The FW files are hosted on the Infineon GitHub, except for the 2AE-USB and 2BC-USB FW files. These need to be built manually, because the USB FW contain Murata specific NVRAM files integrated.

Place the downloaded production FW file in "/lib/firmware/cypress" folder before loading the driver. Refer to the table below for the firmware files.

1LV (CYW43012): Longma | Kraken | Jaculus | Indrik | Hedorah | Godzilla | Fafnir | Ebirah | Drogon | Cynder | Baragon

2GF (CYW43022): Longma | Kraken | Jaculus | Indrik

1DX/1FX (CYW43430): Longma | Kraken | Jaculus | Indrik | Hedorah | Godzilla | Fafnir | Ebirah | Drogon | Cynder | Baragon

1YN (CYW43439): Longma | Kraken | Jaculus | Indrik | Hedorah | Godzilla | Fafnir | Ebirah | Drogon | Cynder | Baragon

1MW (CYW43455): Longma | Kraken | Jaculus | Indrik | Hedorah | Godzilla | Fafnir | Ebirah | Drogon | Cynder | Baragon

2AE-SDIO (CYW4373E): Longma | Kraken | Jaculus | Indrik | Hedorah | Godzilla | Fafnir | Ebirah | Drogon | Cynder | Baragon

2BC-SDIO (CYW4373): Longma | Kraken | Jaculus | Indrik | Hedorah | Godzilla | Fafnir | Ebirah | Drogon | Cynder

2AE-USB (CYW4373E): See Note

2BC-USB (CYW4373): See Note

1XA/2BA (CYW54591): Longma | Kraken | Jaculus | Indrik | Hedorah | Godzilla | Fafnir | Ebirah | Drogon | Cynder | Baragon

2BZ (CYW54590): Longma | Kraken | Jaculus | Indrik | Hedorah | Godzilla | Fafnir | Ebirah | Drogon | Cynder | Baragon

2FY (CYW55513): Longma | Kraken | Jaculus

2EA-PCIe (CYW55573): Longma | Kraken | Jaculus | Indrik | Hedorah | Godzilla | Fafnir | Ebirah

2EA-SDIO (CYW55573): Longma | Kraken | Jaculus | Indrik | Hedorah | Godzilla | Fafnir | Ebirah

1. For 2AE-SDIO, rename the "cyfmac4373-sdio.industrial.bin" FW file to "cyfmac4373-sdio.bin" before using.
2. For 2AE-USB, refer to the Murata IFX Linux User Guide on how to build the firmware.
3. For 2BC-USB, refer to the Murata IFX Linux User Guide on how to build the firmware.
4. Same firmware file (cyfmac54591-sdio.bin) is used for 2BZ and 1XA. 2BZ is based out of IFX chipset 54590.
