I use mmap() to map a memory and mem_offset() to get the physical address. I find that when I use mem_offset() to get the physical address, this function always return Error EOVERFLOW; but when I use mem_offset64(), mostly the physicalAddressA can return the correct value(the value is larger than 2G), and sometimes it returns value 0 or 1 also. could you tell me why? this can appear on QNX6.5.0 SP1 system, and the platform is Intel Core i7-3610QE pocessor on x86 with 4G DDR3 RAM. but if I change the DDR3 RAM to 2G, it is disappear. the mem_offset() can work OK! the source code is as follow: void *virtualAddressA; off_t physicalAddressA; int mem_offset_flag = 0; int size = 7800; virtualAddressA = mmap( 0, size, PROT_READ|PROT_WRITE|PROT_NOCACHE, MAP_PHYS|MAP_ANON, NOFD, 0 ); if (virtualAddressA == MAP_FAILED) { perror("mmap"); exit(EXIT_FAILURE); }else{ printf("mmap succeed\n"); } // mem_offset_flag = mem_offset( virtualAddressA, NOFD, size, &physicalAddressA, 0); mem_offset_flag = mem_offset64( virtualAddressA, NOFD, size, &physicalAddressA, 0); if(mem_offset_flag == -1) { printf("mem_offset error: %s!\n",strerror(errno )); } Tue, 11 Nov 2014 05:42:03 GMT http://community.qnx.com/sf/go/post112309 yu angel 2014-11-11T05:42:03Z post111222: RE: 请教关于command line问题 http://community.qnx.com/sf/go/post111222 下面这个连接对你有帮助吗? http://www.qnx.com/developers/docs/660/topic/com.qnx.doc.neutrino.user_guide/topic/cmdline.html?resultof=%22%63%6f%6d%6d%61%6e%64%22%20%22%6c%69%6e%65%22%20 Best Regards, Harry Yu _______________________________________________ General http://community.qnx.com/sf/go/post111217 To cancel your subscription to this discussion, please e-mail general-china_technology-unsubscribe@community.qnx.com Fri, 25 Jul 2014 13:43:13 GMT http://community.qnx.com/sf/go/post111222 Harry Yu 2014-07-25T13:43:13Z post111217: 请教关于command line问题 http://community.qnx.com/sf/go/post111217 我已经阅读了QNX6.6的部分帮助文档,也有了自己的板卡,但是在编译BSP的时候,总是会看到有通过command line编译,我想请问大家,这个command line是什么工具?是官方给的吗?有没有具体的语言规范?如何使用?我现在用IDE5.0,但是30天试用已经过期。 Fri, 25 Jul 2014 06:06:48 GMT http://community.qnx.com/sf/go/post111217 Li Ming(deleted) 2014-07-25T06:06:48Z post110613: Re: RE: 请问在QNX6.6.0中如何配置audio:default? http://community.qnx.com/sf/go/post110613 Is there another way to have the QMedia class run without CAR 2.1 platform?

"System Architecture" 这本书分析了很多系统概念。 作为开发者, 还应该学习 ”Programmer's Guide". 这本书重点在程序线程, 内存管理,编译和调试。 然后学习 ”QNX Momentics IDE User's Guide". 要用IDE必读这本书。 以上书都可以在网上直接读. http://www.qnx.com/developers/docs/6.5.0/index.jsp Fri, 13 Jul 2012 17:01:15 GMT http://community.qnx.com/sf/go/post94250 Andy Jin(deleted) 2012-07-13T17:01:15Z post94241: Re: 如何学习QNX?第一步! http://community.qnx.com/sf/go/post94241 对新手很有帮助 Fri, 13 Jul 2012 00:33:32 GMT http://community.qnx.com/sf/go/post94241 Wang Renai 2012-07-13T00:33:32Z post94125: Re: 如何获取源码 http://community.qnx.com/sf/go/post94125 我们目前仅为合作院校的老师提供该参考设计的源码。 Fri, 06 Jul 2012 13:51:10 GMT http://community.qnx.com/sf/go/post94125 Jin Xu 2012-07-06T13:51:10Z post94124: Re: 关于QNX CAR Project的连接问题 http://community.qnx.com/sf/go/post94124 QNX CAR 不是免费下载的产品,需要与我们的销售人员联系。 Fri, 06 Jul 2012 13:47:15 GMT http://community.qnx.com/sf/go/post94124 Jin Xu 2012-07-06T13:47:15Z post93237: 关于QNX CAR Project的连接问题 http://community.qnx.com/sf/go/post93237 在2009年的时候下载过QNX CAR的Project,现在公司又要进行这方面的研究了 但是连接已经无法使用了 http://community.qnx.com/sf/projects/qnx_car/ 现在有没有新的QNX CAR的Project可以提供下载阿?
