Florent Kermarrec 5257197475 bench: add DDR4 Mode Register settings generator. 
Useful to change timing/electrical settings dynamically and bringup/debug DDR4 on new hardware.
 2020-09-24 14:57:14 +02:00
Florent Kermarrec 06544c6547 bench: uniformize targets with 125MHz clock and Etherbone. 2020-09-24 13:03:07 +02:00
Florent Kermarrec 6fc6174c38 bench/genesys2: expose uart parameter. 2020-09-17 08:22:17 +02:00
Florent Kermarrec 6a5f2fdb09 bench/genesys2: add uart_name parameter. 
Useful when Etherbone is just used to reload BIOS.
 2020-09-14 18:43:33 +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 6a75aa0ad7 bench/common: add s7_load_bios/s7_set_sys_clk functions. 2020-09-14 10:54:35 +02:00
Florent Kermarrec 7eeea34c4e bench: use 115200bauds UART on all targets (fast enough and simplify switch betwen targets). 2020-09-14 10:05:55 +02:00
Florent Kermarrec 543a94dd33 bench/common: enable load_rom on kcu105 (with delay workaround). 2020-09-03 17:46:50 +02:00
Florent Kermarrec 7d0dac78c5 bench/kcu105: add a second pll to reduce frequency steps. 2020-08-28 19:03:44 +02:00
Florent Kermarrec 1fb78fa558 bench: cleanup, do more testing on 7-series. 2020-08-28 17:57:59 +02:00
Florent Kermarrec 248c5de517 bench: switch to UARTBone to simplify (and to allow testing boards without ethernet capability) and improve test. 2020-08-28 03:47:49 +02:00
Florent Kermarrec 6f2462b731 bench: add kc705. 2020-08-27 19:05:17 +02:00
Florent Kermarrec d3502e6a9b bench: add common.py with common bench test code. 2020-08-27 19:05:05 +02:00
Florent Kermarrec 2e3e19e9d4 bench: simplify/improve, working on arty/genesys2. 2020-08-27 18:41:54 +02:00
Florent Kermarrec 5c69da5d6d bench: add initial kcu105 bench target. 2020-08-24 21:56:11 +02:00
Florent Kermarrec 9995c0fefb bench: switch integrated_rom to "rw" mode and reload it over Etherbone at startup. 
This simplifies software development.
 2020-08-24 18:40:54 +02:00
Florent Kermarrec ac825e5112 add SPDX License identifier to header and specify file is part of LiteDRAM. 2020-08-23 15:52:08 +02:00
Florent Kermarrec 94241d0583 bench: use new platform.request_all on LedChaser. 2020-08-06 20:03:03 +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
