Tapo H500

Spec

SoC: SigmaStar SSR920G

DRAM: 128 MiB

eMMC: 14.6 GiB (from kprintf)

Baudrate: 115200

好きな rootfs で起動させる方法

1. 分解する

2. UART を引き出す

基板裏のシールド右下にある

TX と RX は直列の 0Ω が unmount されているので、0Ω 上側のランドに直接はんだ付けするか、はんだでブリッジさせてから TP7, TP8 に結線する

https://gyazo.com/b99eeb62f8011f87bb4c44036f4a03e2

3. UART を PC で開く

4. 電源コネクタを接続して電源を入れ、その瞬間に eMMC の信号が流れる抵抗と周囲の銀色のシールド間をピンセットでつまんで eMMC の読み取り動作を壊す（下図）

5. U-Boot がエラーにより shell に fallback する
