Hi,
I'm using O_DIRECT for write to SSD. It is working properly when the array is allocated in user space via malloc(). But when I try to use an array which allocated via Vsys_allocBuf() the write() return -1. Any suggestion? Or may be there is a way to organize DMA from a buffer a bufList of type VIDEO_FRAMEBUF_LIST_S to a buffer located in user space? I'm using DM8148 and ipnc_psp_04_04_00_01.Thanks,Constantin↧
