器件型号：cc3300 工具与软件：
各位专家、您好！
我要将我们的版本移植到使用新的 SDK 1.0.0.3版本、并注意到了一个问题。
设置：
CPU - AM6231定制电路板
WLAN - CC3300
AM62X PSDK - 09.02.01.10
CC33XX SDK - 1.0.0.3
在将更新的源代码/补丁/二进制文件添加到 Yocto 构建后、我注意到更新后的内核模块会拒绝新的 cc33xx-conf.bin 文件。

上面的示例显示内核模块需要一个较小的 conf 文件。 我注意到、此 SDK 版本中有更多配置。 在四处寻思后、我发现 cc33xx_kernel.patch 创建的 conf.h 文件是错误的版本。
$ cd path/to/cc33xx/sdk/1.0.0.3 $ grep -r CC33XX_CONF_VERSION . ./cc33conf_src/conf.h:#define CC33XX_CONF_VERSION 0x01070070 ./cc33conf_src/cc33conf.h:#define DEFAULT_VERSION_SYMBOL "CC33XX_CONF_VERSION" ./patches/cc33xx_kernel.patch:+#define CC33XX_CONF_VERSION 0x01070050 ./patches/cc33xx_kernel.patch:+ header.version = cpu_to_le32(CC33XX_CONF_VERSION); $ hexdump -s 4 -n 4 -C cc33xx_rootfs/lib/firmware/ti-connectivity/cc33xx-conf.bin 00000004 70 00 07 01 |p...| 00000008
上面的示例显示提示补丁创建了错误的 conf.h 文件并确认 SDK 中分发的 cc33xx-conf.bin 文件中使用的 CC33XX_CONF_VERSION。
与 该补丁创建的 conf.h 和 cc33conf_src 中分布的 conf.h (忽略变量的类型差异)不同时、情况会变得更加明显。
为了修复这个问题、我将 cc33conf_src/conf.h 文件丢弃到我的内核源代码树中并重新构建。 一切都很好。
我在故障排除过程中还遇到了使用 cc33xxconf 时遇到的问题、但我将为此创建另一个线程。
