Hi,all
MPEG2-TS------>CY7c68013------>PC
recently,i am doing a job which mpeg2-Ts stream Transferred to a computer.i used cy7c68013a-56 chip,endpoint2 bulk in 4xbuffer.Frimware,i reference to http://www.cypress.com/?rID=39714
my question is:
When I received the usb pass over the data and stores it into a TS file, i found about 1/3 data lost.
Driver: ezusb.sys
frimware:
CPUCS = 0x10; // CLKSPD[1:0]=10, for 48 MHz operation
SYNCDELAY;
REVCTL=0x03;
IFCONFIG = 0xCB; // IFCLK Source internal (i.e.) Gated MPEG_CLK, MPEG_CLK is connected to SLWR
// FX2LP in SLAVE FIFO Mode
SYNCDELAY;
FIFORESET = 0x80; // activate NAK-ALL to avoid race conditions
SYNCDELAY; // see TRM section 15.14
FIFORESET = 0x82; // reset, FIFO 2
SYNCDELAY; //
FIFORESET = 0x84; // reset, FIFO 4
SYNCDELAY; //
FIFORESET = 0x86; // reset, FIFO 6
SYNCDELAY; //
FIFORESET = 0x88; // reset, FIFO 8
SYNCDELAY; //
FIFORESET = 0x00; // deactivate NAK-ALL
SYNCDELAY;
PINFLAGSAB = 0x00; //
SYNCDELAY;
PINFLAGSCD = 0x00; //
SYNCDELAY;
PORTACFG = 0x00; //
SYNCDELAY;
FIFOPINPOLAR = 0x04; // SLWR is configured as active HIGH : Can be changed to 0x00 for SLWR to be active Low
SYNCDELAY;
EP2CFG = 0xE0; // VALID - 1,DIR - IN,Type- Bulk, Size - 512 Bytes, Quad Buffered
SYNCDELAY;
EP4CFG = 0x00; // clear valid bit
SYNCDELAY; //
EP6CFG = 0x00; // clear valid bit
SYNCDELAY; //
EP8CFG = 0x00; // clear valid bit
SYNCDELAY;
EP2FIFOCFG = 0x08; // AUTO IN, NO Zero Length Packets, 8- bit Wide
SYNCDELAY;
EP2AUTOINLENH = 0x02; // Auto-commit 512-byte packets
SYNCDELAY;
EP2AUTOINLENL = 0x00;
SYNCDELAY;
OEA |= 0x30;
IOA &= ~20;
I beg your reply......

Hello dear
we are trying same thing but couldn't succeed to record TS, we have removed tuner and demodulator from reference design and placed a 8 bit parallel MPEG TS Connector to give it from external tuner.. but facing basic problem to record it.. is there any application available to record TS?
here is detail about our efforts :
We Are recently trying to capture parallel 8 bit Mpeg TS using CY7C68013A-56LTXC and get these MPEG TS to USB port.
for this purpose we have referred design FX2LP_DMB_TH_TV_Dongle and prepared our OWN PCB without Tuner and de-modulator , in our PCB we use to give Parallel TS on CY7C68013A , and using control center fprogramed pre build HEX file of USBTV & MPEG_Free .
after this PC is still not able to capture / record MPEG TS file . even in device tree OUR PCB detected as DMBTV and Cypress FX2lp Streamer Example device .
please suggest corrective action to help us to move out from this situation.
Regards
Satish P.
