Hi, About the bug for fa526, no one can help?
Just be curious why it's claimed to be supported and when it can actually work. ------------------ zzzh.2007 2009-11-06 ------------------------------------------------------------- Sender：Øyvind_Harboe Date：2009-11-06 23:44:29 Receiver：zzzh.2007 CC：David Brownell; openocd-development Topic：Re: [Openocd-development] bugs for FA526 core 2009/11/6 zzzh.2007 <[email protected]>: > Hi, David, > > I just tried at version of 0.4.0-dev-snapshot (2009-11-06-12:53), fails > again, bug exists as before. This is totally as expected. The FA526 is an obscure core and nobody has been working on it for a while. > Yes, i think i'd confirmed there is a bug, for FA526 core. > > I used to check the about code, and i think the bug have biggest possibility > lay in here: > arm7_9->enable_single_step = arm9tdmi_enable_single_step;(at fa626.c:346) > that is, i think fa526 may have different jtag strcture compare with common > arm9tdmi, that's why the wrong instrction excuted. Does the FA526 have hardware for single stepping? If not the software single stepping could be a way to go? Try modifying fa526.c to set has_single_step = 0. -- Øyvind Harboe http://www.zylin.com/zy1000.html ARM7 ARM9 ARM11 XScale Cortex JTAG debugger and flash programmer _______________________________________________ Openocd-development mailing list [email protected] https://lists.berlios.de/mailman/listinfo/openocd-development
