Error Flashing 4.0

[222Phoenix]

Just finished soldering the pcb & teensy 4.0 but I'm not able to flash it.

I tried the default one (kinesis_kint41_default.hex)
https://github.com/kinx-project/kint/tree/main/default-firmware
and also my own compiled via QMK MYSYS

I tried both teensy loader and QMK toolbox on different computers and different USB cables.

This is the error when trying to flash the default hex via QMK Toolbox:

*** Halfkay device connected (HidUsb): (Standard system devices) USB Input Device (16C0:0478:0108)
*** Attempting to flash, please don't remove device

teensy_loader_cli.exe -mmcu=atmega32u4 "C:\Users\admin\Desktop\kinesis_kint41_default.hex" -v
Teensy Loader, Command Line, Version 2.1
Warning, HEX parse error line 1
error reading intel hex file "C:\Users\admin\Desktop\kinesis_kint41_default.hex"

In #62, someone mentioned that flashing from Windows might have issues.

Can you try flashing from a computer running Linux? You can start your computer from a live linux USB stick.

Just tried in Ubuntu. I don't see an error, so it seems like it worked, but the keys still do nothing. Wonder if it's a bad Teensy. Flashing the LED blink program via Teensy loader did work though.

You can try the prebuilt firmware images on https://github.com/kinx-project/kint/ to see if it’s a problem with your build or with your teensy.

Teensy Loader won't flash the default firmware. In Verbose mode, opening the default firmware (kinesis_kint41_default.hex from
https://github.com/kinx-project/kint/tree/main/default-firmware) shows:

16:39:34.103 (loader): Verbose Info event
16:39:42.453 (loader): Open File event
16:39:45.391 (loader): ihex: parse error line 1
16:39:45.391 (loader): ihex: parse error line 2

The program button is grayed out. The status bar says: kinesis_kint41_default.hex (unreadable)

Sorry for the late reply.

I cannot reproduce this issue.

When I download the default firmware file, I can flash it without issues to a Teensy 4.1:

I’m strongly suspecting that the issue you’re running into is caused by how you downloaded the file. I suggest downloading the repository as a zip file from GitHub and then unpacking that.
