+^ Affects   | RS485 via UARTx on MBa57xx Revsion 01xx  |
-^ Issue     | During i.MX7 reset the UARTx.CTS# pin is low by default (CPU internal pull down)  |
+^ Issue     | During AM57xx reset the UARTx.CTS# pin is low by default (CPU internal pull down)  |
-^ Effect    | Using the MBa7x RS485 circuitry in a half-duplex slave device or half-duplex multi-master environment may block the RS485 bus during i.MX7 reset.\\ The bus is released as soon as the UARTx.CTS# pin is properly configured by software (e.g. U-Boot, Linux, etc.)  |

+^ Solution / Workaround  | Add a 10k pull up to the UARTx.CTS# signal on carrier board \\  This behaviour will be fixed with MBa57xx REV.02xx   |
