Original question:
TDA4VM: 如何启用UART2做串口回环测试
TDA4VM J721E不支持SPI吗？
但是设备树和原理图以及40pin中均有SPI
有SPI驱动，只是开发板上的McSPI口没有和外设连接。开发板上有接OSPI器件。内核里是支持SPI驱动的。https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-jacinto7/08_06_01_02/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/SPI.html
感谢，在您给出的参考文档中，Enabling McSPI Driver时，SPI support并没有McSPI driver for OMAP选项，请问该怎么解决？以及我们企图使用40 pin中的SPI 5引脚，请问该如何配置？
请参考下面的帖子，FAQ里有具体的步骤。https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1068491/tda4vm-how-to-enable-mcspi-device-tree-in-tda4
