[ECOS] Problem in porting GoAhead Web server on ep7212

["Balaji TS" <balaji_esix at hotmail dot com>]

Dear sir

We are trying to port GoAhead web server on EP7212. We got the GoAHead web 
server from the internet for the eCos. we build it and compiled it for 
EP7212. We ported that and it is not working. After debugging we came to 
know that the required 60 kb of memory could not be allocated by kernel. 
Then we came to know from eCos mail listing that by modifying the Parameters 
in the ecos.ecc file (user value of the CYGNUM_LIBC_MALLOC_MEMPOOL_SIZE to 
1638400), it is possible to allocate the required memory. But it still we 
can't able to port the webserver. the malloc fails to give 60 kb of memory.

please help me in this issue and Suggest a solution.

And the Solution Given by them is to change the user value

cdl_option CYGNUM_LIBC_MALLOC_MEMPOOL_SIZE {
    # Flavor: data
    # No user value, uncomment the following line to provide one.
    user_value 1638400
    # value_source default
    # Default value: 16384
    # Legal values: 32 to 0x7fffffff
};




For More Reference i had send the Reply mail from ecos-discuss as 
attachment.

The most likely problem is that you need to expand the space reserved
for malloc().  In the current version, memory for malloc() comes from
a fixed size pool which is woefully too small for the GoAhead web
server.  Try making this additional configuration change:

cdl_option CYGNUM_LIBC_MALLOC_MEMPOOL_SIZE {
    # Flavor: data
    # No user value, uncomment the following line to provide one.
    user_value 1638400
    # value_source default
    # Default value: 16384
    # Legal values: 32 to 0x7fffffff
};

Note: if you are using the command line 'ecosconfig', you can retrieve
your changes via the "export" command.  For example:

  % ecosconfig export config
  % cat config
  cdl_savefile_version 1;
  cdl_savefile_command cdl_savefile_version {};
  cdl_savefile_command cdl_savefile_command {};
  cdl_savefile_command cdl_configuration { description hardware template 
package };
  cdl_savefile_command cdl_package { value_source user_value wizard_value 
inferred_value };
  cdl_savefile_command cdl_component { value_source user_value wizard_value 
inferred_value };
  cdl_savefile_command cdl_option { value_source user_value wizard_value 
inferred_value };
  cdl_savefile_command cdl_interface { value_source user_value wizard_value 
inferred_value };

  cdl_configuration eCos {
      description "" ;
      hardware    edb7212 ;
      template    net ;
      package -hardware CYGPKG_HAL_ARM current ;
      package -hardware CYGPKG_HAL_ARM_EDB7XXX current ;
      package -hardware CYGPKG_DEVS_ETH_ARM_EDB7XXX current ;
      package -hardware CYGPKG_IO_SERIAL_ARM_EDB7XXX current ;
      package -template CYGPKG_HAL current ;
      package -template CYGPKG_IO current ;
      package -template CYGPKG_IO_SERIAL current ;
      package -template CYGPKG_INFRA current ;
      package -template CYGPKG_KERNEL current ;
      package -template CYGPKG_LIBC current ;
      package -template CYGPKG_LIBM current ;
      package -template CYGPKG_UITRON current ;
      package -template CYGPKG_IO_WATCHDOG current ;
      package -template CYGPKG_IO_WALLCLOCK current ;
      package -template CYGPKG_ERROR current ;
      package -template CYGPKG_NET current ;
      package -template CYGPKG_IO_ETH_DRIVERS current ;
  };

  cdl_option CYGHWR_HAL_ARM_EDB7XXX_VARIANT {
      user_value EP7212
  };

  cdl_option CYGNUM_LIBC_MALLOC_MEMPOOL_SIZE {
      user_value 1638400
  };
