*.fs* file is the default format generated by *Gowin IDE*, so nothing
|
|
|
|
|
special must be done to generates this file.
|
|
|
|
|
|
|
|
|
|
Since the same file is used for SRAM and Flash a CLI argument is used to
|
|
|
|
|
specify the destination.

### Flash SRAM
|
|
|
|
|
|
|
|
|
|
with **-m**
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
openFPGALoader -m -b BOARD_NAME impl/pnr/*.fs
|
|
|
|
|
```
|
|
|
|
|
where *BOARD_NAME* is:
|
|
|
|
|
- *tec0117*
|
|
|
|
|
- *tangnano*
|
2021-09-02 13:54:34 +02:00
|
|
|
- *tangnano4k"
|

|
|
|
- *runber*
|
|
|
|
|
|
|
|
|
|
### Flash (only with Trenz TEC0117 and runber):
|
|
|
|
|
|
|
|
|
|
with **-f**
|
|
|
|
|
|
|
|
|
|
__file load__:
|
|
|
|
|
```bash
|
|
|
|
|
openFPGALoader -f -b BOARD_NAME impl/pnr/*.fs
|
|
|
|
|
```
|
|
|
|
|
where *BOARD_NAME* is:
|
|
|
|
|
- **tec0117**
|
|
|
|
|
- **runber**

It's possible to flash external SPI Flash (connected to MSPI) in bscan mode
|
|
|
|
|
by using `--external-flash` instead of `-f`
|
