Linux 15 周年！嵌入式系統的挑戰？

chip123

你知不知道 Linux 15 周年了！回想從1991年的8月25日正是 Linux 的誕生日起，Linux 深遠地改變了世界資訊技術的運行格局，並一手促成了開放源始碼軟體，以及如今當紅的 Linux 嵌入式系統的發展 。

你有在開發 Linux-based 嵌入式系統吧？現在比較流行的 Linux 硬體平台有Intel公司的StrongARM 系列、Motorola公司的DragonBall系列、NEC公司的VR系列、Hitachi公司的SH3、SH4系列等等。選定硬體平台前，首先要確定系統的應用功能和所需要的速度，並制定好外接設備和介面標準。這樣才能準確地定位所需要的硬體方案，得到性價比最高的系統!?

回想 Linus 創始者 Torvalds Linus 在發佈 Linux 的當時說了些什麼呢？讓我們來做一個回顧：

"Hello everybody out there using minix -

I'm doing a (free) operating system (just a hobby, won't be big and professional like gnu) for 386(486) AT clones. This has been brewing since April, and is starting to get ready. I'd like any feedback on things people like/dislike in minix, as my OS resembles it somewhat (same physical layout of the file-system (due to practical reasons) among other things).

I've currently ported bash(1.08) and gcc(1.40), and things seem to work. This implies that I'll get something practical within a few months, and I'd like to know what features most people would want. Any suggestions are welcome, but I won't promise I'll implement them :-)

PS. Yes - it's free of any minix code, and it has a multi-threaded fs. It is NOT portable (uses 386 task switching etc), and it probably never will support anything other than AT-harddisks, as that's all I have :-(."

要良好的開發環境很重要押
