| RS485 bus block in half-duplex mode | |
|---|---|
| Affects | RS485 via UARTx on MBa57xx Revsion 01xx |
| Issue | During AM57xx reset the UARTx.CTS# pin is low by default (CPU internal pull down) |
| Effect | Using the AM57xx RS485 circuitry in a half-duplex slave device or half-duplex multi-master environment may block the RS485 bus during AM57xx 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 |
