Updated broadcom/BCM4345C0.hcd firmware doesn't load. #3

Closed satmandu closed 6 years ago

satmandu commented 6 years ago

Does this new firmware work in existing systems or does it need new userspace code?

On 3b+ running on arm64 I see the following with the earlier firmware from here: https://github.com/RPi-Distro/bluez-firmware/commit/09eeca34619a1691ad2983d355a9301db75f0456

In contrast with this newer firmware from here https://github.com/RPi-Distro/bluez-firmware/commit/ade2bae1aaaebede09abb8fb546f767a0e4c7804 bluetooth just never comes up (loading the firmware leads to an initialization timeout):

We use a patched version of hciattach on Raspbian and I've read that hciattach has been superseded by another tool and also that the newer versions of the kernel can load the firmware directly. I'm afraid I can't give any specifics on the alternative approaches.
