[ECOS] printf output problem

[ECOS] printf output problem

[tathagata]

Hi ,
 I am trying to write a serial driver on a new platform of MIPS 
architecture.
diag_printf is working properly.
But printf is not working, system is not hanged but I can not see any 
output.

Here is my configuration

DEVTAB_ENTRY(   test_serial_iol,
                                     "/dev/tty0",
                                     "/dev/ser0",
                                &test_serial_devio,
                test_serial_init,
                test_serial_lookup,     // Serial driver may need 
initializing
                &test_serial_channel
    );

CYGDAT_IO_SERIAL_TTY_CONSOLE = "/dev/tty0"
CYGPKG_IO_SERIAL_TTY_TTY0 = 1
CYGPKG_IO_SERIAL_DEVICES = 1

Thanks in advance.

[ECOS] lwip stack problem with printf

[Tathagata Das]

Hi,
   I am using lwip stack. I have successfully compiled ecos source code 
with lwip_eth template.
But when I am trying to compile my application, I am getting following 
errors:
          1. undefined reference to `printf'
          2. undefined reference to `strcmp'
I have found that there is no LIBC support in lwip_eth template. So I 
have added those packages.
But in that case my system hangs when it is trying to execute printf 
function.

Please tell me how to solve this problem.

Thanks in advance.
