尊敬的 TI 支持团队：
由于我们需要以最大切换速度（以 MHz 为单位）切换 PRU 引脚、因此我获取了 R5F - FreeRTOS 内核和 PRU 内核的参考固件。 对于 R5F FreeRTOS 工程、我使用了参考固件：- empty_PRU_IO_am243x-lp_r5fss0-0_freertos_ti-arm-clang PRU 内核、并将其加载到

}MWare；同样、对于切换 PRU 引脚、我已经采取了措施 empty_am243x-LP_ICSS_g0_pru0_fw_ti-PRU-CGT 并写入了 PRU 引脚切换代码。
遵守上述规定后、我构建了固件并对 AM243x_LP 板进行了编程、从而无法切换 PRU 引脚。
我已经阅读了几个文档并遵循了其中提到的程序。 但是、问题仍然是一样的。
您能介绍一下控制 PRU 引脚的过程吗？
此外、我还会附加我的两个固件。 请进行审核、如果可能、请在最终确认您有 AM243x_LP 电路板、并提供相关措施建议。
