The Kit

The Ultra 96 boards has an Xilinx Zynq UltraScale+Tm MPSoC as the core. There are several Hard processors and peripherals. In addition to it, there is a considerable amount of programmable logic elements. Because it is required some devices to interface the programation and applications, there are some additional components to use in the Path to Programmable III.

All you need to make your own proyect was provided in this kit. The power requirements are meet using the corresponding power supply and there is not restrictions about your country, there is a cable for each standard.

Hello Engineer

I was using the Technical Training manuals, the one and two. There are some small differences but it were very precise to made the Hello world application. One of the first differences is the DRAM Bus Width. According to Vivado 2021.2, the LPDDR4 has a bus with of 32 bits while the manual only pictures the 16 bits width, for the DDR4 standard memory.

The code was modified as follows to calculate the number factorial and represents on the console. All was made on Windows 11 and the official Vivado 2021.2

#include <stdio.h>
#include "platform.h"
#include "xil_printf.h"
#include <stdint.h>

uint32_t f(uint8_t x);

int main(void){
	uint8_t x = 10;
	init_platform();
    print("Hello Engineer\n\r");
    xil_printf("%d! = %d\r\n", x, f(x));
    cleanup_platform();
    return 0;
}

uint32_t f(uint8_t x){
	uint32_t acc = 1;
	for(uint8_t i = 2; i <= x; i++){
		acc *= i;
	}
	return acc;
}

I recommend use this Vivado version since the 2023 brought me an unrecognized error, consequently, I uninstalled the last version an I was using the 2021 one. for the terminal you could use PuTTy and see the magic.

Conclusion

The Zynq Architecture is a very flexible platform to create Applications of Software, Hardware or both. There are interesting proposals using the wide mikroBUS modules, unfortunately, I will wait to do something with that. The next blogs going to improve the board usage. be careful if you want to update or change the structure since the screws are damaged from factory and are hard to unscrew. but be happy and enjoy the Zynq
