您好、TI 专家。
我们有一个自行设计的 CC3301模块、
我们将 BBB 用于电路板启动。
我们已将 SDIO 频率更改为1MHz。
我们使用 AM335x+BBB 适配器+CC3301 LP、因此可以正常使用。
当我们更换模块时、我们查看了日志、并且在我们设计的模块的末尾还打印了其他错误消息。
[29.524487] wlcore: ERROR boot IRQ timeout [29.531100] wlcore: ERROR ti-connectivity/cc33xx_fw.bin boot signal timeout [29.562133] wlcore: ERROR FW download failed
您能帮助我们解决这个问题吗？
谢谢。
我已经检查了时钟、MISO 和 MOSI 都有信号。
TI 专家。
我们将使用 SDIO 模式来启动电路板。
下面是我的原理图和跳线连接。
然后、我们连接了 IRQ_WL 线路。
以下是我的时序。
我们使用的 cc33xx SDK 是 cc33xx-linux-package-R1.3.2-linux-x64-installer.run
预构建映像为 tisdk-cc33xx-image-1p3p2.tar.xz
AM335x SDK 是 ti-processor-sdk-linux-am335x-evm-08.02.00.24
----------------
我们同时使用了测试环境和图像来比较 TI 的 CC33xx LP。 如果使用 CC33XX LP、则可以正常工作。
您能给我们提供什么建议吗？
谢谢。
您好、TI！
我还使用预构建映像版本进行了测试：版本：1.0.0.1 tisdk-default-image-cc33xx-AM335x-evm.wic.xz (www.ti.com/.../CC33XX-SOFTWARE)。然后、我在我的 TI BP-CC33x1修订版 E2版本上运行它、
但是、当我使用该版本的预构建映像、然后运行 sta_start.sh 时、会显示一条错误消息。

如果我使用新版本的 SDK、是否需要使用较新版本的 cc33xx 芯片？
那么对于本主题、您有什么建议可以帮助我使用我们的模块成功启动吗？
我实际的电路板模块芯片生产日期代码如下所示。
