Part Number: AM625

Tool/software:

Hi TI Experts,

Customer build their AM62x development board, and using SDK10.0, for a new IOT Gateway project (upgrade from the old AM335 platform).

They use the same DDR size 2GB the same as we used in EVM. Their schematic was also reviewed by our HW expert.

And they are using the prebuilt base image, it is working normally on the EVM.

However, when customer use SD card boot using the prebuilt base image on their development board, they will meet the below problem, and stuck in the uboot stage.

    Hi Linjun,

    Customer does not reserve jtag on their board so cannot connect to ccs.

    After looking into the source code, the timeout is generated from OMAP I2C.

    Could you let us know which peripheral it is reading so that customer could analyze it?

    Many Thanks,

    Kevin

    Hi Kevin,

       Could you please ask customer  remove the configure "CONFIG_TI_I2C_BOARD_DETECT" to check. As to there is E2PROM on  EVM board for configuration. Thanks.
