We would need to know a bit more detail about 'not accepting the kernel' here. Has the kernel you built been configured correctly for your target board? Were there any traces from the serial console at the point of failure? How are you building for your target, are you using Yocto?, Buildroot?, or are you cross compiling the kernel yourself? Looking through some of your other mail postings, I see you are typing 'make -j4' but I can not see what environment you are building in. > i want to know "Is there any > special release of kernel for Renesas only? >From a community support perspective, you should really be looking to use the mainline. (An official release from kernel.org, or usage of torvalds/linux.git) If you are intending to make modifications to the sources, I would recommend that you use 'git', rather than downloading a specific version of source tree from kernel.org, as this will help you track the changes that you make. Are you familiar with git yet? You mention that you can not access github, but I see that you have been able to access kernel.org ... Are you able to 'clone' a git kernel using http? : git clone http://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git > if yes can you please > provide me some links or kernel from www.kernel.org are suitable for > all Renesas Board? Hopping your reply To answer that question as carefully as I can: The mainline kernel is suitable for all *currently supported* Renesas boards. For anything else you would need to contact the vendor specifically, or a specialist consultant to support you. > Best Regards Jithin T Raj -- Regards Kieran Bingham
