Florent Kermarrec 6a5f2f59a6 targets/orangecrab: use new ECP5DDRPHY's cmd_delay to add extra delay on DDR3's Clock/Commands. 
This fixes https://github.com/enjoy-digital/litedram/issues/130 and has been tested
at 48/64/96MHz on MT41K64M16 and MT41K512M16 variants.

Also remove un-needed cd_sys2x_eb.

Florent Kermarrec d73bd2f7ce targets/xilinx: add comment on sys_clk to pll.clkin false path. 2021-01-07 08:01:54 +01:00
Florent Kermarrec 1ac1c6857f targets/xilinx: add false path constraint between sys_clk and pll.clkin. 
The SoC reset added recently creates a path between sys_clk and pll.clkin
clock domains that is reported by the tools but that can be safely ignored.

Geert Uytterhoeven 4a95b94dbf platforms/ecp5: Fix slewrate configuration 
When building linux-on-litex-vexriscv for OrangeCrab:

    Warning: IOBUF 'spisdcard_clk' attribute 'SLEW' is not recognised (on line 207)
    Warning: IOBUF 'spisdcard_mosi' attribute 'SLEW' is not recognised (on line 210)
    Warning: IOBUF 'spisdcard_cs_n' attribute 'SLEW' is not recognised (on line 214)
    Warning: IOBUF 'spisdcard_miso' attribute 'SLEW' is not recognised (on line 218)

Platforms using litex.build.lattice.LatticePlatform seem to support only
"SLEWRATE", not "SLEW".  Fix the few offenders in the LogicBone and
OrangeCrab platform definitions.

Florent Kermarrec 9beaf25822 nexys4ddr: fix eth/int_n pin (B8) and use 4-bit on vga.blue. 2020-12-24 10:15:29 +01:00
Sahaj Sarup 2a04c5c74e nexys4ddr: add support for litexvideo VGA Terminal 
This commit adds VGA support for the Nexys A7/ Nexys 4 DDR.

The VGA is however limited to RGB443 instead of the full 12bit RGB444.
This is because IO D8 which is MSB for Blue, is also used for ETH int_n.
This makes the final output have a yellow tint.
