12 * Support 64-bit wide AHB bus in SPWAMBA.
Many thanks to Tam Do for reporting this issue.
* Update SPWAMBA to GRLIB-1.2.2.
jorisvr 2413d 16h /spacewire_light/trunk/rtl/vhdl/
11 spwrecvfront_generic.vhd: Correctly handle situation where incoming Data/Strobe signals are not '0' at the beginning of the link setup.
Many thanks to Goekce Aydos for reporting this bug.
jorisvr 2502d 15h /spacewire_light/trunk/rtl/vhdl/
10 * Fix incorrect "hsize" indication on AHB access. jorisvr 3045d 16h /spacewire_light/trunk/rtl/vhdl/
7 * spwamba: Add tick_out signal.
* spwrecvfront_fast: Simplified data transfer between clock domains.
* Clean up synchronization of data paths between clock domains.
* Upgrade to GRLIB 1.1.0.
jorisvr 3226d 17h /spacewire_light/trunk/rtl/vhdl/
6 * Add RTEMS driver and test program for SPWAMBA.
* Add documentation for SPWAMBA.
* spwamba: Change TX FIFO management; start new transfer when there is room
for a maximum burst instead of aiming for 3/4 fill rate.
* spwamba: Do not reset spwxmit in response to software reset.
* spwamba: Fix bug in maximum burst size calculation.
* spwamba: Optimize address generation in burst state machine.
* spwamba: More careful calculation of RX credit.
jorisvr 3296d 23h /spacewire_light/trunk/rtl/vhdl/
5 * Add AMBA interface (preliminary version, untested, undocumented).
* License changed from LGPL to GPL.
* Again fix an issue with EEP injection on link loss.
* Add DATAPATHONLY keyword to timing constraints.
jorisvr 3369d 17h /spacewire_light/trunk/rtl/vhdl/
4 * Fixed issue with automatic discarding of TX data after link error.

* After link error, spwstream will terminate current packet with EEP even if the linkdisable signal is active.

* Added code comment to clarify a dependency between spwrecv and spwlink.
(Thanks to Rafael Corsi Ferrao for reporting this obscurity.)
jorisvr 3379d 00h /spacewire_light/trunk/rtl/vhdl/
3 * Added manual.

* Fix incorrect bitrate during link handshake. The system clock frequency was used to compute the initial tx clock divider, even when the clock divider would act on the txclk instead of the system clock.

* Improve fast transmitter. Sending FCT tokens at high bit rate no longer causes insertion of a NULL token.
jorisvr 3440d 16h /spacewire_light/trunk/rtl/vhdl/
2 Initial check-in. jorisvr 3474d 21h /spacewire_light/trunk/rtl/vhdl/
