I2C-GP4 can't access addr 0x68 & 0x69

I want used Jetson Xavier I2C-GP4. I found that the bus can’t access addr 0x68 & 0x69, but can access addr 0x18 & 0x19. This bus can only support 64 addrs?

From the TRM it can support 7bit or 10bit slave address.
What kind of message for the failed case?

I’m used bosch BMI088, it have two i2c addr. When used I2C-GP4 ,only can find addr 0x19. But used I2C-GP2, can find 0x19 & 0x68. I don’t know where I can find more messages.

What’s the kernel message while access the 0x68/0x69 slave address.

From the log show the driver support the address range.
Could you probe the signal to have a check if the device have ack for the scan command.

Using logic analyer, it show “Setup Read to [0x33] + ACK”. I belive 0x33(110011b) is addr 0x19(11001) with the least bit 1. For the other addr, it only show NAK.
