we tested the cal_uart's irq signal is only active for 1 clock period so

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.

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
