at86rf215 stops receiving when sam0_eth is in use #19911

Closed benpicco closed 9 months ago

benpicco commented 10 months ago

Description

Steps to reproduce the issue

Attach the REB215-XPRO module to the same54-xpro board and flash e.g. gnrc_networking with the at86rf215 module enabled.

Expected results

Sending and receiving works on the 6lo interface

Actual results

Pinging other boards fails. Doing a udp send ff02::1 1234 test works - other boards can receive the message. Messages sent from other boards (after doing a udp server start 1234) are not received.

Versions

git bisect points to 2a255ff3e80111682aac9df0e2a49974e770ba16 as the first bad commit. With this commit reverted, receiving packets works fine again.

Arg this is a board specific issue: both the PHY IRQ pin and the AT86RF215 IRQ line map to EXTI7 - whoever is initialized last wins.
