Hello, You are actually reducing the memory available to kernel by setting mem=80M. What you might want to do is to allocate memory using CMEM and use it instead of req_buf. Request buffer allocates memory from kernel memory space. Otherwise, use bigger kernel memory instead of reducing it. Murali Karicheri Software Design Engineer Texas Instruments Inc.

Hi everyone! I want to get a full resolution 5MP(2592x1944) picture from my MT9p031 sensor. but I failed when I req_buffers in the ipipe initialization procedure. I allocate a 80M memory to my linux in the bootargs(mem=80M),so I think there is a enough space for I allocate 1 5MP ipipe buffer from linux(which will require about 10M bytes),but when I execute the program, I only get the following errors: starting mt9p001_ipipe_init IPIPE idm355_ipipe dm355_ipipe.2: 4.request_buffer:not enough memory nit IPIPE_REQBUF fail IPIPE init fail what should I do to get the problem solved? any help will be appreciated! Thank you! 2008-09-02 ________________________________ Pavel Han Oplinx Co.,Ltd Address:Hanggang Fuchun Business Mansion 2116# Futian, Shenzhen 518041,PRC Tel: (086)0755-88359865 Website:www.oplinx.com.cn E-mail: [EMAIL PROTECTED]<mailto:[EMAIL PROTECTED]>
