Hat not connecting to raspberrypi 4 after brickd upgrate to 2.4.6

[dwisk]

Hi,

after updating brickd to 2.4.6 it does not connect to the hat anymore on a Raspberry Pi 4 Model B Rev 1.5. (Hat firmware did not show any available updates before). I checked that SPI is enabled.

Any ideas on what went wrong? Also downgrading to brickd 2.4.3 seems not available with aptget. There it did connect.

This is a known problem that will be fixed with 2.4.7.

Were you able to downgrade to 2.4.3? If not, you can download older versions from here.

See the thread Brick Daemon 2.4.6 not working for

• a discussion of the problem
• instructions for downgrading to brickd 2.4.5 (fix)
• a preview of brickd 2.4.7 (alternate fix)

[MatzeTF]

Please note that the brickd 2.4.7 preview in that thread is for armhf, not arm64, which is what the OP is running.

brickd 2.4.7 is now available from our APT server.
