Hi guys,
I have a problem about communicate uart2(rs232) in baseboard.
I have checked dtsi file, i think it is okay, but when I have checked "fsl-lpuart"
cat fsl-lpuart
: uart 0(debug port) works but the others not working
: 2: uart:FSL_LPUART mmio:0x5A080010 irq:62 tx:0 rx:0
: 3: uart:FSL_LPUART mmio:0x5A090010 irq:62 tx:0 rx:0
I think I have connected rx/tx/ground pin appropriately.
Where should i check some point? or something to set more?
I just checked uart2 connection but it doesn't work.
