Hello, Sorry to come with this UART issue again but I had no answer and no better idea but asking people who knows 82xx uart well, people who designed it. My issue about this uart could be approched elseway : why is there a modem_control conditionnal compilation option when PQ2 SCCs (in normal operation mode which is default) take care of CTS,CD signals (Chap 20-8 GSMR_L register DIAG MPC8280 PQ2 Ref. Manual ) ? I fell like that is clearly a design-time choice matter that I need to clarify. And simply : Is this version is known to be broken when activating this option ?
Do not know what this option is, probably for disabling code from another driver. With latest CVS version from denx.de you have only to enable CTS/RTS.. signals in menuconfig. (And read my prior post if you're using SCC4 with SCC_CONSOLE)
