Florent Kermarrec db54e325c8 phy/usddrphy: reduce BitSlip cycles to 1 sys_clk.
Increasing it to 2 hasn't been useful.

Florent Kermarrec 8d39ac6dd1 phy/s7ddrphy: remove interface_type parameter and ISERDESE2's MEMORY_MODE support.
Supporting MEMORY_MODE add complexity to the codebase and this mode is not used by anyone.
It has been experimented on NeTV2 to solves instability at low temperature but hasn't improved
the behaviour.

Florent Kermarrec c3b4b0d338 phy/s7ddrphy: reduce BitSlip's cycles to 1 (seems to be enough for all cases). 2020-09-15 19:50:45 +02:00

2020-09-14 18:43:33 +02:00
Florent Kermarrec f5184b41b5 core/multiplexer/steerel_sel: add support for dynamic rd/rdcmd/wr/wrcmd phases.

2020-09-14 18:40:58 +02:00
Florent Kermarrec 020cff1970 bench/genesys2: add back Etherbone (faster for BIOS dev) and add --load-bios/set-sys_clk arguments. 2020-09-14 10:55:16 +02:00

Florent Kermarrec 74205979bd bench: add genesys2 bench. 2020-08-06 19:19:45 +02:00
Florent Kermarrec 37fb44f33e add bench directory with a first bench on arty board.
The aim is to create an automated hardware bench, control is done over Etherbone
(but could also be done over UARTBone, PCIe, USB, etc...) and various frequencies
are tested and BIOS logged.

It would also be useful to be able to recompile/reload BIOS in this bench to easily
test software changes and verify it works with various frequencies.

Can be tested with:
./arty.py --build --load
lxserver --udp
./arty.py --test
