Dear Sir,
We're testing the uart's operation with the i.mx6 dual lite board.
The Kernel version is "Linux freescale 3.0.35-2666-gbdde708 #6 SMP PREEMPT Mon Feb 16 09:25:50 KST 2015 armv7l GNU/Linux".
And we're using the gnome release package S/W in the i.mx6 dual lite board.
We had found uart unit test app in the gnome release package S/W.
But we think that the app doesn't work well.
Our test result is as follows.
root@freescale /unit_tests$ ./mxc_uart_xmit_test.out /dev/ttymxc2
UART 115200, 8bit, 1stop, PARENB, HW flow disabled
test begin, press 'c' to exit
sent 10000 bytes with speed 102301.790281bps

c
sent 10000 bytes with speed 102432.778489bps
tcount=60000
rcount=0
test exit
root@freescale /unit_tests$
We expect that the rx data will be saved in the uart_read.txt file.
But rcount is 0 and the uart_read.txt file is null.
If there is an additional setting for this test, please let us know.
Sincerely,
