UPP driver OMAP6478 Transmission

Hi,

I have downloaded UPP_BIOS_Driver_Install_v10.zip from Wiki

I need to configure this driver for A transmit mode and B Recieve mode(Duplex1)

I have done the following changes in UPP_Config()

// start with default settings
*upp_setup = UPP_USERPARAMS;

// apply common settings
upp_setup->params.A.clock_div = upp_clock_div;
upp_setup->params.A.fxn_eow = (upp_CbFxn)Upp_Complete_CB;
upp_setup->params.A.fxn_dpe = (upp_CbFxn)Upp_Error_CB;
upp_setup->params.A.fxn_err = (upp_CbFxn)Upp_Error_CB;
upp_setup->params.A.fxn_uor = (upp_CbFxn)Upp_Error_CB;
upp_setup->params.A.idle_value = 0xAAAA;

//
upp_setup->params.B.clock_div = upp_clock_div;
upp_setup->params.B.fxn_eow = (upp_CbFxn)LOCAL_upp_complete_cb;
upp_setup->params.B.fxn_eol = (upp_CbFxn)LOCAL_upp_complete_EOL;
upp_setup->params.B.en_enable = TRUE;
upp_setup->params.B.en_wait = TRUE;
upp_setup->params.B.en_start = FALSE;
upp_setup->params.B.inv_clock =TRUE;
upp_setup->params.A.width = 16;
upp_setup->params.B.width = 16;
upp_setup->params.A.direction = upp_dir_xmit;
upp_setup->params.B.direction = upp_dir_rcv;
upp_setup->params.channels = 2;

 

I am able to recieve data bytes with this configuration.

It would be of help if you could help me configure UPP driver in Transmit mode

 

Thanks and regards

Veena

    Veena,

    This configuration looks correct for duplex mode 1.  The important thing is to set the "direction" fields appropriately for both channels, and to set the peripheral in 2-channel mode.  It looks like you've done that, so this configuration should work.  Do you run in to some problem at run time?  If so, please describe what happens.
