Dear Kris：

Hi, it's me Kevin again. Recently, I'm try to run example of Smart Agriculture with using WE-I (DSI_6537). I had followed the step in "SmartAgriculture-example". But I'm stuck in last step.

The last step said use Himax Flash Tool to flash the out.img in image_gen_linux folder with command himax-flash-tool --(firmware-path)/image_gen_linux/out.img.

So I put my path which image_gen_linux folder is like this : himax-flash-tool --/home/bcrkevin/Documents/DSI_6537/Example/WE_I_Plus_User_Examples/SmartAgriculture-example/image_gen_linux/out.img. But it's not work.

And I also found similar command himax-flash-tool --firmware-path image_gen_linux/out.img in "running-your-impulse-himax".

I was wondering, What the correct "firmware-path" should I fill in. Thank you.

@kevin789654tw hi

  1. list your USB com number 
    ls /sys/bus/usb-serial/devices/ -ltra
  2. In my case the WE-I is on /dev/ttyUSB0 
    sudo chmod 777 /dev/ttyUSB0
  3. Flashing You'll need to install the Edge Impulse CLI. Reference here https://docs.edgeimpulse.com/docs/edge-impulse-cli/cli-installation . Go under the folder you generated the out.img file 
    himax-flash-tool -f out.img

Hi, Kris：

My USB com number : Screenshot from 2022-06-23 23-19-21

I flashed my WE-I like this : Screenshot from 2022-06-23 23-23-10

But in my minicom shows that nothing can run : Screenshot from 2022-06-23 23-31-29

I've wrote some notes. Here are my steps and reference URLs: https://hackmd.io/@kevin789654tw/BJahFUWcq

Also, I was wondering, is there something wrong with my model creation? Here is my project in Edge Impulse. https://studio.edgeimpulse.com/public/114087/latest

@kevin789654tw hi It seems like that your ccs811 initial fail. Make sure that you follow the Prerequisite https://github.com/HimaxWiseEyePlus/WE_I_Plus_User_Examples/tree/main/SmartAgriculture-example#prerequisites to install SparkFun Environmental Combo Breakout - CCS811/BME280 (Qwiic) and LoRa - REYAX RYLR896 on WE-I.

Thank you, Kris. I misunderstood that SmartAgriculture-example can do without setting SparkFun Environment and LoRa. I'm totally wrong. Thanks for helping me out.
