TDA4VEN-Q1: Need support for SPI Synchronous transmission

Hi Amarnath,

Could I get clarification for what is meant by "synchronous" transmit? 

If a simple spidev and spi slave configuration is desired for Linux,

• We have this old appnote which is still mostly relevant: https://www.ti.com/lit/an/sprad26/sprad26.pdf?ts=1740755973723&ref_url=https%253A%252F%252Fwww.google.com%252F
• And a devicetree overlay for J7200 that can be referenced for TDA4VEN/J722S: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/arch/arm64/boot/dts/ti/k3-j7200-evm-mcspi-loopback.dtso?h=ti-linux-6.6.y

For RTOS in the MCU+ SDK, 

• We have some documentation here: https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-j722s/10_01_00_04/exports/docs/mcu_plus_sdk_j722s_10_01_00_22/docs/api_guide_j722s/DRIVERS_MCSPI_PAGE.html

Let me know if that answers the question, or if not, please correct my misunderstandings.

Regards,

Takuma
