Himax WE-I: reset button doesn't register when I am attempting to connect

Help
#1

I’m using edge-impulse-cli on Windows to connect to the Himax. Here’s what I’m getting in the command prompt:

[HMX] Connecting to COM3...
[HMX] Connected, press the **RESET** button on your Himax WE-I now
[HMX] Error during update Failed to get a valid response (looking for "wake up evt:4") from device. Response was: ""
Press any key to continue . . .```

I have pressed the reset button a number of times, nothing happens. Has anyone had a similar issue? Could it just be a defective button?

Wondering if you’re up-to-date with the edge-impulse-cli? npm update -g edge-impulse-cli

Or perhaps it might be an issue with the bootloader. See: https://github.com/HimaxWiseEyePlus/bsp_tflu/tree/master/HIMAX_WE1_EVB_user_guide#himax-we1-evb-user-guide on how to update.

Thanks, I’ll try the bootloader piece over the weekend. I’ve definitely updated the cli.

Continuing the discussion from Himax WE-I: reset button doesn't register when I am attempting to connect:

I am looking at the link you sent for the boot loader. I have downloaded Tera Term. Instructions say to “please check xmodem protocol is supported” but when I go through the menu: File > Transfer > XMODEM > Send… it just opens a file explorer for Tera Term: XMODEM Send. I have no idea how to check if the protocol is supported, this is too vague.

So if I assume xmodem is supported, I followed the “Update Flash Image at Windows Environment” instructions. But when I open Tera Term and select File > New connection, the Himax WE1 is not listed.

Any idea of what I might be doing wrong?

@mmullen200 If you run edge-impulse-run-impulse --raw and reset the board do you see any messages from the bootloader? This is what it shows for me.

Hello from Edge Impulse Device SDK.

Have also pinged Himax.

When I hit the reset button, it just remains here, no further feedback

@mmullen200 In that case I think either your RESET button is broken, or the bootloader has disappeared (not sure if that’s possible) and I doubt that the board is recoverable… I pinged Himax over the weekend, maybe they have an idea.

FYI here’s feedback from Himax:

1.check if bootloader message displayed okay at tera-term
1.1 setting UART port via tera term, here is the setting
https://github.com/HimaxWiseEyePlus/bsp_tflu/tree/master/HIMAX_WE1_EVB_user_guide#serial-terminal-emulation-application-setting
1.2 check if bootloader version displayed.
https://github.com/HimaxWiseEyePlus/bsp_tflu/tree/master/HIMAX_WE1_EVB_user_guide#check-bootloader-version

if no message displayed or bootloader version display 1.4.2, go to step 2

  1. update bootloader at Linux environment
    2.1 Ft4222 linux driver is needed to update the bootloader, please follow the link to update

Thanks so much for looking into this, much appreciated. I really wonder if it might be a broken button, but I will dig into these instructions.

Received a new device, it was definitely a broken reset button on previous one. Thanks for all your help.
