WARNING: Do not try to port or flash postmarketOS on the Watch if you don't have access to unbricking tools. You have been warned! |
- Familiarize yourself with the Unbricking Process (thanks to Arminas Keršys!)
- You will need a USB jig with the following pinout in case you brick:

Notes
- This device uses the same dzImage structure as other Tizen devices. See Samsung Z1 for more info.
- Apparently, the generic tizen_galileo_defconfig config has no display panel set by default. One has to use tizen_galileo_small/_large_defconfig or build will fail with panel and MIPI-related unused variables. User will have to choose which panel to use at build, like on the Xiaomi Poco F1 (one can NOT enable both panel variants at the same time, or the source will freak out)
Kernel Compilation Issues
- If using GCC 10 or newer, dtc-parser and dtc-lexer will fail due to -fno-common. This commit fixes it.
- NONE! Kernel builds properly.
Kernel Configs
- tizen_galileo_lte_defconfig - (USE ALONG WITH GALILEO-GENERIC AND 42MM/46MM CONFIGS) enables LTE functionality
- tizen_galileo_large_defconfig - (USE ALONG WITH GALILEO-GENERIC) enables display panel for 46mm variant
- tizen_galileo_small_defconfig - (USE ALONG WITH GALILEO-GENERIC) enables display panel for 42mm variant
- tizen_galileo_defconfig - TIZEN galileo-generic (USE AS BASE FOR ALL VARIANTS)
Notes
Samsung has not released SM-800 / SM-R805 (46mm / 46mm LTE) specific sources. Defconfig for them can be found in the SM-R810 / SM-815 (42mm, 42mm LTE) sources.
