Hi @shtirlic, after enabling the FPU on RP2350 it now locks up during a startup in SMP configurations. Here are the only culprits I have at the moment: ``` [rp2350.dap.core1] clearing lockup after double fault [rp2350.dap.core1] external reset detected Thread 1 "rp2350.dap.core0" received signal SIGINT, Interrupt. 0x100121b2 in up_cpu_start (cpu=1) at chip/rp23xx_cpustart.c:252 252 while (!g_core1_boot); warning: ARM M in lockup state, stack unwinding terminated. >>> where #0 0x100121b2 in up_cpu_start (cpu=1) at chip/rp23xx_cpustart.c:252 #1 0x10002ba8 in nx_smp_start () at init/nx_smpstart.c:133 #2 0x10002a6a in nx_start () at init/nx_start.c:749 #3 0x100001f0 in __start () at chip/rp23xx_start.c:196 >>> list 247 /* Enable inter-processor FIFO interrupt */ 248 249 irq_attach(RP23XX_SIO_IRQ_FIFO, rp23xx_smp_call_handler, NULL); 250 up_enable_irq(RP23XX_SIO_IRQ_FIFO); 251 252 while (!g_core1_boot); 253 254 /* CPU Core 1 boot done */ 255 256 return 0; >>> ``` Reducing `CONFIG_SMP_NCPUS` to 1 helps avoid it, and I suppose getting rid of SMP also. This is on current master with the `pimoroni-pico-2-plus:smp` configuration. -- This is an automated message from the Apache Git Service.
