Kobo Forma device IDs

[geek1011]

I've been looking at the firmware, and noticed two IDs for the forma: 377 and 380. I think they are for the different storage sizes. Can someone with the 8GB and someone with the 32GB Forma post their device ID (it's in .kobo/version) so I can make sure I know which one is which?

I've got a 32gb Forma and the version ID shows 380. If you need the entire string, I can provide that.

Device::getClassString(). I'm working on putting together a big list of all the possible devices, as I'm tired of looking for it every time I need it: the codename, the device, the device name, the sub-device ids, the sub-device name additions, the amount of storage, the amount of memory, the difference in serial numbers, the hardware version, and the PCB id (and maybe a bit more). I'm currently piecing this together from the functions under Device, iMX508, and a few other classes.

OK, thanks. Now waiting for someone with the 8GB, although I am 99% sure that's what the 377 is.

I have the 8gb Forma and the Device ID ends in 377 (preceded by a whole bunch of zeros).

OK, thanks. That's all I need to know.

Here's what I have so far:

On a mildly related notes:

The purely HW-specific bits (CPU, RAM, etc.) are in the NTX HWConfig tag found in a clump of bytes at the start of the block device.

You can decode the data on your own device via ntx_hwconfig, or you can implement the bits you need yourself to avoid calling that thing (it appears to be statically linked against the glibc, brr!).

Various generations of Kobo kernels source packages have more or less detailed info in the related header. Earlier kernels were messy, but a bit more verbose.
