器件型号：TAS2560

你(们)好。

我正在使用连接到定制板的 TAS2560EVM。 电源、IRQ 和 i2c 通信似乎正常。 我正在使用此处提供的驱动程序 ：https://git.ti.com/cgit/tas256xsw-android/tas2560-android-driver/ 、但在尝试使用 tinyplay 时出现以下错误： 

tinyplay sdcard/Download/piano2.wav -D 5

我尚未使用您的 PPC3工具创建任何音频 cfg、因为该驱动程序似乎未读取任何配置文件。 这是正确的方法吗？

该错误是否与缺少的配置文件有关？

我应该改用此驱动程序吗？： https://git.ti.com/cgit/tas2557sw-android/tas2559-android-driver/

    您好 Justin、您对此主题是否有任何反馈？

    目前、我们的电路板未将特定复位 GPIO 连接到 TAS2560EVM (直接连接到 POR)、这是否会影响驱动器的功能？

    大家好、Ivonne、  

    我仍在与我们的固件团队合作研究此问题。 我不会期望重置会成为问题、但在我们处理此问题时、我一定会记住这一点。

    在使用 tinyplay 之前、I2S clk 应已就绪。 TAS2560使用外部 DSP 来运行 spk 保护、因此如果没有 ppc3工具、它可以在 ROM 模式或旁路模式下运行。

    RESET 引脚应始终处于未激活模式。 否则、芯片将无法工作。

    您好、shenghao、复位是引脚处于非激活模式。 我还做了一些返工、现在我将 RESET 引脚连接到 GPIO、并由驱动器正确驱动、但仍会发生严重错误。

    丁 感谢您的指示、我确保 I2S 时钟始终处于启用状态、irq_work_routine, Critical ERROR B[0]_P[0]_R[42]= 0x0但日志已更改、我再也看不到：

    tas2560_dev_write, ERROR, L=123, E=-6

    现在日志更大(歌曲始终尝试重现)

    我最终得到：

    tinyplay sdcard/Download/piano2.wav -D 5                          
    Playing sample: 2 ch, 48000 hz, 16 bit
    Error playing sample

    我注意到、虽然我正在播放6秒的音频、但超时时间在12秒后发生。

    此外、我只有1个 tas2560 IC、我正在使用 Android 单声道驱动程序、但当我尝试重现单声道音频时、我会遇到以下错误：

    Sample is 1 channels, device only supports >= 2 channels

    现在、我已经使用48kHz 速率进行了测试、I2S 时钟设置为1536000Hz。

    附加的是新日志

    你(们)好，Ivonne

    尽管存在单声道应用、但请使用立体声音频文件来播放。 在播放期间、请转储寄存器

    命令 

    i2cset -y -f 0 4c 0 0
i2cset -y -f 0 4c 7f 0
i2cset -y -f 0 4c 0 0
i2cdump -y -f 0 4c
    PS： 
    0是 i2c 总线编号 
    4c is 7-bit i2c device address

    为什么寄存器2为0x01而不是0x00、这意味着芯片处于断电状态。 您确定芯片已通电吗？

    我手动将寄存器设置为0、并尝试播放音频。 日志显示了相同的情况、最后我转储寄存器、它返回到1。

    我意识到任何 i2c 配置都适用、但如果我使用 i2set 手动写入、就会适用。
    我将调试设置寄存器的驱动程序部分、并使用可能发现 的任何结果进行更新。

    你(们)好。

    我仔细检查我的 i2c 通信、一切都好。

    此外、Vbatt 连接到5V、IOVdd (J30)连接到3.3V。

    我尝试使用和不使用升压功能为器件加电、并重新生成不支持电池保护、欠压和 H 类的模式2 96k 但仍然不幸运。

    我将按照建议彻底检查 I2S 信号。

    很抱歉、由于其他一些优先事项、我们的回复延迟了。 我们无法使 i2c 时钟信号正常工作、这可能是由于某些硬件返工。 不过、我们已经讨论过、客户希望继续使用 TI 系列中的另一个 IC。

    感谢你的所有帮助。 我认为您可以将此主题标记为已关闭、因为我们将不再使用此特定 IC。
