Solved: hi Team, i want to implement DMA for memory to peripheral application using UART. i want to understand how to select transfer type for this
dma_1: memory to periheral read_master: sdram中的数组的地址 write_master: uart txdtxddata地址 (2)uart ip 定制 (3) dma ip 定制 根据dma 的ds,至少得read_master 两倍的深度,不然会出错(此处准备1024,故增大一位11:bit) 次数是数据寄存器的长度,即数量,不是宽度。 下面是dma ip定制的允许传输的字...

Hi, list Besides kmalloc() is more efficient, are there some potential problems that I should be aware of if I allocate the memory which doesn't have any relation to peripheral hardwares(i.e. DMA,PCI,serial port and etc) by vmalloc() instead of kmalloc() to avoid the page allocation ...
