[dace] TicWatch Pro 5 support

[argosphil]

I think this would make for an interesting target as it has the new Qualcomm SW5100+ chipset, 2 GB of RAM and 32 GB of flash. However, I've contacted Mobvoi and they don't want to release the kernel source code, so there's no way to get at the device identifiers necessary to create a fastboot image that won't be rejected right away.

Things that would be interesting:

• /proc/cpuinfo, if accessible
• /proc/config.gz, if accessible
• anything readable in the /sys/devices/ subdirectory
• rooting the watch in Android would also be good, but I understand it's unlikely to happen?

Here are the things asked:

• /proc/config.gz
• /proc/cpuinfo
• /sys/devices/ but nothing is readable without root permission.

Don't they simply have to, as the Linux kernel is GPL-2.0 licensed?

[Fuseteam]

they do yeah

@argosphil

I contacted mobvoi support, and it turned out that their source code had been published a long time ago!

See https://github.com/mobvoi/mobvoi-ticwatch-kernel

uranus_kernal branch is pro 5
mobvoi-android-msm-rover-4.9 is pro 3 series

P.S. I'm far from being an expert on linux/android and won't be able to answer your questions. Just forwarding information from mobvoi

[stone-w4tch3r]

Also since kernel for 3 pro is available, is it possible to support those watches too? I can help with testing etc

[Fuseteam]

@stone-w4tch3r does this mean the ticwatch Pro 5, Enduro and Atlas all use the same kernel? (they all seem to be mostly the same afaict....tho not sure about the SoC atm)

[stone-w4tch3r]

@Fuseteam being honest, idk. But since series 3 share one kernel, I suppose this is possible for series 5 too
