 672         * host/apps/test_usrp_standard_tx.cc (main): added -l (loopback) option
 673
 674         * firmware/include/fpga_regs.h (FR_MODE): added new mode register.
 675         * host/lib/usrp_basic.cc (usrp_basic): init to non-loopback mode
 676
 677         * host/apps/test_usrp_standard_tx.cc (main): changed default
 678         interp rate to 16 (=> 32MB/sec).
 679
 680         * host/lib/usrp_bytesex.h (host_to_usrp_short): New.  Conditional
 681         byte swapping between host and usrp.
 682         * host/app/test_usrp0.cc: added conditional byte swapping.

 684
 685 2004-07-30  Eric Blossom  <eb@comsec.com>
 686
 687         * host/swig/Makefile.am: now installs usrp_prims.* directly in site-packages.
 688         One could argue that this isn't particularly pretty, but it does
 689         get it into the namespace where we want it.
 690
 691 2004-07-29  Eric Blossom  <eb@comsec.com>
 692
 693         * host/apps/test_usrp0.cc (main): added code to set tx frequency.
 694
 695 2004-07-12  Eric Blossom  <eb@comsec.com>
 696

 699 2004-07-11  Eric Blossom  <eb@comsec.com>
 700
 701         * host/lib/usrp_basic.cc: invert TX_SYNC
 702
 703         * host/lib/usrp_basic.{h,cc},usrp_standard.cc: now temporarily
 704         disable tx and rx paths when changing interpolation or decimation
 705         rate.  Didn't fix the problem, but shouldn't hurt either.
 706
 707 2004-07-07  Eric Blossom  <eb@comsec.com>
 708
 709         * firmware/src/common/_startup.a51 (__sdcc_external_startup):
 710         Rewritten to avoid fragile kludge.  Now requires that all firmware
 711         be compiled with --no-xinit-opt.
 712
 713         * firmware/src/usrp{0,1}/Makefile.am: pass in linker option to
 714         place usb descriptors at 0xE000 absolute.  This works around the
 715         fact that the assembler and linker don't really implement the
 716         .even directive.
 717         * firmware/src/usrp{0,1}/usb_descriptors.a51: now place
 718         descriptors in USBDESCSEG, which we force to 0xE000.
 719
 720         * firmware/src/usrp1/board_specific.c (power_down_9862s):
 721         Power down the 9862's when the firmware is loaded to keep from
 722         burning up the board.  Note to Analog Devices: put a power pad
 723         on these or some other way to get the heat out of them.
 724
 725         * host/lib/usrp_prims.cc (_usrp_load_fpga): Since loading the FPGA
 726         wiggles the shared reset line with the 9862s, we now once again
 727         power down the 9862's.
 728
 729 2004-07-06  Eric Blossom  <eb@comsec.com>
 730
 731         * firmware/src/common/_startup.a51 (__sdcc_external_startup):
 732         picked up bug fixes from 2.4.0 release, and added a fragile kludge
 733         that ensures that our variables are all initialized properly.
 734
 735         * firmware/src/usrp0/usrp_main.c, firmware/src/usrp1/usrp_main.c,
 736         firmware/src/common/usb_common.c: removed deprecated use of
 737         pragma NOIV.
 738
 739 2004-07-05  Eric Blossom  <eb@comsec.com>
 740
 741         * host/lib/fusb_linux.cc (alloc_urb): removed
 742         USBDEVFS_URB_QUEUE_BULK flag.
 743
 744 2004-07-02  Eric Blossom  <eb@comsec.com>
 745
 746         * host/lib/usrp_basic.h: added adc_freq and dac_freq
 747         to disambiguate the interpretation of interpolation and decimation
 748         ratios.
 749
 750 2004-07-01  Eric Blossom  <eb@comsec.com>
 751
 752         * host/swig/prims.i: renamed from usrp_prims.i  Module is now
 753         installed as usrp.prims
 754         * host/lib/usrp_basic.cc (usrp_basic_tx, usrp_basic_rx): power
 755         down 9862 tx or rx path in destructor.
 756         * host/lib/usrp_standard.cc: now control coarse and fine
 757         modulators transparently, based on user provided center freq.
 758         * fpga/sdr_lib/gen_cordic_consts.py: new. generate magic constants for cordic.
 759         * fpga/sdr_lib/cordic.v: `define constants.  integer c00 = <foo>
 760         wasn't being synthesized correctly by Quartus II 4.0
 761
 762 2004-05-28  Eric Blossom  <eb@comsec.com>
 763
 764         * host/lib/usrp_standard.{h,cc}: Now uses 4x interpolator and
 765         9862 cordic.  Tx path looks great up to +/- 44 MHz!
 766         This code still twiddles the coarse modulator manually.
 767
 768 2004-05-27  Eric Blossom  <eb@comsec.com>
 769
 770         * Tagged everything with BEFORE_CLOCK_REVAMP_2004_05_27.
 771         We're about to rework the boards, host code and the verilog to
 772         directly feed the 64 MHz oscillator to the 9862's and the FPGA.
 773         With any luck, life will drastically improve...
 774
 775
 776 2004-05-25  Eric Blossom  <eb@comsec.com>
 777
 778         * host/lib/usrp_standard.{h,cc} (class usrp_standard_tx_use_nco):
 779         new.  Class that utilizes the AD9862's built-in NCO for up conversion.

 803
 804         * host/lib/usrp_standard.cc (make): changed constructors and make
 805         to pass the interp/decim rate.  This ensures that the rate is set
 806         to something the user wants when the rx and tx paths are first
 807         enabled.
 808
 809         * host/lib/usrp_basic.cc (initialize): enabled xrun status polling.
 810         (set_fpga_rx_sample_rate_divisor,set_fpga_rx_sample_rate_divisor):
 811         set FPGA register to N-1.
 812
 813         * host/lib/usrp_standard.cc (set_interp_rate, set_decim_rate): now

 823         * firmware/src/usrp1/spi.c (spi_write,spi_read): clock once w/o
 824         enables for the FPGA's benefit.  We're also clocking one extra
 825         cycle at the end with enables again for the FPGA.  I think we
 826         should remove the extra clocking at the end.
 827
 828 2004-04-17  Eric Blossom  <eb@comsec.com>

 893         builds from the top along with the host code.
 894
 895         * I've touched just about every file in the tree, both
 896         firmware and host side.  The combo is now working well.  It is
 897         capable of half duplex reading or writing at 31.25 MB/sec and
 898         (pseudo) full duplex reading and writing at 15.625 MS/sec in each
 899         direction.
 900
 901         In addition, the receive side is decoupled from the transmit side

 930         use reverse_iterator to cancel pending requests from the back to
 931         the front.  This removes the mystery of more than one cancelled
 932         urb having a non-zero transfer count.
 933
 934         * host/lib/test_fusb.cc (test_output): fixed defective test case
 935         that was having me think the tx code wasn't working.
 936

 938
 939         * host/lib/fusb.{h,cc}:  work in progress on the Rx path.

 962         FPGA clear_status line to the previous location of SDO.  This
 963         means that firmware from here out will only work with the latest
 964         FPGA bitstreams that have this pin configurd as an input.
 965
 966         * host/lib/fusb.{h,cc}: fast streaming usb library built on top of libusb.

1022
1023         * firmware/basic_fw/src/usrp_commands.h: removed obsolete
1024         foo_CLR_bar commands.  Added UCMD_SET_GSTATE_OUTPUT_ENABLE to
1025         enable the output of the GPIF state on the low 3 bits of Port E.
1026
1027         * host/usrper/usrper.cc (usrper_load_firmware): now implements
1028         "load_firmware" command.

1031
1032         * host/usrper/usrper.cc (usrper_load_fpga),
1033         firmware/basic_fw/src/fpga.c: changed load_fpga to expect a byte
1034         count, not a bit count in the xfer packet.
1035
1036         * firmware/basic_fw/src/fpga.c (do_fpga_config_start): cleanup,
1037         add appropriate delay.

1042
1043         * firmware/basic_fw/include/fx2regs.h: changed sfr and sbit syntax
1044         to match what SDCC expects.  Now the SFR's are really allocated
1045         where they are supposed to be ;-)
