My keyboard is misbehaving and I wanted to make sure the firmware was intact. I ordered a replacement keyboard and the IVR-ISP500-TINY, and I thought I'd look into practicing with the replacement, maybe see if there was a way to dump the factory image. But I don't see anywhere to connect the programmer to the keyboard.
Could you advise me how to do this, or where to learn? I'm worried I could break the keyboard opening it.
It is the ICSP0 pads (if you purchased TERES-PCB5-KEYBOARD). You attach a connector temporarily the connector should be male-male 2 rows x 3 pins at 0.1" step.

Thanks so much. I forgot about the separate keyboard controller board. I've affixed a 2x3 header to my programmer.
Your link: I'm guessing it's for updating the firmware from the same Teres system, not via a programmer? It looks like it uses an "hid_bootloader_cli" binary to do the upload. Do you know where the source for this binary is? EDIT: I found that this binary is from lufa and the source is in lufa =)
Thanks so much.
The hex binary and the command to use can be found here:
Thanks again. I reflashed my chip successfully. It looks like the system needs to be powered on when flashing or you get an obscure avrdude error that appears related to low current. I submitted a PR adding more information from my experience to that subfolder.
It's great to be able to verify the firmware in my keyboard. I cut a hole through the bottom of the system to access the pins more easily in the future. I've noticed the firmware changes some of its content when running. I haven't looked at the source yet.
Thank you again.
