Hi,
My customer use TMP102.c to driver TMP112.
When probe device and read 0x01, it will show bus error msg:
”BUS ERROR:noisy bus/unexpected start/stop tag: msgs(n:2 cur:0 tx) bc(rx:1 tx:1) mode:FIFO slv_addr:0x48 MSTR_STS:0x001121c4 OPER:0x00000010”
Below is driver code, could you please help to check?
Thanks
