[参考译文] AM3352：内核 6.1.97 的 SDK 兼容性

在最新的 SDK 中、我们使用了processor-sdk-09.01.00-config.txt

在此 SDK 上下文中、我们正式支持的唯一内核是与该 SDK 的 Yocto 配置相关联的内核、即 processor-sdk-09.03.05.02-legacy-config.txt 、请参阅 https://software-dl.ti.com/processor-sdk-linux/esd/AM335X/09_03_05_02/exports/docs/linux/Release_Specific_Yocto_ layer_Configuration.html#Yocto-layer-configuration。 这是我们发布的经过测试和认证的配置。 任何其他配置都可能导致我们无法轻易支持的问题。

在最新的 SDK 中、我们使用了processor-sdk-09.01.00-config.txt配置文件、其中包括内核版本 6.1.119。 我们目前正在移植 Infineon (v6.1.97) 针对内核 6.1.119 发布的 Wi-Fi/BLE 驱动程序、但我们面临一些挑战。

这些版本似乎足够接近、您面临什么问题？ 看来应该能够解决这些问题。

此致、Andreas

尊敬的 Andreas：

我们交叉编译了内核 6.1.119 的 Wi-Fi 驱动程序、每当我尝试加载驱动程序时、都会持续收到以下错误：

我本周在 PTO 上、但下周我将再次获得 E2E 支持。 谢谢。

尊敬的 Andreas：

是否有任何更新？

此致、
Pratik P.

尊敬的 Pratik：

这是一个第三方驱动程序、因此我们在这里可以支持的内容方面受到限制。 我在您的日志中看到有关固件加载和 DMA 的错误、这些错误可能对模块的运行至关重要、也可能不重要。 您应与供应商核实这些错误消息是否具有任何重要性、并将它们提供给您的日志以供查看。

我在线搜索速度非常快、找到了这篇 E2E 帖子、您可能需要尝试一下： https://e2e.ti.com/support/processors-group/processors/f/processors-forum/541016/am335x-error-message-in-sdio-driver/1972129#1972129

另一方面、为了进行测试、我还会尝试最新的上游内核。 AM335x 通常受到很好的支持、因此您应该能够仅构建内核/模块（包括您的 WiFi 驱动程序）/dtb 并将其放入您的系统中进行测试、看看这是否有任何区别。

此致、Andreas
