Florent Kermarrec 296688b2d8 cores/jtag/ECP5JTAG: Fix LUT4's INIT to create a buffer instead of inverter, thanks @gregdavill.
Avoid restriction to even number for tck_delay_luts.

Florent Kermarrec 0b40d78b0d cores/jtag/ECP5JTAG: Delay TCK with LUT4 to avoid sys_clk/jtag_clk relationship and support higher jtag_clk frequencies.
Tested succesfully on the ButterStick with 75MHz sys_clk/25MHz jtag_clk.

Current tck_delay_luts is abritrary and should probably be adjusted.

Florent Kermarrec 9b4c7e8288 README/litex_setup: Remove reference to LiteVideo to encourage use of LiteX's VideoTerminal/Out core.
LiteVideo is not longer maintained, does not have CI and is messy (code is ~10 years old where we were
still experimenting the innovative approach with Migen). The core is kept since can be useful as reference
for Video Input and for projects using it but it is not recommended for new designs.

Florent Kermarrec 47b3c9bc08 soc/interconnect/packet: Remove last_be support in LiteX, specialized Packetizer/Depacketizer have been moved to LiteEth to simplify development and avoid eventual regresion on others cores.
As seen during the last LiteEth developments, last_be data qualifier is not easy to handle correctly and should be replaced by a simpler data qualifier (similar to AXI's tkeep/tstrb). It will
be easier to do so by having a local copy of Packetizer/Depacketizer directly in LiteEth (still with last_be support) and work on the simpler data qualifier in LiteX (and test it on LitePCIe).

litex_sim/xgmii_ethernet: fix RX frame check sequence generation
2021-10-25 10:30:05 +02:00
Leon Schuermann f2a622975a litex_sim/xgmii_ethernet: fix RX frame check sequence generation
The rewritten XGMII Ethernet module generates proper frame check
sequences (FCS) on Ethernet frames received by the simulation, such
that the unmodified MAC pipeline including CRC checking can be
used. However, the byte order of the generated frame check sequence
has been inverted. This becomes apparent when one specifies that the
CRC should be calculated in the LiteX BIOS.

This fixes the byte order to be correct. The similar GMII Ethernet
module did not contain this mistake.
