RTEMS is a single address space, single process OS so you can not exec another
process. You can call the shell command handler from any thread. Make sure you
have enough stack for the thread.
Try something like:
int run_shell_command(const char* cmd)
{
#define CMD_MAX_ARGS (20)
char* cmd_argv = strdup(cmd);
int argc;
char* argv[CMD_MAX_ARGS];
int r;
if (cmd_argv == NULL) {
fprintf(stderr, "shell: command: no memory: %s", cmd);
return 1;
}
if (rtems_shell_make_args(cmd_argv, &argc, argv, CMD_MAX_ARGS) < 0) {
fprintf(stderr, "shell: command: arg parse: %s", cmd);
free(cmd_argv);
return 1;
}
r = rtems_shell_execute_cmd(argv[0], argc, argv);
free(cmd_argv);
return r;
}

hi everyone now i use jffs2 as my flash filesystem. but the time of the scan the device is two long , i find that someone said that when i set the CONFIG_JFFS2_SUMMARY macro ，the time will reduce too much。 but i did not find the realization of the summary. i only find the summary.h and no function realization. if i want to use this to reduce the scan time . how should i do ? i use rtems 4.11.2 and zynq 7000 platform. best wishes ben bin.w...@qkmtech.com ___ users mailing list users@rtems.org http://lists.rtems.org/mailman/listinfo/users

change bsp
hi
1：i want to change the bsp according to the zynq zedboard。it only has console
driver and i2c driver。 so i want to add some drviers i used in bare-metal
software before （such as gpio）。i do not know how to start。
please give me some advice。
i find the function in bootcard.c "rtems_initialize_device_drivers" i
think i need add code here, but the bsp i used installed as lib.so , can i
change the source code?
i do not understand the RTEMS_DRVMGR_STARTUP level 1,2,3,4 ,is there a
example to add my device driver to the rtems architecture？

}

2：another question is how can i enable the interrupt？ in the init task is ok？

Re: Re: the difference between posix user and c user
i google the posix .now i know that posix is the abbreviation of "the Portable Operating System Interface" it is for software compatibility with variants of Unix and other operating systems but you said, "POSIX and the Classic API are both C APIs." than i think the posix is packaged on the basis of the standard C, is it right ? the classic api is the standard c interface , is it right? best wishes bin.w...@qkmtech.com From: Chris Johns Date: 2017-12-29 02:18 To: users Subject: Re: the difference between posix user and c user On 29/12/17 12:00 am, bin.w...@qkmtech.com wrote: > hi everyone: > > i am new to linux and rtems. i do not understand > what the difference between posix user and c user . > > i am confused about these two concept. which condition i should choose posix ? > which condition i should choose c ? > This is a good question and it is understandable why you do not understand the difference. The reason is specific to RTEMS and relates to it's history. The original RTEMS was written in Ada and C and the C API is what we now call the Classic API. It's manual was called the C User Guide hence the name. The Ada version of RTEMS was removed from the source tree and POSIX came a while later. POSIX and the Classic API are both C APIs. The C User manual is now called the RTEMS Classic API Guide.

thanks a lot . i have another question , if i use the smp, can i use the interrupt of rtems? which i want to interrupt period of hard real time of 125us. i do not know the difference of the bare-metal interrupt and the rtems interrupt . is the rtems interrupt have performance loss of the hard real-time? what the schedule method of smp use? is it can affect the interrupt performance? best wishes bin.w...@qkmtech.com From: Chris Johns Date: 2017-12-29 02:08 To: users Subject: Re: smp support On 28/12/17 7:51 pm, bin.w...@qkmtech.com wrote: > *hi: everybody:* > * > * > *i want to use the smp in the rtems.* > * > * > *when i see the c user doc .i find as follows* > * > * > *Warning: *The SMP support in the release of RTEMS is a work in progress. > Before > you start > using this RTEMS version for SMP ask on the RTEMS mailing list. > > is the smp in the developing phase? can it be used in xilinx zynq702? > SMP for the Zynq is supported on the git master.

It might be a good idea if you can. Let me attempt to break down what is happening 1. RTEMS Tools, the GCC compiler, assembler and debugger. You need MSYS2 to build these because of the autoconf configure used and size of the build. I also think cygwin can be used but I do not test this. 2. RTEMS Kernel. I have only built RTEMS on Windows using MSYS2. In theory you any working shell on Windows should be OK but I have not tested this. Again a good working shell is needed because of the autoconf based build system. Items 1 and 2 create native executables and suitable libraries and you can in theory use any Windows environment that runs native Windows executables. > now i get the follow error > > //-- > > Generating Makefile in build directory: > E:/workdir/pallas_SDKworkspace/rtems_kernel_build/build > > sh -c > "/E/workdir/pallas_SDKworkspace/rtems_kernel_build/rtems-4.11.2/configure > --target=arm-rtems4.11 --prefix=/kernelinstall > --enable-rtemsbsp=xilinx_zynq_zc702 --enable-tests --enable-posix > --disable-networking --enable-cxx --enable-rtems-debug" > checking for gmake... no > checking for gmake... no > checking for make... make > checking for RTEMS Version... 4.11.2 > checking build system type... i686-pc-mingw32 > checking host system type... i686-pc-mingw32 > checking target system type... arm-unknown-rtems4.11 > checking for a BSD-compatible install... > /g/software/xilinx/SDK/2017.3/gnuwin/bin/ginstall -c > configure: error: ls -t appears to fail.
