What firmware are you using? Judging by the fact acquisition by Synaptics happened sometime late 2020/early 2021 I guess it must be Cypress? I'm not really familiar with BCM43456 chip history. Firmware files used are brcm/brcmfmac43456-sdio.{bin,clm_blob,txt} exactly those found at: https://github.com/RPi-Distro/firmware-nonfree/tree/trixie/debian/config/brcm80211/brcm > > > - mainline uboot 2025.10 is used > > > > > > #regzbot introduced: 6d54d93506 _______________________________________________ Linux-rockchip mailing list Linux-rockchip@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-rockchip
