首創(chuàng)ubuntu下cw32l031的vscode+gcc工程創(chuàng)建、下載、調(diào)試

目前官方提供CW32L083只提供了MDK、IAR下的固件庫(kù)、啟動(dòng)文件。我有過(guò)成功CW32L083的項(xiàng)目移植的經(jīng)驗(yàn)，現(xiàn)在成功的把CW32L031的工程移植到ubuntu下面，實(shí)現(xiàn)了VSCODE的GCC工程模版。現(xiàn)在將移植的過(guò)程與結(jié)果分享如下：

1. CW32L031與CW32L083同屬arm-cortex-M0+系列，通對(duì)比MDK下的啟動(dòng)匯編程序，發(fā)現(xiàn)除flsh與內(nèi)存大小不同之外，中斷、外設(shè)基本差不多。因此，我只需要修改。cw32L031、startup_cw32l031_gcc.s、CW32L031_FLASH.ld這三個(gè)文件就可以了。
2. 同時(shí)將相關(guān)的外設(shè)驅(qū)動(dòng)庫(kù)更換成cw32l031更換過(guò)來(lái)就實(shí)現(xiàn)了工程的移植。
3. 在ubuntu下面還需要安裝wch-link的驅(qū)動(dòng)。

3、移植好后，修改makefile的固件名稱、路徑就可以實(shí)現(xiàn)工程的編譯、下載、以及GDB調(diào)試。
