TMS320C6748: Receive data sent by FPGA through SPI

I want to store data in SPI_ In FLASH

可以参考starterware里的spiflash例程。C:\ti\C6748_StarterWare_1_20_04_01\examples\evmC6748\spi。starterware可以到下面网站下载。

Yes, I learned this routine before. But now I want to use C6748 as a slave to receive data, and this program uses it as the host. Perhaps if it is not used as a routine for the slave, can you provide me with specific ideas for slave programming? Regarding the main programming modules of the program and the settings I need for each register on the board. I really need your help.

I have studied the routine you provided and written SPI in this program_ The data of FLASH is generated by myself. When I want to work in SLAVE mode, which parts should I set? At present, I have made the following modifications to the program: 1. Set SPI mode to SLAVE mode. 2. Delete the relevant settings for CLK. I need your help to understand which modules I should set up and how to proceed.

对应的寄存器位的配置按照下面TRM上的表格。
