lpc21isp(2)

　lpc21ispにデバッグモードがあるので、動きを見てみます。

VurtualBoxでは下記です。

./lpc21isp -debug3 -control -detectonly /dev/ttyUSB0 115200 12000
Turn on debug, level: 3.
Use RTS/DTR to control target state.
Only detect LPC chip part id.
lpc21isp version 1.83

ioctl get ok, status = 6
ioctl set ok, status = 6
ioctl get ok, status = 6
DTR (1), RTS (1)
ioctl get ok, status = 6
ioctl set ok, status = 4
ioctl get ok, status = 4
DTR (0), RTS (1)
ioctl get ok, status = 4
ioctl set ok, status = 0
ioctl get ok, status = 0

...続く...

　TPC-500ではMARY基板抜き差しで固まったり不安定です。
　しばらく同期出来ないなりに動いていたのですが、今はエラーで動きません。

Turn on debug, level: 3.
Use RTS/DTR to control target state.
Only detect LPC chip part id.
lpc21isp version 1.83
Can't open COM-Port 115200 ! (Error: 2d (0x2))

　動いて同期できないときは、確か?

　こんな感じだったと思います。

　IPLが"Synchronized+0Dh"を送信してきて、それに"?"で答えた後、さらに
Synchronizedで答えるのが、IPLの初期動作なはずです。VirtualBoxではそれなりに？進んでいます。
　IPLはコントロール端子を手動で操作すると(出来るとすると)ターミナルソフトで操作出来るみたいです。
　英語のビデオとかありますけど、ここが詳しいです。

　あくまでも、LinuxとMARY基板の通信が目的なので、じっくり調べます。
