【風(fēng)火輪YY3568開發(fā)板免費(fèi)體驗(yàn)】第一章：開發(fā)環(huán)境搭建，系統(tǒng)替換為原生Linux
第一章：YY3568 內(nèi)核開發(fā)環(huán)境搭建
本章主要記錄如何替換 YY3568 出廠的安卓系統(tǒng)（開發(fā)起來(lái)有點(diǎn)不純粹，我更習(xí)慣在原生的Linux上進(jìn)行開發(fā)）。在替換系統(tǒng)的過(guò)程中，有一些要點(diǎn)和經(jīng)驗(yàn)做一些記錄：
- YY3568 的 UART2 是 UART DEBUG。波特率為1500000
- 使用 Loader 模式分區(qū)燒寫鏡像，涉及到使用parameter.txt查看分區(qū)信息，在Loader模式中根據(jù)這些分區(qū)信息進(jìn)行燒寫
- 在 Debian源碼中分別編譯kernel,uboot以及buildroot對(duì)應(yīng)的根文件系統(tǒng)
- 在使用 buildroot 編譯根文件系統(tǒng)的時(shí)候，出現(xiàn)了 su 命令切換 root 提示錯(cuò)誤的問(wèn)題，通過(guò)修改 buildroot 打包根文件系統(tǒng)的過(guò)程手動(dòng)打包出來(lái)rootfs規(guī)避了這個(gè)問(wèn)題。這里還簡(jiǎn)單描述下https://youyeetoo.cn/thread-6228-1-1.html
1. 獲取源碼，編譯
本次編譯我使用的是在一臺(tái) Fedora35 的 PC機(jī)上編譯 debian10 的源碼，相關(guān)資料在風(fēng)火輪的wiki中都有體現(xiàn)，具體鏈接是https://pan.baidu.com/s/1NynxVL6VnqPBSOVkRu8J7Q?pwd=t6cg
下載下來(lái)后根據(jù)編譯方法進(jìn)行編譯就行了，我選擇的是分別編譯uboot,kernel和rootfs(buildroot)。具體流程是：
# 解壓
cat YY3568-Debian10.tar.gz.0* | tar -xzv
cd YY3568-Debian10
git reset --hard HEAD
#編譯
./build.sh YY3568-Debian10.mk
#./build.sh 這一步我沒(méi)有執(zhí)行，因?yàn)槲覔?dān)心編譯太耗時(shí)
./build.sh uboot # 比較流暢，主要修改了幾個(gè)配置，1. 修改 env 存儲(chǔ)到 emmc 2. 設(shè)置 BOOT_DELAY 為 5,默認(rèn)是0
./build.sh kernel # 比較流暢，就是耗時(shí)
./build.sh buildroot # 這一步特別耗費(fèi)時(shí)間，并且還需要根據(jù)錯(cuò)誤提示進(jìn)行修錯(cuò)處理，我做的一些修改做了一個(gè) patch 文件放在附件中，僅供參考
./build.sh firmware # 將需要燒寫的文件存放到根目錄的 rockdev 目錄，這樣方便燒寫
#./build.sh updateimg # 這一步是打包成一個(gè)單獨(dú)的 img，沒(méi)有成功，所以采用了分區(qū)燒寫
執(zhí)行完 ./build.sh firmware 之后就可以看到 rockdev 目錄下的內(nèi)容
? ll rockdev/
lrwxrwxrwx red red 18 B Wed Aug 9 14:30:44 2023 ? boot.img ? ../kernel/boot.img

.rw-rw-r-- red red 4.3 MB Wed Aug 9 14:30:44 2023 ? userdata.img
可以看到這里很多是軟鏈接，其中一個(gè)比較重要的 recovery.img 是沒(méi)有的，這個(gè)文件沒(méi)有會(huì)導(dǎo)致 uboot 和 kernel 不能正常工作，后來(lái)我從 YY3568-Debian10-xxxx.img中解包出來(lái)了 recovery.img。至此，所有需要的文件都準(zhǔn)備好了。下面就開始準(zhǔn)備分區(qū)燒錄了。
2. 分區(qū)燒錄文件
因?yàn)槲以?Fedora 下沒(méi)有打包出來(lái)一個(gè)完整的 img,所以就需要分區(qū)燒寫（實(shí)際這樣也方便，可以隨時(shí)更新kernel，uboot或者rootfs，一般開發(fā)只用更新這些就可以）。這時(shí)候就出現(xiàn)了一個(gè)新的問(wèn)題分區(qū)的地址該如何填寫呢？通過(guò)查找文檔，看到了一段描述：
測(cè)試確實(shí)可以讀出來(lái)分區(qū)信息，按照分區(qū)信息填寫將文件燒錄進(jìn)去就可以了。
3.引導(dǎo)啟動(dòng)
因?yàn)槟J(rèn)的 bootcmd 會(huì)首先嘗試 boot_android, 所以可以修改 bootcmd 直接啟動(dòng) boot_fit.加快引導(dǎo)。因?yàn)榇虬鰜?lái)的 boot.img 是 FIT 的。
前面部分的關(guān)鍵引導(dǎo)日志如下，完整的我放到附件*附件：yy3568_log.zip中了。
