The user is attempting to port Blimp's OSD onto an ARM board and is facing issues with SPI functionality. The final answer confirms that both I2C and SPI interfaces are required for OSD, and suggests implementing the SpiTransfer function in the ADIAPI_OsdConInit function. The user is advised to check hardware connections and use VDSP for debugging on the evaluation board. The discussion also clarifies that the user should ensure the correct configuration of internal or external flash memory options.

I want to port blimp's osd onto the arm board, do you have specific instructions
osd is initialized by ADIAPI_OsdConInit, The switch is then controlled by ADIAPI_OsdKeyPress. I blocked the Spi related function in ADIAPI_OsdConInit, and the blimp control I defined is still displayed (in advantiv-eval-adv7625-smz-video-evaluation-board). So, if I'm going to implement osd display, where is my spi function going to be implemented?Not in the ADIAPI_OsdConInit function?
Now that my image is out, I can use the iic control to have it display some blocks.If I want to implement spi, I need to implement SpiTransfer in the ADIAPI_OsdConInit function, right?
