AM2732: CSI-2 configration failed.

Hi, 

I will look into this and get back to you later this week. 

Can you attach the AM273x MCU SDK setup code you have already tried to use with this sensor and physical hardware setup being used? Have you already probed the CSI-RX at the AM273x BGA to confirm your cabling setup is giving you good signal integrity for the link?

Thank you,

Hi Randy

I try to upload the syscfg file... I use CSI CLK and DATA 2 lanes.

CSIRX B, 150Mhz , RAW12,
csirx_lane_position_3
csi_clk_p : a6,
csi_clk_n :b6,

csirx_lane_position_1
csi_rx0_0_p : b8
csi_rx0_0_n : a8

csirx_lane_position_2
csi_rx0_1_p : b7
csi_rx0_1_n : a7

The waveform is attached in the file.

Hi Jeong, 

Is this post related to the one here? https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1351211/tmds273gpevm-am273x 

I will look at this again in lab tomorrow. 

Thank you,

Quick update: not a good answer, but we are still trying to find a good way to replicate this problem here. Will update again soon.

In trying to replicate and debug this issue, I have found that we currently cannot support the CSI-2 RX driver found in the AM273x MCU PLUS SDK (https://software-dl.ti.com/mcu-plus-sdk/esd/AM273X/09_02_00_52/exports/docs/api_guide_am273x/DRIVERS_CSIRX_PAGE.html) in a general purpose sensor attach mode. At this time I cannot provide any more information or additional time frame on when this would change.

We have TI AWRx radar front-end CSI-2 RX examples which are part of the MCU Radar SDK (https://www.ti.com/tool/MMWAVE-MCUPLUS-SDK) but these utilize a C6x DSP driver/API and are tightly coupled and documented only in reference to the mmWave Radar Demo framework application. They may be helpful to you to continue work with the AM273x.

However, I would also suggest that you consider porting your application to adjacent TI MPU products such as the AM62x and TDA4x series. These AM62x and TDA4x products have fully tested and fully supported CSI-2 hardware and software references. See:

• https://www.ti.com/tool/SK-AM62
• https://www.ti.com/tool/PROCESSOR-SDK-AM62X

The AM62x Processors SDK, has has multiple documented camera attach examples that may be applicable to your time of flight sensor integration. See: https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/latest/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/Camera/CSI2RX.html
