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	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	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	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.
