Florent Kermarrec 4acab79987 sdram/module: cleanup indent 2015-08-20 22:15:06 +02:00
Florent Kermarrec 63538a7d04 litecores: add -Ob option to make.py (allow to build with yosys for example) 2015-08-19 01:17:37 +02:00
Florent Kermarrec c03ef526eb sdram/phy/s6ddrphy: add DDR3 support 2015-08-04 12:29:42 +02:00
Florent Kermarrec 52fba05e26 sdram/phy/initsequence: add burst chop 4 (BC4) for DDR3
This is needed for half rate controllers with burst length of 4.
For best efficiency quarter rate controllers should be used.

Florent Kermarrec 3b9f287bab sdram: use wishbone cache as L2 cache and add optional L2 cache to Minicon 2015-06-17 15:30:30 +02:00
Florent Kermarrec a1f7ecc8c5 litesata: use 200MHz clock and SATA3 (6.0Gb/s) on all example designs: working :) 2015-06-10 12:15:59 +02:00
Florent Kermarrec 571ce5791a litesata/phy/k7: apply AR# 63869 to keep CDR in hold during SATA link initialization
self.rxelecidle is already filtered so the "20 USRCLK cycles before setting RXCDRHOLD to 1'b0" are respected.

Florent Kermarrec 7bdcbc94cd litesata: use (some) settings from vivado 2015.1, try to follow all ug476 recommendations to initialize GTX (...), remove automatic reset on top.
Works fine @ 3Gbps, still not working @6.0Gbps

Florent Kermarrec 1281a463d6 litescope/bridge: create a generic wishbone bridge that can be used with different phys (the phy needs to provide a sink/source with 8bits data).
- we can now pass a phy to LiteScopeWishboneBridge
- LiteScopeUART2Wishbone is only a specific LiteScopeWishboneBridge
- UART mux is removed since complicated and no longer useful (we can now create easily virtual UART over Ethernet, USB or PCIe) or simply add another UART for debug.
