Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

hi expert,

My project using TDA4 VH + SDK 9.1.

When we test our projct HW board, we found that, for pin mux configuration "MMC1_CLKLB" in "J784S4_pinmux_data.c", we cannot find the configure item in sysconfig tool which provide by TI official, but when we try to remove this configuration item, main domain SD card boot mode will be affected.

So, my question is:

1. What is the function of this pin mux configuration item?

2. where can we get configuration information for this pin mux item and in which sysconfig tool module we can configure this pin mux item?

3. what is the affection machnism to my SD card boot mode which produced by MMC1_CLKLB?

thanks

Hi,

I'll check this on my end and get back.

Can you please share which version of the sysconfig are you using?

Hi,

I did check this internally.

This is a loopback clock. It is used to calculate the circuit delay

Since this is not pinned out, I believe that's why it was not part of the syscfg. But I believe ideally it should be there in syscfg, Will take this as a bud within the team.
