Zynq transplant ucosiii

   I refer to B Video on the station 《FPGA(ZYNQ) Up operation UC/OS Example -TCP Communications 》, In their own ZYNQ Porting on Development Board uCOSIII operating system , To configure BSP, Some steps are recorded here .
Software ：Vivado 2017.4
chip ：xc7z010clg400-1

Hardware design

First step ： newly build Vivado engineering , establish Block Design, stay Block Design Add ZYNQ7 Processing System IP nucleus .
The second step ： To configure ZYNQ7 Processing System IP nucleus .
   To configure PS Of UART, Click on Peripheral I/O Pins page , choice UART1, My board leads to MIO48 and MIO49, The baud rate is set to 115200.
   To configure PS Of Ethernet, Click on Peripheral I/O Pins page , choice Ethernet0, My board is used PHY The chip is RTL8211E,Ethernet0 What leads out is MIO16~MIO27,MDC and MDIO Assigned to MIO52、MIO53.
  MIO Configuration The setting of the page is shown in the following figure .
   Finally, put all the rest GPIO MIO Choose , For other purposes （ Lighting ）.DDR3、PS The clock 、 Interrupt and other configurations are based on your own needs , It's not recorded here . Configured Block Design As shown in the figure below .
The third step ： Verify the current design , Generate top level HDL modular , Export hardware , start-up SDK.

software design

First step ： download uCOSIII Code .
   You can download it from the website of the beginning video . website ：https://github.com/suisuisi/zynq_guide/tree/main/ucos. This is the company that develops the operating system for ZYNQ Of Cortex-A9 CPU Transplanted code , We don't need to make any changes , Just in SDK Configure it in .
The second step ： stay SDK Import uCOSIII Code .
   Unzip the downloaded compressed package , take uCOSIII Put the code folder under your project directory .
   Click on SDK Above the software Xilinx->Repositories, stay Local Repositories Import in column uCOSIII The path of the code folder , Click on “OK”.
The third step ： New application .
  OS Platform choice ucos, Click on “Next”. On the next page, select Micrium uc/OS-III Hello World Templates .（ Other templates can also be tried ）.
Step four ： To configure BSP.
   Right click on the left ucos_base_bsp, Click on Board Support Package Settings, Open configuration BSP The interface of .
  Ovrview Click the following figure to check the module , I chose three modules that I must have , Check other modules as needed . among ucos_standalone Modules allow us to use Xilinx Provided peripheral driver code .
   stay ucos_standalone in , take stdin and stdout Set to ps7_uart_1, That is what we selected in the hardware design UART1.
   stay drivers in , take ps7_ethernet_0 The driver of is ucos_emacps, Save it for network experiments （ This article does not cover ）. Step five ： Write code .
  ucos_base->src->app.c There is automatically generated code in , You can compile and download it directly to the board for experiments .

#include <stdio.h>
#include <Source/os.h>
#include <ucos_bsp.h>
void  MainTask (void *p_arg);
int main()
{
    
    UCOSStartup(MainTask);
    return 0;
}
void  MainTask (void *p_arg)
{
    
    OS_ERR       os_err;
    UCOS_Print ("Hello world from the main task\r\n");
    while (DEF_TRUE) {
    
        OSTimeDlyHMSM(0, 0, 10, 0, OS_OPT_TIME_HMSM_STRICT, &os_err);
        UCOS_Print("Periodic output every 10 seconds from the main task\r\n");
    }
}

I also tried TCP and DNS The template of , The development board connects to the router , Can succeed in IP Address .
