Florent Kermarrec 6c429c9995 build/lattice: add ECP5 implementation for SDRInput/SDROutput. 2020-04-09 16:24:05 +02:00
Florent Kermarrec 72c8d590fa litex/gen: add io with SDRInput/SDROutput (if not overrided, register is supposed to be infered). 2020-04-09 16:23:27 +02:00
Florent Kermarrec 8f57321f30 tools/litex_sim: remove LiteSPI support for now since breaking Travis-CI of others sub-projects.
LiteSPI is not mature enough to be integrated in LiteX sim directly. (will case trouble is things are refactored).

This could be re-introduced later when more mature. For now simulation with LiteX Sim
could be tested directly in LiteSPI with a custom simulation.

Florent Kermarrec 9afd017a3a tools/litex_term: increase workaround delay for usb_fifo. (validated on Minispartan6 and MimasA7).
Still needs to be fixed properly.

Florent Kermarrec 30d25ffe5b setup.py: simplify, switch to Python3.6+ (using python_requires), remove version.
- Deprecate Python 3.5, switch to Python 3.6+.
- Remove which was not used or updated. We'll see to get this back when working on releases.

Florent Kermarrec 3f1159fa0b litex_setup: reorganize a bit, add separators/comments. 2020-04-07 11:05:36 +02:00
Florent Kermarrec 926f961bf3 .travis.yml: revert full url for litex_setup.py.
We want to have an almost identical .travis.yml between LiteX and the Cores.
Using $TRAVIS_BUILD_DIR works for LiteX but will not work for the cores.

Merge pull request #450 from mithro/litex-setup-fix
litex_setup: Use subprocess so failures are noticed.
2020-04-06 23:04:47 +02:00
Tim 'mithro' Ansell d781bf2088 Run `litex_setup.py` outside the git clone directory.
Otherwise it tries to overwrite the litex directory by cloning LiteX
into it.

Tim 'mithro' Ansell dd59dac571 litex_setup: Use subprocess so failures are noticed.
os.system doesn't report if any of the commands fail. This means that if
something goes wrong it happily reports success making it hard to debug
issues.

Florent Kermarrec 0f352cd648 soc/cores: use reset_less on datapath/configuration CSRStorages. 2020-04-06 13:17:14 +02:00
Florent Kermarrec a67ab41835 interconnect/csr: add reset_less parameter.
In cases CSRStorage can be considered as a datapath/configuration register and does not need to be reseted.

Florent Kermarrec 91981b960c soc/cores/uart: use reset_less on accumulator, reg, bitcount to reduce.
This reduces logic a bit. It does not make large difference on usual design with
only 1 UART, but is interesting on designs with hundreds of UARTs used to "document"
FPGA boards :) (similar to https://github.com/enjoy-digital/camlink_4k/blob/master/ios_stream.py)
