Versions Used: Vivado, SDK & HLS 2018.2, ZC702 Rev 1.1 Win 7 SP1. The power system provides 1.0V, 1.5V, 0.75V, 1.8V, and 3.3V in 1.5 square inch solution. The order and ramp rates for each supply are programmed to accommodate Zynq-7000 AP SoC sequencing requirements. All power supply operations can be controlled over an I2C interface. Faults, output voltages and currents can also be monitored. Resource requirements for the AXI IIC core ha ve been estimated for 7 series and Zynq-7000 AP devices (Table 2-2). These values were generated using the Vivado® Design Suite. Note: Resources numbers for UltraScale architecture and Zynq-7000 AP devices are expected to be similar to 7 series device numbers. Virtex-7 –3 220 Kintex-7 220 Artix-7 160 To be able to examine the I2C and SPI interfaces between the Lepton and the Zynq, the Lepton has been placed on a breakout board with connectors between the Arty Z7 and the breakout board. This could affect signal integrity, however, both the I2C bus at 100 KHz and the SPI bus at 3.125 MHz have acceptable rise/fall times to prevent this from ...

The I2C controller specification v2.1 specifies the filtering out of glitches spanning a maximum of 50 ns on the SDA and SCL lines in the fast mode of operation. The I2C controller in Zynq-7000 SoCs PS7 does not implement the circuitry to filter these glitches. A glitch on the SDA or SCL line can cause a momentary false trigger on the signal line. A glitch on SDA could result in an incorrect ... Note: This example uses Digilent® Zybo Zynq-7000 ARM/FPGA SoC trainer board. This example does not work on Digilent® Zybo Z7: Zynq-7000 ARM/FPGA SoC development board which have two variants Zybo Z7-10 and Zybo Z7-20. To setup the ZYBO board, refer to the Set up the Zybo board section in the Define Custom Board and Reference Design for Zynq ... Dec 20, 2018 · The IOPs (e.g., USB, UART, I2C and so on) can interact with Zynq 7000 SoC via either MIOs or EMIOs. The processor system (PS) part of Zynq 7000 has many built-in IOP controller with each controller provides its own driver available in the form of C code, enabling the users to integrate the external IOPs with PS without any extra overhead. The power system provides 1.0V, 1.5V, 0.75V, 1.8V, and 3.3V in 1.5 square inch solution.

Faults, output voltages and currents can also be monitored. Mar 29, 2020 · Step 1: Enable the Zynq's SPI and I2C interfaces and route via EMIO to the appropriate pins of the Zynqberry's 40-pin header (J8). Step 2: Enable the I2C smbus and SPIdev kernel drivers in the PetaLinux project. Step 3: Create a GPIO function class library Python package for the Zynqberry. Hi, I have the Zybo Zynq 7000 board (Z-7010). I want to receive data from Multiple Devices via I2C protocol. In the PS there are 2 I2C Controllers. The Steps i made so far: 1) In vivado i created the ip : Zynq7 processing system. 2) iv enables the I2C 0 controller and routed it to Emio. at this p...

Zynq-7000 AP SoC, I2C - Missing I2C Master Completion Interrupt AR# 61665 Zynq-7000 AP SoC, I2C - I2C Missing Arbitration on Repeated Start AR# 60695 Zynq-7000 AP SoC, I2C - Standard Mode running faster than 90 kHz violates tHD; STA timing requirement AR# 59366 The standard driver for the Zynq PS I2C controller under PetaLinux is Cadence I2C_cadence which operates the PS I2C controller through its registers. Well the user level /dev/i2c0 writes were not working, so I added a custom module with the i2c_cadence as the basis and connected it to the I2C0 controller in the device tree to see how the driver ... The Flash connects to the Quad-SPI Flash controller of the Zynq-7000 PS via pins in MIO Bank 0/500 (specifically MIO[1:6,8]), as outlined in the Zynq Technical Reference Manual. Quad-SPI feedback mode is used, thus qspi_sclk_fb_out/MIO[8] is left to freely toggle and is connected only to a 20K pull-up resistor to 3.3V. Note: This example uses Digilent® Zybo Zynq-7000 ARM/FPGA SoC trainer board.
