不過說除了用 Arduino IDE 之外，也可以用 Standard SDK.
然後就是說參考： 就 follow Project README： clone , untar tools， export PATH.
然後就可以開始 build example 了。
因為 build 最後的 tool 有分 linux 版的 *.linux 和 windows 版的 *.exe。
這個 repo 的 linux file attibute 沒有設定對，build 的時候會出現 Error。
所以先去把所有的 *.linux 加上 execution.
開始 build..
cd ambpro2_sdk/project/realtek_amebapro2_v0_example/GCC-RELEASE/build/ cmake .. -G"Unix Makefiles" -DCMAKE_TOOLCHAIN_FILE=../toolchain.cmake -DVIDEO_EXAMPLE=ON cmake --build . --target flash_nn -j4build 完，會是剛剛 --target 寫的 flash_nn.bin
燒錄是 tools/Pro2_PG_tool，把 zip 解開。把剛剛build 好的 flash_nn.bin copy 過來。
和用 Arduino IDE 一樣， HUB 8735 進入 download mode:
- 短路 A5, 3V3 pin
- 按一下 reset buuton
README 的說明 -b 2000000，會出現 ucf fail，看 ./uartfwburn.linux --help， -b 是 baudrate 的意思。
所以改成 9612000 後成功：
~/ambpro2_sdk/tools/Pro2_PG_tool _v1.3.0$ ./uartfwburn.linux -p /dev/ttyUSB0 -f flash_ntz.nn.bin -b 921600 -U /dev/ttyUSB0 opened ping ok ucfg ok Uart boot programing [========================================] 100% 77824/ 77824 bytes programing done. uboot ok reset device /dev/ttyUSB0 opened ping ok ucfg ok download to offset 0x0 masked area [0x0, 0x0] dowload 0, [0x0, 0xd9e000] fw_len = 0xd9e000 programing [========================================] 100% 14286848/ 14286848 bytes programing done. done for download 0 download success然後把 A5. 3V3 短路 pin 解開。reset
用 uart 115200 看到開機 log:
