Booting multiple wl12xx and wl18xx devices using the same rootfs is a pain. You currently have to symlink the right nvs file depending on the wl12xx type. For example, with wl1271-nvs.bin being a symlink to wl127x-nvs.bin by default and trying to bring up a wl128x based device: wlcore: ERROR nvs size is not as expected: 1113 != 912 wlcore: ERROR NVS file is needed during boot wlcore: ERROR NVS file is needed during boot wlcore: ERROR firmware boot failed despite 3 retries Note that wl18xx uses a separate config firmware wl18xx-conf.bin that can be generated with tools using the following two git repos: git.ti.com/wilink8-wlan/18xx-ti-utils git.ti.com/wilink8-wlan/wl18xx_fw So let's not configure the nvs file for wl18xx as it's not needed AFAIK. If it turns out that we also need the nvs file for wl18xx, we can just add it to the config firmware data for wl18xx. Let's fix the issue by using the chip specific config firmware data, and make sure we produce understandable warnings if something is missing.
