Well, the Xburst-arch seems to be pretty fucked up beyond all repair. //Markus On 6 Mar 2009, at 17:36, Nils Faerber wrote:
Hello! I am rather playing than really working on a Ingenic JZ4730 based device. The JZ4730 is a MIPS32 SOC included in many types of devices, like media players and thelike but also in small power efficient subnotebooks (this is the device I am trying to support based on the Ingebic Linux kernel patch). The current kernel patch from Ingenic http://www.ingenic.cn/eng/productServ/App/JZ4730/pfCustomPage.aspx or ftp://ftp.ingenic.cn/3sw/01linux/02kernel/linux-2.6.24/linux-2.6.24.3-jz-20090218.patch.gzfor the patch (I used an even older patch to start my board support butthey basically only added newer CPU types in later patches).The support for my board is almost in place but I see from time to timefailing applications with "illegal instruction" faults. Most shellapplications work pretty fine, especially more complex GUI applicationsseem to fail, like a webbrowser or such. I also tested this with different GCC and glibc version which makes me pretty sure that I am seeing a kernel problem here rather than a userspace problem. I am pretty clueless how to debug this. Apropos debig as another hint: Some application work if I start them in GDB but fail outside.Any hint how to start debugging this would be greatly appreciated! And afix would be like a dream ;) Many thanks!
