## 重要變革

## 開發進度

AjMaChInE
* [FPGA-accelerated TrustZone-enabled IOTA Swarm Nodes](https://hackmd.io/aYrpgwSrRyWcgr74Zpv7aA)
* 這周完成
* iota-swarm-node可正確跑在Arrow Sockit board上。
* pyOTA 2.0.5 -> pyOTA 2.0.6
* LampaLab建置的linux環境沒有curl，必須額外安裝curl。
* python 2.7.13
* 把LampaLab pow中的software部分整合進dcurl，可產生出 libdcurl.so，但使用iota-swarm-node的make check無法正確驗證。
* [error message](https://hackmd.io/blMdDCDzTCqLKXMmfHmfDw?view#error-message1)
* dcurl的sse編譯問題
* [dcurl makefile](https://github.com/ajblane/dcurl/commit/0100646d2d101bb7142e33996c4ffe6ed6a53c49#diff-b67911656ef5d18c4ae36cb6741b7965R33)

* 編譯dcurl時的warning message，libdcurl.so還是有產生。

...
Makefile:135: "skip build/test-multi_pow_cpu because PyIOTA is not installed."
...

原因: pip install pyota 預設會安裝在python 2.7.13下，而[dcurl/mk/python.mk](https://github.com/ajblane/dcurl/blob/dev/mk/python.mk)是檢查python 3有無安裝pyota。由於iota-swarn-node是使用python 2是否改成檢查python 2?

* 下周
* 2 issues
* 解整合上bug
* 建構optee on Rpi3

### Cross compiling問題: shufps 為例

Cross compiling問題: shufps 為例，在使用make BUILD_FPGA=1且有SSE環境下，只會編譯到ENABLE_SSE的區域，不會編譯到ENABLE_FPGA區域
* make BUILD_FPGA=1
* cc -o build/dcurl.o -Wall -fPIC -Ofast -msse2 -DENABLE_SSE -DENABLE_FPGA -c -MMD -MF build/dcurl.o.d src/dcurl.c
* [ENABLE_FPGA](https://github.com/shufps/dcurl/blob/dev/src/dcurl.c#L99)

...
#elif defined(ENABLE_SSE)
ret &= pow_sse_init(MAX_CPU_THREAD);
#elif defined(ENABLE_FPGA)
ret &= pow_fpga_init();
...
