 673
 674 2004-07-30  Eric Blossom  <eb@comsec.com>
 675
 676         * host/swig/Makefile.am: now installs usrp_prims.* directly in site-packages.
 677         One could argue that this isn't particularly pretty, but it does
 678         get it into the namespace where we want it.
 679
 680 2004-07-29  Eric Blossom  <eb@comsec.com>
 681
 682         * host/apps/test_usrp0.cc (main): added code to set tx frequency.

 693         disable tx and rx paths when changing interpolation or decimation
 694         rate.  Didn't fix the problem, but shouldn't hurt either.
 695
 696 2004-07-07  Eric Blossom  <eb@comsec.com>
 697
 698         * firmware/src/common/_startup.a51 (__sdcc_external_startup):

 700         be compiled with --no-xinit-opt.
 701
 702         * firmware/src/usrp{0,1}/Makefile.am: pass in linker option to
 703         place usb descriptors at 0xE000 absolute.  This works around the
 704         fact that the assembler and linker don't really implement the
 705         .even directive.
 706         * firmware/src/usrp{0,1}/usb_descriptors.a51: now place
 707         descriptors in USBDESCSEG, which we force to 0xE000.
 708
 709         * firmware/src/usrp1/board_specific.c (power_down_9862s):
 710         Power down the 9862's when the firmware is loaded to keep from
 711         burning up the board.  Note to Analog Devices: put a power pad
 712         on these or some other way to get the heat out of them.
 713
 714         * host/lib/usrp_prims.cc (_usrp_load_fpga): Since loading the FPGA
 715         wiggles the shared reset line with the 9862s, we now once again
 716         power down the 9862's.
 717
 718 2004-07-06  Eric Blossom  <eb@comsec.com>
 719
 720         * firmware/src/common/_startup.a51 (__sdcc_external_startup):
 721         picked up bug fixes from 2.4.0 release, and added a fragile kludge
 722         that ensures that our variables are all initialized properly.
 723
 724         * firmware/src/usrp0/usrp_main.c, firmware/src/usrp1/usrp_main.c,
 725         firmware/src/common/usb_common.c: removed deprecated use of
 726         pragma NOIV.
 727
 728 2004-07-05  Eric Blossom  <eb@comsec.com>
 729
 730         * host/lib/fusb_linux.cc (alloc_urb): removed
 731         USBDEVFS_URB_QUEUE_BULK flag.

 734
 735         * host/lib/usrp_basic.h: added adc_freq and dac_freq
 736         to disambiguate the interpretation of interpolation and decimation
 737         ratios.
 738
 739 2004-07-01  Eric Blossom  <eb@comsec.com>
 740
 741         * host/swig/prims.i: renamed from usrp_prims.i  Module is now
 742         installed as usrp.prims
 743         * host/lib/usrp_basic.cc (usrp_basic_tx, usrp_basic_rx): power
 744         down 9862 tx or rx path in destructor.
 745         * host/lib/usrp_standard.cc: now control coarse and fine
 746         modulators transparently, based on user provided center freq.
 747         * fpga/sdr_lib/gen_cordic_consts.py: new. generate magic constants for cordic.
 748         * fpga/sdr_lib/cordic.v: `define constants.  integer c00 = <foo>
 749         wasn't being synthesized correctly by Quartus II 4.0
 750
 751 2004-05-28  Eric Blossom  <eb@comsec.com>
 752
 753         * host/lib/usrp_standard.{h,cc}: Now uses 4x interpolator and
 754         9862 cordic.  Tx path looks great up to +/- 44 MHz!
 755         This code still twiddles the coarse modulator manually.
 756
 757 2004-05-27  Eric Blossom  <eb@comsec.com>
 758
 759         * Tagged everything with BEFORE_CLOCK_REVAMP_2004_05_27.
 760         We're about to rework the boards, host code and the verilog to
 761         directly feed the 64 MHz oscillator to the 9862's and the FPGA.
 762         With any luck, life will drastically improve...
 763
 764
 765 2004-05-25  Eric Blossom  <eb@comsec.com>
 766
 767         * host/lib/usrp_standard.{h,cc} (class usrp_standard_tx_use_nco):
 768         new.  Class that utilizes the AD9862's built-in NCO for up conversion.

 792
 793         * host/lib/usrp_standard.cc (make): changed constructors and make
 794         to pass the interp/decim rate.  This ensures that the rate is set
 795         to something the user wants when the rx and tx paths are first
 796         enabled.
 797
 798         * host/lib/usrp_basic.cc (initialize): enabled xrun status polling.
 799         (set_fpga_rx_sample_rate_divisor,set_fpga_rx_sample_rate_divisor):
 800         set FPGA register to N-1.
 801

 812         * firmware/src/usrp1/spi.c (spi_write,spi_read): clock once w/o
 813         enables for the FPGA's benefit.  We're also clocking one extra
 814         cycle at the end with enables again for the FPGA.  I think we
 815         should remove the extra clocking at the end.
 816
 817 2004-04-17  Eric Blossom  <eb@comsec.com>

 885         firmware and host side.  The combo is now working well.  It is
 886         capable of half duplex reading or writing at 31.25 MB/sec and
 887         (pseudo) full duplex reading and writing at 15.625 MS/sec in each
 888         direction.
 889
 890         In addition, the receive side is decoupled from the transmit side

 921         urb having a non-zero transfer count.
 922
 923         * host/lib/test_fusb.cc (test_output): fixed defective test case
 924         that was having me think the tx code wasn't working.

 951         FPGA clear_status line to the previous location of SDO.  This
 952         means that firmware from here out will only work with the latest
 953         FPGA bitstreams that have this pin configurd as an input.
 954
 955         * host/lib/fusb.{h,cc}: fast streaming usb library built on top of libusb.

1022         firmware/basic_fw/src/fpga.c: changed load_fpga to expect a byte
1023         count, not a bit count in the xfer packet.
1024
1025         * firmware/basic_fw/src/fpga.c (do_fpga_config_start): cleanup,
1026         add appropriate delay.
1027
1028         * firmware/basic_fw/src/usrp_common.c (udelay1, udelay): new delay functions

1031
1032         * firmware/basic_fw/include/fx2regs.h: changed sfr and sbit syntax
1033         to match what SDCC expects.  Now the SFR's are really allocated
1034         where they are supposed to be ;-)
