Gwenhael Goavec-Merou ecaebfe645 phy/trionrgmii.py: fixed RX and TX sides. RX: forces phase align by usign it as PLL's feedback. TX: reduces PLL phase shift 90 -> 45 2024-09-03 15:08:09 +02:00

mac/__init__.py: Fix LiteEthMAC. 
This fixes LiteEthMAC and
LiteEthMACCoreCrossbar.

Its also renames the depacketizer in
LiteEthMACCoreCrossbar for mac filtering
to filter_depacketizer, so it is not mixed up
with self.depacketizer.

Matthias Breithaupt 7b4429e814 Fix etherbone reads 
Since https://github.com/enjoy-digital/litex/pull/1999, etherbone reads
might result in garbage being output. This is caused by `be` not being
set during the read.

Fixes https://github.com/enjoy-digital/litex/issues/2031

Matthias Breithaupt 85c3ab2c51 Only import liteiclink when required 
As liteiclink is only used in the phy implementations of a few Xilinx/AMD
FPGAs, it does not make sense that it would be required to build liteeth
for any FPGA.

Update a7_gtp.py 
After testing several boards with XC7A200T chips, I found, that SFP works well only with setting more than 10us. The most of the XC7A200T chips works with 500ns, but some boards need 10us.

Florent Kermarrec ec7320f003 mac/wishbone: Fix ntxslots/nrxslots == 1 case. 
Previously, a common decoder was used for TX and RX slots, so there were at least
two interfaces connected. With the TX/RX decoupling, we now only have on interface
per decoder when ntxslots/nrxslots == 1.
