Hi
Wifi on my NEO Z83-4U V2 64G is not working anymore.
I bought NEO Z83-4U with Ubuntu preinstalled and Wifi working. Then I tried to update to Ubuntu 20 and the disaster started,
I tried all hints in the forum so far (re install ubuntu 18 for NEO Z83-4U, install ubuntu 20 for NEO Z83-4U, https://theminixforum.com/index.php...evices-on-different-linux-distributions.3536/, etc,). Nothing works.
Also, after reinstalling ubuntu 18 for NEO Z83-4U or ubuntu 20 for NEO Z83-4U, I did not find the MINIX specific files like "brcmfmac43455-sdio.MINIX-NEO Z83-4.txt" in /lib/firmware/brcm
dmesg says:
[ 6.435864] brcmfmac: brcmf_chip_tcm_rambase: unknown chip: 43454
[ 6.435873] brcmfmac: brcmf_chip_get_raminfo: RAM base not provided with ARM CR4 core
[ 6.435878] brcmfmac: brcmf_sdio_probe_attach: brcmf_chip_attach failed!
[ 6.435884] brcmfmac: brcmf_sdio_probe: brcmf_sdio_probe_attach failed
[ 6.437029] brcmfmac: brcmf_ops_sdio_probe: F2 error, probe failed -19...
[ 6.438135] usbcore: registered new interface driver brcmfmac
Is there a solution for this very chip ( 43454)?
Thanks, Chris
