+# TODO list
+
+## General
+
+### New families
+
+- BL602
+- RTL8710A
+- RTL8720C
+- RTL8720D
+- W600 and/or W800
+- LN8825
+- host-native family
+
+### Tools
+
+- move all UF2 assembling/uploading/processing tools (as well as `uf2ota` C library) to a separate repository, possibly rewriting parts of it again. Make these tools CLI-usable
+- write OpenOCD flashers, using uf2ota library + FAL for partitions (same repo as above)
+
+### Serial
+
+- configuration of RX/TX pins
+- SoftwareSerial library - receiving + Beken family
+
+### Other
+
+- watchdog API
+- `Preferences` library
+- test/fix IPv6 on different families
+- what is `PowerManagement` at all? probably useless -> remove
+
+## BK7231
+
+- WiFi events
+- implement OTA
+- fix WiFi on BK7231N, test other functionality
+- add generic board definition
+- fix SSL (mbedTLS)
+- I2C (Wire)
+- SPI
+- BLE
+
+## RTL8710B
+
+- add generic board definition
+- move to GNU++11 (and verify that it works) - take all stdio functions from stdio.h
+- rewrite most of Wiring (it was copied from `ambd_arduino`, and is ugly)

+
+Bootloader and app partitions contain CRC16 sums every 32 bytes. That results in the actual flash offsets/sizes not aligned to sector boundaries. To simplify calculations, the values shown in the table (extracted from bootloader's partition table) were aligned to 4096 bytes.

+
+Bootloader and app partitions contain CRC16 sums every 32 bytes. That results in the actual flash offsets/sizes not aligned to sector boundaries. To simplify calculations, the values shown in the table (extracted from bootloader's partition table) were aligned to 4096 bytes.
