【XR806開發板試用】全網首發,對接騰訊云平臺的血淚史

1.前面的話

在上次連夜肝出了華為云平臺的帖子:https://aijishu.com/a/1060000000287434
之后,論壇里的反響平平,好評沒有,點贊更無,抱著已完成任務成功白嫖一塊板子的心態,把板子收在了盒子里,第二天,助手小姐姐跟我說為何不把騰訊云的做了,對于這個要求我其實是拒絕的,但是小助手姐姐說寫的好的話,會有獎勵,當時我就笑了,把我當什么人了,我缺你的獎勵嗎,我現在就想問一句:什么時候能發貨?

之所以要對接騰訊云其實是覺得騰訊云真的蠻好的(這句話不要寫,包括括號),雖然本人跟騰訊沒有一毛錢的關系,甚至曾找大佬內推簡歷后面換來一句已經招到了的回答,但是依然不能因此就否定它,他那清晰的文檔,優雅的sdk代碼,使我不能抗拒.
好了,說一點小笑話,調節一下氣氛,進入正題

2.好戲開場了

按照上一篇對接華為云的套路,我們首先來找官方sdk,茫茫文檔中給我看到了那熟悉的身影:

文檔地址在這,拿走不謝:
https://cloud.tencent.com/document/product/1081/48356
把sdk下載之后,熟練的放進thirdparty文件夾,這個時候依然要看文檔,因為有些函數需要自己實現,具體是哪些呢,在這里:
https://cloud.tencent.com/document/product/1081/48389
這篇文檔寫了,我們要實現里面的這些接口,此處列舉一二:

仔細一看,霍,好家伙還不少呢,但是不怕,都是打工人,誰怕誰啊,二話不說我就寫,結果就給我給寫出來了:

,寫出來這些后就可以準備編譯了嗎?
nonono,我們還沒做BUILD.gn文件呢,話不多說,直接教你寫:

}

整完之后就可以嘗試一下有沒有錯誤了.

3.在main里面寫邏輯,處理事情

我們把官方sdk里面的點燈demo拿過來,直接新建一個demo文件夾,把文件放進去:

自己寫好BUILD.gn,跟之前華為云對接一個套路噻,大家這么聰明,不用我多說了
然后在sample里面的sdk把這個文件夾開啟編譯:

這樣就完成了代碼的編寫了,是不是很快樂呀

4.開始編譯(血與淚的旅程)

4.1首先出場的是UTILS_LIST

這個utils_list.h不能被系統識別的問題還真是頭疼,經過兩小時+的奮戰,被我發現系統也有一個utils_list.h錯誤(忘了截圖了),這就有點不講武德了,竟然與代碼的友好協商,我這樣改:

終于把這個小家伙趕走了

4.2 緊跟著MBEDTILS當然不讓,是迎頭痛擊

編譯出來有個mbedtls的錯誤(依然忘了截圖),后面分析出來是某些編譯宏沒搞對吧,然后我一番查找,就把qcloud里面帶的mbedtls里面的config.h拷貝出去,放到系統自帶的mbedtls里面:

結果,當然是沒用了,這我就納悶了,難道系統的mbedtls庫是提前編好的,不能更改了,帶著這個疑問,我就翻遍了系統自帶的文件,結果被我找到一個東西:

在device/xradio/xr806/xr_skylark/src/net/mbedtls-2.16.8這里有一個mbedtls的源碼,這下我就坐不住了,趕緊看看這個源碼有沒有參與編譯,結果終于被我發現端倪,

這里指定了一個變量叫做MBEDTLS_CONFIG_FILE,我就說我怎么老看到mbedtls有這種代碼:

yes, 就說他了,說明他把config文件定向到了一個叫做<config-xr-mini-cliserv.h>這個文件了, 那可就方便了,我改吧device/xradio/xr806/xr_skylark/include/net/mbedtls-2.16.8/mbedtls/configs/config-xr-mini-cliserv.h
終于是把mbedtls的錯誤給整好了,花了我又是2h+,我只想問人的一生有幾個2h不說了,繼續編譯,這里需要注意的是,因為我們改的是系統的lib,所以需要在device/xradio/xr806/xr_skylark$,目錄執行 make lib -j,讓系統重新生成庫

4.3 內存不足讓我心如死灰

終于是把兩個大的攔路虎給搞定了,真開心,雖然時間已經晚上10點多了我可一點都不困喲,想著馬上就可以大功告成贏取助手小姐姐
咳咳,呃,親手發送的禮品了,迫不及待得編譯,運行,結果剛上來就是悶頭一棍,
執行wifi掃描都內存不:
, 雖然我知道這mbedtls費內存但也不至于到這步田地吧,連wifi掃描都不讓那板子不廢了嘛,苦于對芯片不熟,內存方面的資料是一點沒有,于是我當機立斷在論壇里面發帖控訴為什么只有這么一點內存:
https://bbs.aw-ol.com/topic/854/wifi掃描提示內存不足-288kb可用的有多少?_=1640440348789
想著第二天應該有人解答吧,結果等今天下午一看,沒人理我,想了一下,小姐姐這么熱情的邀請我把騰訊云對接出來,我得兌現我的承諾呀,繼續磕吧.
突然我想到了我這個工程是官方的一個叫wlan_ble的proect上面弄個,會不會是ble藍牙占了內存呀,因為是sram運行,會把code也給拷過來嘛
想到這里,我的毛孔全部都舒張起來了,一股頭皮發麻的感覺涌上腳心,這就弄.于是我不慌不忙的就把ble給禁了,在device/xradio/xr806/xr_skylark$目錄執行make menuconfig:

小子還想陰我老人家,昨天是我大意了,沒有閃,這招就送你下去.
弄起來一跑,爽歪歪
