Hi.I use zynqMP on my custom board. I have to use 26 PL AXI UART IP in my project with linux (vivado 2019.1 and petalinux 2019.1). ZynqMP support just 16 PL-PS interrupt. I need use axi interrupt controller IP in my design to
PL will write a value of the last four bytes of buf, and the ps side will write the last four bytes of buf as 0 every time the ps side reads buf. The problem is that when ps obtain buf3,it occasionally reads out the last four byte values of 0, but the pl terminal has written ...

zynq7000系列拥有共计最多118个gpio的引脚控制(理论上ps+pl),其中MIO 54个,EMIO64个,其trm的框图如下 zynqmp系列同样如下 其MIO 78 EMIO 96 其trm的框图如下 此外zynq还可以通过AXI总线进行GPIO的扩展 在vivado的框图上如下所示,这里用的是7020 的器件,zynqmp与其相似 接下来详细叙述 如何使用 这里还是以7020为...

ISSUE:My system does not always boot. If I program only the FSBL \+ FPGA (PL) the FPGA boots with no FW. I got both FW running with linker script of the FSBL set to OCM and RPU FW 1 \+ 2 linker script running on the two ATCMs. Then I modified the PL (...

Mixed Audio to PL The Buffer Manager interacts with external interface such as DMA engines or live audio/video streams from the programmable logic. The Video Rendering Pipeline blends the video and graphics layers and performs colorspace conversion. The Audio Mixer mixes the incoming audio streams....
