I must correct myself. I've rerun the fresh `master` with `CONFIG_SMP_NCPUS=1` and it's very unstable now. With enabled extra debug output it gets stuck randomly here and there, as if the UART I/O procedure itself interferes with other lock operations. ``` >>> bt #0 spin_lock_notrace (lock=0x20003b0d <g_cpu_irqlock> "\001") at nuttx/include/nuttx/spinlock.h:199 #1 enter_critical_section_wo_note () at irq/irq_csection.c:183 #2 0x1000d37e in uart_xmitchars (dev=0x20000fc8 <g_uart0port>) at serial/serial_io.c:62 #3 0x10000dd4 in up_interrupt (irq=49, context=0x0, arg=0x20000fc8 <g_uart0port>) at chip/rp23xx_serial.c:617 #4 0x10002bb6 in irq_dispatch (irq=49, context=0x0) at irq/irq_dispatch.c:144 #5 0x10001cf4 in exception_direct () at armv8-m/arm_doirq.c:62 #6 <signal handler called> #7 0x10002cf0 in enter_critical_section_wo_note () at irq/irq_csection.c:184 #8 0x100226ac in nxsched_process_scheduler () at sched/sched_processtimer.c:132 #9 0x100226e6 in nxsched_process_timer () at sched/sched_processtimer.c:193 #10 0x100116e0 in rp23xx_timerisr (irq=15, regs=0x0, arg=0x0) at chip/rp23xx_timerisr.c:82 #11 0x10002bb6 in irq_dispatch (irq=15, context=0x0) at irq/irq_dispatch.c:144 #12 0x10001cf4 in exception_direct () at armv8-m/arm_doirq.c:62 #13 <signal handler called> #14 up_idle () at chip/rp23xx_idle.c:94 #15 0x100028be in nx_start () at init/nx_start.c:782 #16 0x100001ec in __start () at chip/rp23xx_start.c:192 [2] id 2 name rp2350.dap.core1 from 0x000000ec [1] id 1 name rp2350.dap.core0 from 0x10002cd0 in spin_lock_notrace+8 at nuttx/include/nuttx/spinlock.h:199 ``` Output in the console looks unfinished: ``` [CPU0] nxsig_tcbdispatch: TCB=0x2000adb0 pid=46 signo=39 code=0 value=0 masked=NO [CPU0] nxsig_tcbdispatch: TCB=0x2000adb0 pid=46 signo=41 code=0 value=0 masked=NO [CPU0] nxsig_tcbdispatch: TCB=0x2000adb0 pid=46 signo=42 code=0 value=0 masked=NO [CPU0] nxsig_tcbdispatch: TCB=0x2000adb0 pid=46 ``` -- This is an automated message from the Apache Git Service.
