HFLink
About the HFLink PCB
HFLink is an open source PCB design by LX050724, published on GitHub under the Apache-2.0 license. It is a 4-layer board measuring 48.5 × 33.5 mm, with 111 components from 31 distinct parts.
Other key parts include the ECMF02-2AMX6, USB3320C-EZK, SN74LVC1G125DCK, SN74LVC2T45DCUR and MT9700. By type, the board carries 48 resistors, 33 capacitors, 15 ICs, 6 connectors, 4 inductors and 3 diodes.
From the project
完全使用FPGA实现的高速DAP
- 默认模式 1. 红色：目标电压低 2. 绿色：目标电压正常 3. 黄色：复位信号低 4. 熄灭/不规律闪烁：DAP正在执行命令，熄灭时间表示执行时间 - CMSIS-DAP模式 1. 绿色：空闲 2. 蓝色：已连接 3. 紫色：运行中
Manchester支持大容差无需小数分频，波特率计算公式200M/n (n>=2)
- VTRG电压&5V电流读取 ⬅️需开发上位机 - SPI ⬅️需开发上位机 - 线路延迟自标定⬅️需开发上位机
1. 打开高云FPGA工程，调整include路径配置 2. 重新生成M1 IP核，其他IP核不需要生成 3. 综合生成FPGA比特流 4. 编译MCU代码自动生成合并MCU程序的比特流文件bitstream.bin 5. 高云下载器设置Debugging/Temporary Mode -> Set ExFlash QE For Arora V使能Flash的Quad模式（仅需一次） 6. 高云下载器设置External Flash Mode Arora V -> exFlash Erase,Program,Verify Arora V进行外部Flash下载
