[bug] Crowview Note V1.1: endpoint stalled

[niansa]

Hi!

I'm trying to read the firmware of the sh68f83 controlling the keyboard/mouse inside the Crowview Note (v1.1), but all I'm getting is:

Hey, I can't find anything online about this device. Can you tell me how do you know the keyboard runs on a sh68f83? Do you have pictures of the IC, maybe?

[niansa]

Yup, here you go!

On the right hand side you can see the keyboard connctor, and the I2C trackpad connector on the other.

Can you try reading using this branch: #159 ? I believe the bootloader found on this device is a little different and I just now noticed that it's the same IC that the pinebook pro uses

[niansa]

Nope! No success. I'm always either getting:
