Part Number: TDA2HG
Other Parts Discussed in Thread: DRA742, PCF8575, PMP

Hello，

We use TDA2HG device. The Linux  will boot fail on custom board based on VSDK 03 05. Could you help to have a look?

Thanks

    Hi,

    I see so may errors in the log. (MMC, i2c, SATA)

    Have you ported the u-boot to your custom board?

    Can you be specific where you need help? What step in the u-boot is failing?

    Hi Nikhil,

    We have ported the u-boot to our custom board.  The most boards can boot normal. We don't understand below log:

    Hi,

    What do you mean by 'most boards boot fine'?

    Is this issue only on a specific board? Is this any issue with the specific MMC card being used?

    Regards,

    Nikhil D

    Hi Nikhil,

    Yes,  this issue only on a specific board. We use the same code, include SD boot & EMMC boot.

    Thanks

    Hi,

    If this is happening on a custom board, I doubt it is some issue with the i2c connection.

    The error message is regarding sending i2c messages to configure the GPIO expanders.
