器件型号：AM4378

大家好、

我正在使用 TI SDK Linux 07.03.00.005开发 ARM MPU AM4378通用 EVM。我想通过 MMC2接口将 WLAN 芯片连接到 MPU。在多次尝试失败后、我决定执行一些测试、以确保 MMC2接口正常工作。我只需将 SD 卡连接到 EVM 板即可检查卡检测过程。不幸的是、几天后、我仍然没有取得进展。

首先、我使用 EVM 上的摄像头1接头来连接 SD 卡、因此我在*。dts 文件中重新配置了引脚多路复用器。

MMC2外设的 pinmux 在此处进行配置(我检查了 AM437x 数据表以获取每个引脚的 padconf 偏移的多路复用模式和参考手册)：

我检查了 SD 卡和 EVM 接头之间的连接数次-仍然正常。此外、在示波器上探测引脚 mmc2_clk 和 mmc2_dat 后、我可以看到频率为400kHz 的时钟信号和 dat 引脚上的状态变化。但是、探测 SD 卡的所有尝试均失败。

我检查了许多 SD 卡、在 MMC0接口上、始终可以正确检测到它-我从未在迹线上看到 CMD1。连接到 MMC2的 SD 卡相同-提供错误、并且可以在迹线上看到 CMD1。

我不知道如何解决这个问题。有人可以帮助我解决这些错误吗？

您好 Szymon、

对延迟答复表示歉意。您是否仍需要帮助？

请注意、TI 可以支持调试 TI 的软件和硬件、但我们不能支持调试其他公司的软件和硬件。在我们的 TI Linux SDK 中、我在文档/或驱动程序/中的任何位置都看不到"slabs、wf200"。您需要联系 Silicon Labs、以帮助他们的外设在 Linux 系统中运行。如果您发现 TI 方面的问题(例如、较低级别的 TI 驱动程序导致了问题)、我们可以在这方面提供帮助。

此致、

Nick

您好、Nick、

感谢您的回答。目前我不需要帮助。我解决了这个 WiFi 芯片的问题(是的，它是 SiliconLabs 芯片)。

由于芯片无法正常工作、我决定尝试将 SD 卡连接到 MMC2接口-甚至该 SD 卡也无法正常工作-但现在我假设物理有线连接中存在另一个故障 (使用了低质量 MicroSD -> SD 适配器，可能某些针脚未连接)。

芯片不工作的原因是 CMD0时钟问题- MMC 控制器在发出 CMD0后停止时钟信号-从协议规范的角度来看、这是可以的、因为 CMD0不需要响应。 Hov串这个特定的芯片初始化过程要求在发出 CMD0后驱动时钟信号、以使芯片响应。如果在 CMD0之后时钟停止、则发出其他初始化命令、如 CMD5、CMD8会产生超时错误。这是特定于此第三方芯片的、因此我修改了位 MMC 驱动程序内核、因为 SiliconLabs 建议通知 MMC 控制器 CMD0之后的响应是预期的。在这些修改之后、最终正确探测芯片并由驱动器进行配置。

当我写上述帖子时，我不清楚这一点，因为在内核跟踪转储中，我没有注意到芯片在 CMD0之后没有响应，所以我提前提出了 SiliconLabs 的建议-这是我的错:)当我的所有想法都失败了，我假定也许可以在示波器上检查总线-特别是对于 CMD0 -可能会让我有任何方法来解决这个问题-然后我还记得 SiliconLabs 说过时钟。

再次感谢您、致以诚挚的问候。
