SourceForge bug #33 from Fabien Comte (2014-9-17). - + * arch/arm/src/stm32/stm32_can.c: At the end of the interrupt handler, + the interrupts were being disabled, if all packets have been + transferred when the interrupt handler was invoked. This is + problematic, because the interrupt handler calls can_txdone of the + upper half which can enqueue new packets to send. Removed the block + altogether, because can_txdone calls can_xmit which disables + interrupts if there are no new packets to send. From Daniel Lazlo + Sitzer (2103-9-17). + * drivers/can.c: In can_txdone, waiters on the semaphore should be + informed regardless of the return value of can_xmit. First it returns + -EIO if there are no new packets, and second the information of the + waiters is about the last transferred packet. From Daniel Lazlo + Sitzer (2103-9-17). |
