總結一下, 遇到的問題有:
- dts 修改後未更新 resource.img (dtb包在resource.img)
- toolchain 請務必使用 arm-eabi-4.6, 驗證過使用 4.8, 遇到有編譯上與編譯完成後進不了系統的問題
- 文件有部分的 typo: chapter-05-general-register-file(grf).pdf
GRF_SOC_CON1[5] 基本上0,1值的描述與GRF_SOC_CON1[6]是一樣的
但是文件 chapter-28-i2s-2-channel.pdf 在 28.5 Interface description 中的描述
I2S has 2 IOMUX, which controlled by GRF_SOC_CON1[5].
假設 chapter-28-i2s-2-channel.pdf 為真, 兩組外部接腳只能選用一組音效輸出
目前個人的實做上, 兩組接腳只有成功 GRF_GPIO0B_IOMUX 一組
在嘗試 GRF_GPIO1A_IOMUX 一組, 驗證是不成功的, 失敗原因: 不明
就目前工作需求, 現階段已滿足後續測試需求, 如果其他先進驗證成功的也請回文告知, 感恩
- 有想嘗試編成模組(.ko), 但是功力不到位, 載入後系統提示:
rockchip-ssm2603 audio-ssm2603a.21: ASoC: CODEC (null) not registered
估計是因為在載入時, 源碼沒有去 dtb 撈出 iic addr. 的資訊, 所以驅動沒掛上,
如果其他先進知道如何處理, 也請回文告知, 感恩
# 4. 後來嘗試成功了, 想了下 codec 的code 應該可以先 built-in, 所以 make menuconfig
SoC I2S Audio support for rockchip - SSM2602/SSM2603/SSM2604
…
<*> Build all ASoC CODEC drivers
…
編譯失敗:
sound/built-in.o: In function rk610_codec_probe': last.c:(.text+0x8c274): undefined reference to rk610_control_init_codec’
sound/built-in.o: In function rk616_set_dai_sysclk': last.c:(.text+0x8d034): undefined reference to rk616_mclk_set_rate’
make: *** [vmlinux] Error 1
直接去掉編譯失敗的 codec

以下有省略一些 printk(…) 的輸出, 所以行號對不上, 但是看前後內容也可以知道關鍵點在哪
rk_ssm2602.c 基本上是拷貝 sound/soc/rockchip/rk_rk312x.c 做修改, 這裡就不浪費各位先進的眼力了
