关于Xilinx JTAG下载器

<div class='showpostmsg'>

现在Xilinx JTAG下载器 有两种方案1 Cypress方案，速度很慢
2 FDTI方案，Digilent推出来的，支持ISE 13+ & Vivado 速度支持10M/15M/30M
淘宝都有卖，第二种方案，淘宝竟然有卖200块以上的，其成本价 就是50元左右，不得不说暴利，而且只有JTAG功能
前段时间自己DIY了个，支持JTAG 和 UART，下载速度很快

基于FTDI 芯片的Xilinx JTAG 同时支持UART 电平1.8~5V



支持ISE和VIVADO

速度从10M、可以切换15M、30M

楼主DIY的有多余的卖吗？想收一个

STM32F103 发表于 2018-1-13 00:38

同问，楼主有多余的么？

白丁 发表于 2018-1-13 17:02

不知道仿真器下载器既然都是JTAG，为什么不能通用，altera的十几块钱，xilinx的便宜的也要一百出头，既然JTAG是个标准，为啥不能通用呢？
不知道楼主DIY的用不用自己写仿真器固件啊？

只DIY了2块，正在优化，优化后可以

目前Xilinx 和 Altera 理论上是可以通用，我正在做实验:)

淘宝上看过三合一的   XilinxAltera   Lattice隔壁论坛里记得也看过一个说三合一的也做成了

基本没什么固件
支持XIlinx
支持Altera（只测试了部分）

焊接厂不接单了，逻辑工程师自己焊接的

经过测试 全部OK

还没洗板，请忽略助焊剂

phdwong 发表于 2018-2-6 09:01

烧写工具
对于已经有的FTDI JTAG工具，慎用！
