Other Parts Discussed in Thread: MMWCAS-DSP-EVM, , TDA2, MMWCAS-RF-EVM, AM68, AM69
Hi,
I am using the PROCESSOR-SDK-VISION Version: 03.08.00.00 to build a custom firmware for the MMWCAS-DSP-EVM. The goal is to use the USB3.0 available on the MMWCAS-DSP-EVM as shown in the figure below.
The issue is the USB3.0 port seems not working. I compiled the PROCESSOR-SDK-RADAR, then the PROCESSOR-SDK-VISION, yet the USB3.0 is not enabled on both SDKs. Going more in details, I understand that the USB3.0 port can operate as OTG. I tried in both "gadget" and "host" mode, yet the port seems not functioning. Going through the design files, the port is powered from the TDA2SX processor as shown in the three below figures. The USB1_DRVBUS (AB10) pin on the TDA2 processor should be high to enable the TPS chip and power up the USB stick (gadget) on the USB3.0 port. Yet, when I probed the TDA_USB1_DRVBUS wire using a multi-meter on the board, the signal is low.
I followed this thread which succeeded in connecting an external Hard drive to the TDA2x Demo board. Even after modifying the linux kernel using kernel_menuconfig to load USB related drivers on boot, it still does not work.
I am wondering if the pin is faulty or disabled by design? If it is disabled, can you provide a way to modify the firmware to enable it.
Thank you,
