MMWCAS-DSP-EVM: The board fails to boot up.

Part Number: MMWCAS-DSP-EVM
Other Parts Discussed in Thread: DRA742, PCF8575, PMP

Hello, 

I would like to resolve the error when trying to boot MMWCAS-DSP-EVM.

I have connected all the hardware correctly and followed the instructions in mmwave_studio_cascade_user_guide.pdf.
When I start Teraterm, I get the following error message and can't proceed.

I checked the hardware connections and replaced the SD card, but the problem persisted.

I'm finding threads with all the same situation as me(e2e.ti.com/.../mmwcas-dsp-evm-the-board-fails-to-boot-up).
