Hi

Not quite sure if I'm following,  but
/lib/firmware/brcm/brcmfmac43455-sdio.bin
exists and is identical to
package/brcmfmac-firmware/src/brcmfmac43455-sdio.bin
from the latest adk revision.
This would mean it's not the problem described in the link?

But the difference is, the driver is loading, it tries to open and
load the binary firmware blob and then fails with error -2.

My system fails when the wifi chip is detected on the SDIO bus early
not even trying to load any wifi driver at all.

[    2.015329] brcmfmac: F1 signature read @0x18000000=0x15264345

So either simply the file does not exist in /lib/firmware/brcm/brcmfmac43455-sdio.bin
or we have the wrong one like discussed here: https://patchwork.codeaurora.org/patch/248789/

See include/uapi/asm-generic/errno-base.h
#define ENOENT          2      /* No such file or directory */

You have latest files in package/brcmfmac-firmware/src
file brcmfmac43455-sdio.bin
brcmfmac43455-sdio.bin: data
