targets: Switch to LiteX byte size definitions.
2024-06-13 10:04:19 +02:00

sipeed_tang_nano_4k: Switch to LiteX's UART and expose hyperram parameter.
2024-01-11 13:54:44 +01:00

sipeed_tang_nano_4k: Remove note since openFPGALoader regression has been fixed.

targets/sipeed_tang_nano_4k: Directly integrate flashing of EMCU flash.
...
Ex to build/flash bitstream + firmware with EMCU:
./sipeed_tang_nano_4k.py --cpu-type=gowin_emcu --build --flash

targets/sipeed_tang_nano_4k: adding description to write Gowin EMCU firmware
2023-12-14 13:24:57 +01:00
f400179b5b
targets: Import all from litex.gen on all targets.
2023-02-23 09:09:33 +01:00

targets/BaseSoC: Cleanup parameters.
2022-11-08 12:31:49 +01:00
9e7079c4c8
targets: Remove int() on BaseSoC's sys_clk_freq.
2022-11-08 11:54:17 +01:00
b0e6414519
targets: Cleanup arguments and switch --sys-clk-freq to float (avoid conversion in code).
2022-11-08 10:41:35 +01:00
16b9677acd
targets: Switch to soc_core_argdict.
...
The next move was to remove soc_core and only keep soc; so this is probably the right time to do
it in targets to avoid having to handle it later.
2022-11-07 08:43:26 +01:00
33b0400aed
targets: Update LiteXArgumentParser imports.
2022-11-06 21:39:52 +01:00
9960f38d95
targets: replace LiteXSoCArgumentParser by LiteXArgumentParser, remove tasks done LiteXArgumentParser
2022-11-06 11:27:47 +01:00

targets/sipeed_tang_nano_4k: replacing VideoHDMIPHY by VideoGowinHDMIPHY and adding with-video-terminal arg
2022-09-06 19:08:01 +02:00
45494f60e0
targets: Change SoC/Software headers generation behaviour (Now only generated with --build).
...
Re-generating the SoC/Software headers was causing some un-expected behaviours for users not familiar
with the flow. For example doing a --load with a different configuration, was re-generating the Software
headers and messing up things when trying to run software on the SoC.
2022-05-06 15:14:32 +02:00
28da4f83eb
targets: Use new HyperRAM's sys_clk_freq parameter.
2022-05-02 16:43:52 +02:00
877bc4b45e
targets: Use full imports (vendor_board).
2022-05-02 12:55:11 +02:00
a611f035d6
targets: Move CRG before SoCCore init (More logical and simplify some specific reset schemes) and switch SoCCore to one line when possible.
...
Moving CRG simplify reset with NaxRiscv debug module and is in fact more logical.
Also do some minor updates/cosmetic changes while touching CRG/SoCCore.
2022-04-21 12:19:45 +02:00
9d452b0d74
targets: Create target_group for target arguments.
2022-03-21 18:37:40 +01:00
cc8da9d341
targets: Simplify imports and switch to LiteXSocArgumentParser.
...
CPU parameters are now selectively exposed to the user:
./digilent_arty.py --cpu-type=vexriscv_smp --help will show VexRiscv-SMP parameters.
./digilent_arty.py --cpu-type=naxriscv --help will show NaxRiscv parameters.
2022-03-21 16:59:40 +01:00

targets/gowin: Switch to get_bitstream_filename.
2022-03-17 09:40:10 +01:00

tang_nano_4k: Review/Cleanup:
...
- Revert abstractions on clk_name/period: Too much abstraction to avoid duplications makes the code more difficult to read.
ex:
- When constraining clk27, frequency is already in the name.
- In the target, we want to know we are using clk27 as the main clk.
- We need a default sys_clk_freq for project only importing BaseSoC.
- Revert SPI Flash import (for consistency with other targets).
- Keep VexRiscv as default CPU since this target is able to run it and also for consistency with other targets.

targets: Update and simplify SPI-Flash support (Address is now automatically allocated).
2022-01-07 10:34:47 +01:00

targets/parser: Rely on argparse.ArgumentDefaultsHelpFormatter to provide default in help description.
...
Also do minor adjustments while doing this.
