[rtl] 3.0 pre6d questions (psc and debugger)

I've been trying out the rtl_sigaction feature of RTL3.0 pre6d. It works nicely except for an occasional exception 14 occurring in the psc.o module. I'd like to debug this but when I follow the instructions and use remote target /dev/rtf10, gdb does nothing (ie no prompt, as reported by Stuart

[rtl] Multi-taks multi-threads?

[rtl] FP in rtl threads

I observed that I cannot use floating point arithmetik with the pthread_suspend_np()/pthread_wakeup_np() mechanism (FPU cannot be used by Linux, e.g. "top" hangs). But it seems to be safe using pthread_make_periodic_np()/pthread_wait_np(). Is that correct? [rtl2.2 prepatched kernel]

[rtl] RTL V3 - how to

Hi all, I downloaded prepatched RTLinux V3 beta the other day and installed it on top of Red Hat Linux 6.2. It seems that everything is under the "/usr/src/rtlinux_kernel" directory. The problem is, where are those RTLinux modules? I can't find them anywhere. BTW, is there any detailed doc about

Re: [rtl] RTL V3 - how to

The pre-patched kernel is just that (patched). You'll need to download the rtlinux_3_0_pre6d.tgz (6e is also available) for the rtl modules et al. Here's a few things I noticed: o I had to do a 'make install' as well as running the 'sh ./scripts/insrtl'. o The psc makefile

[rtl] rt_global_sti

Hello RTers A while back a few of you helped with an ISR that looked like this: void pport1_irq(void){ rt_global_sti(); if(lp_count == ctrl[event_num].dat1){ start_time = rt_get_time(); rt_task_resume(); } lp_count ++; } The ISR resumes a previously suspended task after a

Re: [rtl] debugging a module

hi, I get some problem like that. I want to trace into some other modules use "s", but I failed. I write some module A, and module B . The task created by module B called some function in module A. I compile both modules with -g flag. Does the debug module support multi-module

[rtl] IDE flash disk boot problems

Hello all... I've got a PC104 with 16MB chipdisk ide-compatible flash disk that I'm trying to make boot. The original plan was to hold compressed ramdisk on the flash, and run the rt system and module with ramdisk as the rootfs. The rest of the flash would be for logging data alone.
