Subject: can: flexcan: problems with bus error reporting om i.MX53
Date: Fri, 25 Jul 2014 20:16:34 +0200 [thread overview]
Message-ID: <53D29F02.8010708@optimeas.de> (raw)
Hi all,
we had the following problems when we enabled bus error reporting on an
i.MX537 (Ka-Ro TX53-8130):
- interrupt flooding when sending a packet on an open bus
- bus state change notifications did not work properly
- second bus state change after bus recovery was not properly notified
The patches in the next mails fix all these problems and are tested
against mainline linux 3.12.24-rt38 with PREEMPT_RT patch.
Best regards,
Matthias Klein
