SPI Controller WorkflowThe SPI Controller provides 2 SPI interfaces. Each SPI interface has two channels, the TX channel and the RX channel, respectively. The CPU writes the data to the FIFO, writes the data to the Spi_tx_data register, so that the contents of this register are automatically moved to the sending FIFO, and if the CPU is going to read the data from the receiving FIFO, it accesses the register spi_rx_data, The data that receives the FIFO is then automatically moved to the Spi_rx_da

EmbeddedLinux Bare Metal Development (11)--nandflash First, about Nand Flash nand f lash Yes flash, has the advantages of large capacity, fast rewriting speed, and is suitable for storing large amounts of data n and flash no special address line , send instructions The address and data are all via a 8/16-bit wide bus (I/O interface) to the internal register. Nandflash is divided into SLC

think we have to explore other solutions in other directions. Openshift -Openshift can create kubernetes clusters, but we don't like to be tied too tightly to the vendor's solution in the critical infrastructure segment, and don't want to assume the risk of future technology locking. Kops -We are a loyal fan of Kops and we use it to deploy our cloud "Control Panel" Kubernetes cluster. Unfortunately, when we use it in

I have been using Ubuntu for two years. From dapper-6.06 to the current hard-8.04 (it took only one month ). At the beginning, I felt that Linux technology was booming. Progress is very slow after a period of time. I think I am a beginner at the cainiao level. I also think Ubuntu masks many Linux things. I only use its shell, and then press the mouse to beat my life. . In addition, you don't even need to execute commands to use Ubuntu to install everything you have just created. Later, I learned
