Florent Kermarrec 6fc87f7c85 build/gowin/common: Add DDRInput/DDROutput implementations. 2021-07-14 10:01:54 +02:00
Florent Kermarrec a8cea15b95 cores/clock/gowin_gw1n/create_clkout: Add reset support (through AsyncResetSynchronizer) and enable it by default. 
Should be based on PLL's lock but does not seem stable, so use reset input for now.

Florent Kermarrec bc77aa37f0 include/hw/common: Fix _csr_rd_buf/_csr_wr_buf for sizeof(buf[0]) < CSR_DW_BYTES case. 
- Shift in _csr_rd_buf should only been done when buf is set.
- When CSR size is not an exact multiple of the CSR data-width, the gap is in
the low addresses, not the high ones. So offset is introduced to take this into
account.

Florent Kermarrec b29a99cd0b liblitedram/sdram.c: Fix DFII_PIX_DATA_BYTES computation. 
DFII CSR size is not necessarily multiple of 4 (often the case but not with ECC for example).

Merge pull request #964 from niw/increase_macos_ttyusbmodem_delay 
Increase delay for `tty.usbmodem` on macOS.
 2021-07-06 18:51:28 +02:00
Yoshimasa Niwa 0953c52eea Increase delay for `tty.usbmodem` on macOS. 
**Problems**

On macOS USB CDC ACM, which appears as `/dev/tty.usbmodem*`,
somehow `lxterm` keeps failing to send a payload.

**Solution**

Increase delay.

It's very unknown why to me, however, probably macOS USB CDC ACM
driver implementation issue.

**Testing**

Tested on MacBook Air (2020, M1) for OrangeCrab (rev.0.2) target
with Linux on LiteX SoC bitstream build from current commit and
load prebuild Linux On LiteX image.

Sylvain Munaut 38e46bb3d3 build/DFUProg: Allow to specify alt interface and to not reboot 
Some targets have multiple alt settings for DFU for different zone
of the flash. Allowing to specify which one to flash and not
rebooting immediately allows to flash several of them at once.
