TDA4VEN-Q1: MCSPI1 IOSET

Part Number: TDA4VEN-Q1
Other Parts Discussed in Thread: SYSCONFIG, TDA4VH

Hi Ti experts,

Currently, I'm using a custom-built hardware to test SPI, with spi0 and spi1 provided for testing.

Spi0 works fine, but spi1 fails to communicate.

I've tried configuring the spi1 pins according to the instructions in SysConfig, but it still doesn't work.

Do I need to consider IOSET when configuring the MCSPI pins on the TDA4VEN?

If so, how do I know which combinations are acceptable?

Is there any reference files?

Is the following configuration acceptable?

Thanks a lot!!

Hi Alice,

The IO sets for the device will normally be visible on the SysConfig tool in the bottom right, but I see it is not properly displaying. I will investigate this issue.

Here are the IO set groups for SPI1. Your selection for SPI1 pins conforms to IO Set 1.

Signal Name	IO Set 1	IO Set 2
SPI1_CS3		B24
SPI1_CS2		H20
SPI1_CS1	K22	A24
SPI1_CS0	L21	H24
SPI1_CLK	M26	H22
SPI1_D0	N27	H25
SPI1_D1	M27	J23

Which software environment are you using? Can you please confirm the device tree is properly populating the pinmux and configuring McSPI if using Linux?

Regards,
Mark

Hi Mark,

I am using RTOS within the vision_apps (mcu2_0) environment.

I have only modified the example.syscfg file, and the ti_pinmux_config.c is being generated automatically, which appears to be configured correctly.

However, as you noted, my SysConfig interface does not display the IO Sets information (as shown in the screenshot).

If it were to be displayed, what would it look like?
