question about the PC TOOL #6

Dear Kris：

Hi, my name is Kevin. I've a question in using WE-I (DSI_6537), which is I can't show detect results by the PC TOOL. It doesn't have any responds. I like to know which step I got wrong. This is the step I did on my linux ubuntu 20.04. Thank you.

-->

  1. Download and install FT4222 Linux driver (https://www.ftdichip.com/Support/SoftwareExamples/libft4222-linux-1.4.4.9.tg z)

  2. cd into "libft4222-linux-1.4.4.9"

  3. tar xfvz libft4222-1.4.4.9.tgz

  4. sudo ./install4222.sh

  5. cd into "examples"

  6. cc get-version.c -lft4222 -Wl,-rpath,/usr/local/lib

  7. sudo ./a.out (Terminal show --> Chip version: 42220400, LibFT4222 version: 01040409)

  8. cd /etc/udev/rules.d/

  9. vim 99-ftdi.rules ( What I type : # FTDI's ft4222 USB-I2C AdapterSUBSYSTEM=="usb", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="601c", GROUP="plugdev", MODE="0666" )

  10. cd into "my folder" (where I put the PC TOOL)

  11. chmod 777 PC_TOOL_Linux

  12. Then I click PC_TOOL_Linux, and click Recv

@kevin789654tw hi

  1. Check your 99-ftdi.rules. Because you say that you type ( # FTDI's ft4222 USB-I2C AdapterSUBSYSTEM=="usb", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="601c", GROUP="plugdev", MODE="0666" ), it may be commented out the rule. You should type two lines which like the below example.

    FTDI's ft4222 USB-I2C Adapter

    SUBSYSTEM=="usb", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="601c", GROUP="plugdev", MODE="0666"

  2. Make sure that you had sent the image by SPI at your WE-I code.
