i changed
<cal_uart>/uart_pm.pl[/b]:L1933:rx_char_ready to rx_not_empty in order to irq <= ... rx_not_empty ... then it worked well. <div align='right'><{post_snapback}> (index.php?act=findpost&pid=13014) --- Quote End --- [/b] --- Quote End --- Hi, I am trying to use cal_uart with uClinux. Tx works fine but linux crashes in Rx .... I tried to do the correction specified above ...but i could not find the file uart_pm.pl. But there is a file em_uart.pl ....is this the same file to do the correcton ? this is line 1933 from uart_pm.pl "(ie_rx_char_ready && rx_char_ready )", do i have to change both ie_rx_char_ready and rx_char_ready ? thanks in advance, Vishal
