K60N512VMD100 and MQX RAM allocation (Unable to use full RAM)

Dc5e — Thu, 28 Apr 2011 03:39:12 GMT

Hi,

I'm using the Kinetis K60N512VMD100 with MQX 3.7 and Codewarrior 10.1. I'm trying to use the http server and some sockets at the same time but I noticed that the tasks with the sockets and http server have an error code of PART: Out of Blocks. I'm guessing this means that I've ran out of memory to allocate... right? So I took a look at the lightweight memory summary and it shows that I have 123KB of ram available, but it only uses up 59K. When I look at the addresses, 64K of RAM at 0x20000004 is untouched. Is there any way to be able to utilize the rest of the ram?

Thanks,

Dan

HI,

I guess your problem will be related to socket partition setting try increase RTCS_socket_part_max value:

    /* runtime RTCS configuration */
    _RTCSPCB_init = 4;
    _RTCSPCB_grow = 2;
    _RTCSPCB_max = 6;
    _RTCS_msgpool_init = 4;
    _RTCS_msgpool_grow = 2;
    _RTCS_msgpool_max = 8;
    _RTCS_socket_part_init = 4;
    _RTCS_socket_part_grow = 2;
    _RTCS_socket_part_max = 6; --> increase this value
