1.These lines are sensed only during boot up of the AWR device.Is it TM4CI29 chip programming detection or AWR1843 chip programming detection of pin state?Or is it triggered by a change in the state of the hardware connection?

2.Is there a source code detection pin reference program?

Can I replace the TM4C129 chip with the TI XDS110 Debug Probe?If I can replace it.Can you give me a plan?thank you

Hello,
The SOP pins are of the AWR1843 device. When the AWr1843 device bootup it senses the state of these pins to decide the bootup mode.
These need to be driven to the desired state (weak drive) external to the AWR1843 before the device is released out of reset.
This detection is done in the hardware, there is no software involved in this.

Regards,
Vivek

Thanks for your answer, there is no software design, but I see the connection on the schematic diagram is the pin connecting to AWR1843 chip, is there a conflict?

Hello,

Am not sure I understood the query, what is the conflict you are referring to ?
