Pocketbook Era and Inkpad 4 Kernels

enthdegree · 12-09-2024, 01:38 AM

Hello, it appears the Pocketbook Era (700) and Inkpad 4 (743) kernel sources haven't been published. See the repo where they're skipped over, with only configs for the Inkpad 3 (740), Inkpad X Pro (1040) and older:

https://github.com/pocketbook/kernel...ch/arm/configs

A cursory search suggests the source's only dependence on device model is 3 places: kernel config, sources for different device peripherals, and a button mapping here:
https://github.com/pocketbook/kernel...or/sc7a.c#L514

If I understand correctly,

for the devices we have source for, one is currently able to compile a kernel that's working, including screen and wireless, no binary blobs anywhere
there is precedent that Pocketbook publish the 700 and 743's kernels as they have the others

Are both these statements accurate? Looks like pocketbook has been good about publishing the source in the past. Does anyone know a likely way of getting them to do it again?

I asked for 618 source 3 times by email but they refused. I was able to build and boot that kernel with extracted defconfig, however there are binary blob kernel modules such as epdc.ko, ft6336.ko and ft6336.ko failed to load with my built kernel, so touchscreen did not work.

I got into U-Boot shell by typing many times CTRL C, 1, 2, enter, escape and other characters into uart while it was listening for power key presses to enter FEL. In shell there was a bunch of interrupts. There is USB Mass Storage some command that does it only for boot partition. Also do not use mmc command, emmc works but if you use mmc command it will stop, you can use fatload, fatls and probably more.
