Compiler/PROCESSOR-SDK-AM437X: TCP socket max number of connections

Hi Bin,

Did you change the _ipcfg.SockMaxConnect from 8 to 16?

According to ndk_3_61_01_01\docs\ndk\NDK_API_Reference.html

_ipcfg.SockMaxConnect – Maximum Connections on a Listening Socket

Default Value 8

Description This is the maximum number of connections a socket will pend waiting for a sockets NDK_accept() call from the application. Note: This value is also the upper bounds of the maximum connection argument supplied by an application via the sockets listen() function (calls with higher values are silently rounded down).

Hi Ming,

Yes, I tried this API :

    temp = 16;
    CfgAddEntry(hCfg, CFGTAG_IP, CFGITEM_IP_SOCKMAXCONNECT,  CFG_ADDMODE_UNIQUE, sizeof(uint32_t), (uint8_t *)&temp, 0);

but It's still the same.

Hi Bin,

#define DEF_SOCK_MAXCONNECT 8

in L:\ti_am4_610\ndk_3_61_01_01\packages\ti\ndk\inc\stack\inc\resif.h.

You may need to rebuild the NDK after the changes.

Ming

Hi Ming,

How to rebuild the NDK?

I can not find the information.

Hi Bin,

On Windows Processor SDK RTOS installation, Assuming you installed the processor SDK RTOS under C:\ti

set XDC_INSTALL_DIR=C:/ti/xdctools_3_55_02_22_core
set gnu.targets.arm.A9F=c:/ti/gcc-arm-none-eabi-7-2018-q2-update
path=%path%;C:/ti/xdctools_3_55_02_22_core
set SYSBIOS_INSTALL_DIR=c:/ti/bios_6_76_02_02

gmake -f ndk.mak clean

gmake -f ndk.mak all

Ming

Hi Ming:

I built a .BAT file , and copy the commands:

set XDC_INSTALL_DIR=C:/ti/xdctools_3_55_02_22_core
set gnu.targets.arm.A9F=c:/ti/gcc-arm-none-eabi-7-2018-q2-update
path=%path%;C:/ti/xdctools_3_55_02_22_core
set SYSBIOS_INSTALL_DIR=c:/ti/bios_6_76_02_02

gmake -f ndk.mak clean

gmake -f ndk.mak all

into this file, and copy the file to C:\ti\ndk_3_61_01_01, then run it, get a error as follow:

gmake: *** [ndk.mak:125: all] Error 2

Hi Bin,

Change the following variables in ndk.mak file directly, then do "gmake -f ndk.mak clean" and "gmake -f ndk.mak all":

XDC_INSTALL_DIR=C:/ti/xdctools_3_55_02_22_core (line 17)

SYSBIOS_INSTALL_DIR=c:/ti/bios_6_76_02_02 (line 18)

gnu.targets.arm.A9F=c:/ti/gcc-arm-none-eabi-7-2018-q2-update (line 46)

Ming

Hi Bin,

Try the following in Windows:

gmake -f ndk.mak XDC_INSTALL_DIR=C:/ti/xdctools_3_55_02_22_core SYSBIOS_INSTALL_DIR=C:/ti/bios_6_76_02_02 gnu.targets.arm.A9F=C:/ti/gcc-arm-none-eabi-7-2018-q2-update

Ming

Hi Ming,

I tried to fix the ndk.mak file as follow:

XDC_INSTALL_DIR ?= C:/ti/xdctools_3_55_02_22_core  (17）
SYSBIOS_INSTALL_DIR ?= C:/ti/sysbios_6_76_02_02      (18)
NS_INSTALL_DIR ?= C:/ti/ns_2_60_01_06                     (19)
gnu.targets.arm.A9F ?= C:\ti\gcc-arm-none-eabi-7-2018-q2-update (46)

It's OK. the ? can not be  omitted.

But the max number of connections is still 8.

Hi Bin,

Have you change the

#define DEF_SOCK_MAXCONNECT 8 --> 16

in L:\ti_am4_610\ndk_3_61_01_01\packages\ti\ndk\inc\stack\inc\resif.h.

AND re-built the NDK?

Ming

Hi Ming,

I had changed it before re-building.

It didn't work.

Hi Ming,

I find that the reason why the link cannot be added is that the function accept() in the server returns an error:Memory allocation erro.

Are there any other settings that need to be changed?
