Hi all, I created a tool for remote command execution on a host machine from CMM2. I use it to kick off CSUB compilations from my CMM2, so I don't have to switch back and forth between host and CMM2, do manual transfers etc. The tool also allows easy file transfer between host machine and CMM2. See README below for more info. Cheers, Ruben/Epsilon. REXEC: Remotely execute commands on host from CMM2 -------------------------------------------------- Author: Epsilon Changelog --------- 0.1: Initial version Description ----------- REXEC allows you to remotely execute commands on an attached host machine from the CMM2 command line. For example: > *rexec shell dir /w REXEC07101972 shell_cmd_to_pc dir /w REXEC07101972 shell_ret_from_pc 0 REXEC07101972_DONE REXEC07101972 shell_out_from_pc Volume in drive C is OS Volume Serial Number is 8497-A711 Directory of c:\cmm2\rexec\host [.] [..] arm-gcc-link.ld armcfgenV143join.bas armcfgenV143merge.bas ARMCFunctions.h Make.bat rexec.py 6 File(s) 54,007 bytes 2 Dir(s) 79,417,647,104 bytes free REXEC07101972_DONE REXEC07101972 shell_err_from_pc REXEC07101972_DONE Commmunication goes between a rexec.bas client on the CMM2 and a rexec.py server on the host, connected via serial. Following commands are supported on the CMM2 side: rexec upload <local file path> [remote file path] rexec download <remote file path> [local file path] rexec shell <remote shell command> rexec quit: Request REXEC server to quit. Upload and download use the xmodem protocol but correct for filesize, so you don't end up with those pesky trailing bytes at the end of a transfered file. The server on the host is started as follows: python rexec.py -p <serial port> -b <baudrate> Example: python rexec.py -p COM8 -b 115200 rexec.inc and csubgen: --------------------- rexec.bas just forwards the command line string to rexec.inc, so you can easily build rexec based scripts by #including rexec.inc. An example of such a script is csubgen.bas, also included in this package. csubgen remote compiles a given C file and optional headers and transfers the resulting CSUB back to CMM2. Example: *csubgen merge parseGetNextCSUB.c REXEC07101972 xmodem_send_to_pc parseGetNextCSUB.c 5286 Done. REXEC07101972 shell_cmd_to_pc make parseGetNextCSUB merge REXEC07101972 shell_ret_from_pc 0 REXEC07101972_DONE REXEC07101972 shell_out_from_pc REXEC07101972_DONE REXEC07101972 shell_err_from_pc REXEC07101972_DONE Done. Remote compile OK. REXEC07101972 xmodem_receive_from_pc parseGetNextCSUB.bas 1724 Done. So you can now kick off CSUB compilations from the comfort of your CMM2 :-) Required CMM2 firmware version ------------------------------ V5.06.00 Required Python version ----------------------- 3.x csubgen assumes a Windows host with the GNU ARM embedded toolchain end DOS MMBasic are installed and in the path. ToDos ----- Accept wildcards in rexec upload/download filespec. Limitations ----------- * rexec is only tested against a Windows host but should also work with MacOSX or Linux. ( Output is too verbose. GitHub ------ https://github.com/epsilon537/rexec_cmm2 rexec.zip Epsilon CMM2 projects |

That really is neat. One of these days I will spend the extra effort that will allow me to move on from popping the SD card in and out ;-) Tom MMBasic for Linux, Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |
