> **Important:** Select your firmware downloads carefully. If you are using a Seeed Studio HaLow board, you typically want an image with `spi` in the name.
### HaLow Interface Guidance (SPI vs SDIO)
- `spi` images are intended for SPI-based HaLow HATs (most commonly the Seeed WM1302 + Wio-WM6108 setups).
- `sdio` images are intended for SDIO-based HaLow modules (for example Silex or Alfa SDIO boards).
> Note: SDIO images can work across different SDIO boards, but the board configuration file (BCF) must match your specific radio/module. The default BCF is tuned for an Alfa board; for other SDIO boards you will need to obtain the correct BCF from the manufacturer and apply it.
### SBC Target Mapping
Use this as a quick guide for the `rpiX` part of the filename:
| SBC | Use firmware with |
|-----|-------------------|
| Raspberry Pi 4 / CM4 | `rpi4` |
| Raspberry Pi 3B | `rpi3` |
| Raspberry Pi Zero 2 W (Pi2W) | `rpi3` |

## Image Type: `sysupgrade`

Notes:
- Select firmware downloads carefully: the board type, Morse Micro chipset (MM6108 vs MM8108), and interface (SPI vs SDIO) are part of the firmware filename.
- On SDIO-based HaLow builds, onboard Wi‑Fi usually cannot be used due to SDIO bus conflicts.
- On SPI-based HaLow builds, onboard Wi‑Fi can be used for client access (AP mode).
- In general, `spi` images are for SPI-based Seeed HaLow boards; `sdio` images are for SDIO-based modules (for example Silex or Alfa).

@ -68,6 +69,7 @@ Notes:
Some HaLow radios use board configuration files (BCF) to set calibration and regulatory parameters.
- SDIO images ship with a default BCF tuned for an Alfa SDIO board. If you are using a different SDIO module (for example Silex), you will need to obtain the correct BCF from the manufacturer and apply it.
- A BCF for the Alfa AHM26108D is included, but it is **not loaded by default** and must be applied manually for now.
