Hello again, >>Maybe >>this is related to an interrupt with a too high priority, see also: >>https://lists.rtems.org/pipermail/users/2019-April/033102.html
I have played around with priorities but no luck. >>What type of fatal error are you seeing? *** FATAL *** fatal source: 9 (RTEMS_FATAL_SOURCE_EXCEPTION) R0 = 0x20009040 R8 = 0x00000001 R1 = 0x2000374c R9 = 0x00000005 R2 = 0x20009040 R10 = 0x2000f0d8 R3 = 0x00000000 R11 = 0x00000005 R4 = 0x20009040 R12 = 0x00000000 R5 = 0x00004000 SP = 0x2000a1b8 R6 = 0x2000ecf8 LR = 0x0000980b R7 = 0x00000002 PC = 0x20003c80 XPSR = 0x60000000 VEC = 0x00000003 RTEMS version: 5.0.0.46b8638288a51cc175067be12a20301b3fb83ec7-modified RTEMS tools: 7.3.0 20180125 (RTEMS 5, RSB f07d2b6e9ad70d62eb617a9f5515c5045ee0c119, Newlib 08eab6396f678cf5e5968acaed0bae9fd129983b) executing thread ID: 0x08b010002 executing thread name: My application is a wlan ap initialization using TI sdk for cc3100. Using this sdk, I'm creating separate tasks. Actually sequence of my actions are: 1. pthread_create(&wlan_ap_thread_id, NULL, run_wlan_ap, NULL); 2. Wait interrupt signal from chip 3. Spawn a new thread using message queue. 4. Start some kind of SDK magic: transmission via SPI. As I can see from output before fatal there are over 8 successful transmission, the last what I see it's a starting reading 8 bytes from device after that fatal occured. >>I think you can trace the PC pointer to see what makes the FATAL. using gdb: info symbol 0x20003c80 I'm getting _POSIX_Threads_Objects + 2512 in section .bss What am I missing?
