Hi, a new batch of jetson tx2 has arrived and there is an error. What could be the problem?

    pio timed out addr: 0x5a tlen:28 rlen:4
    --- register dump for debugging ----
    I2C_CNFG - 0x22c00
    I2C_PACKET_TRANSFER_STATUS - 0x10001
    I2C_FIFO_CONTROL - 0xe0
    I2C_FIFO_STATUS - 0x800040
    I2C_INT_MASK - 0x7d
    I2C_INT_STATUS - 0x0
    i2c transfer timed out addr: 0x5a

Not working on the - left. Working - right.
Identical stickers.

Were they both flashed with the same software release? Are these using the dev kit carrier board, or a different carrier board? If this is not the dev kit carrier board, then did you use the device tree and firmware provided by the manufacturer of the carrier board?

FYI, different carrier boards require different device trees. Device trees are related to how traces are routed. i2c is something which might fail if the device tree is incorrect, and the default flash software is only for the dev kit carrier board.

Thanks for the answer. The problem has been resolved. The sensor was faulty.
