I have configured the UART in SOPC Builder with RTS/CTS,
but I don't want to use it in software.
If I have no cable attached (CTS high), program hangs.
How can I clear the device flag "ALT_AVALON_UART_FC" by software ???
static void alt_avalon_uart_txirq (alt_avalon_uart_dev* dev,
alt_u32 status)
{
/* Transfer data if there is some ready to be transfered */
if (dev->tx_start != dev->tx_end)
{
/*
* If the device is using flow control (i.e. RTS/CTS), then the
* transmitter is required to throttle if CTS is high.
*/
// !!!TF
// if (!(dev->flags & ALT_AVALON_UART_FC) ||
// (status & ALTERA_AVALON_UART_STATUS_CTS_MSK))
if(1)
thanks
