## Summary - This commit fixes a deadlock problem in up_txint() for cxd56xx. - Because uart_xmitchars() called by up_txint() takes a lock by enter_critical_section(), taking a spinlock here can cause a deadlock. ## Impact - This commit affects the cxd56_serial driver in SMP mode only. ## Testing - Tested with spresense:smp ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
