the firmware is fast enough to read the SETUP packet of SET_INTERFACE before the host writes into register,0x32, with the SETUP PACKET of the next command, the commands will get mixed up. Either by making firmware fast enough to read the first setup packet before the arrival of the next setup packet, or having the host issue the second command after the first command has been attended to, can help you to read both the setup packets, without mixing them up.
