* [ECOS] Timer tick dosen't work, when printf string > 24 [not found] <dd9328150604110059j6587149ek81a127cff19e286@mail.gmail.com> @ 2006-04-11 8:10 ` 廖友鍾 2006-04-11 8:20 ` Andrew Lunn 0 siblings, 1 reply; 3+ messages in thread From: 廖友鍾 @ 2006-04-11 8:10 UTC (permalink / raw) To: ecos-discuss Hi, I used Sumsung s3c2410 development board(SMDK2410) to run simple-alarm example program. I add LED flash function in hal_clock_reset() and add one line printf function in cyg_user_start() in simple-alarm.c file. void cyg_user_start(void) { printf("12345678901234567890123\n");//Add one line prinf function here cyg_thread_create(4, alarm_prog, (cyg_addrword_t) 0, "alarm_thread", (void *) stack[0], STACKSIZE, &thread[0], &thread_obj[0]); cyg_thread_resume(thread[0]); } If string lenth in prinf function is small than 24, the timer tick is working correctly and LED flashing. If I modify printf("123456789012345678901234\n"), now the string lenth become 25 then time tick dosen't work and LED dosen's flashing. This is very strange problem. -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss ^ permalink raw reply [flat|nested] 3+ messages in thread

No, not really.
