Hi folks, I thought I had a clever way to restore my options after a firmware update: > list "/config.bas" If Mm.Info$(Search Path) = "" Then Print "one" option f11 "chdir " + chr$(34) + "/zmim/src" + chr$(34) + chr$(13) + chr$(10) option f12 "chdir " + chr$(34) + "/mbt/src" + chr$(34) + chr$(13) + chr$(10) option search path "/bin/" ' so this script will run again on reset option autorun on ' this will cause a reset option sd timing fast Else Print "two" ' so this script will not run again option autorun off ' this will cause a reset - note even if autorun was still on it wouldn't ' take effect because running from RAM means that there will be no current ' program after the reset option ram EndIf So the idea is that after updating the firmware you reset the CMM2 and just type *config. I use the AUTORUN trickery because both OPTION SD TIMING and OPTION RAM cause a reset. But it doesn't seem to work, the script doesn't get run a second time. Can anyone explain ? ... it looks like the AUTORUN doesn't occur after a reset due to changing SD TIMING or RAM. Are there different types of reset going on?

Are you sure the search path setting gets maintained after the first reboot so as to cause the else clause to get invoked? You might want to have the code print the current search path right at the start so you'll see what it thinks it is both times... Only thing I can think of... |

Yes, I am sure. And if I then do a hard reset the second part of the config script will be executed. It looks like there is a difference between the reset performed when OPTION SD TIMING FAST, or OPTION RAM, or OPTION USBKEYBOARD are used and a hard reset of the Waveshare.

So in another thread Peter told me that AUTORUN deliberately doesn't occur after changing an option which requires a reset So instead I'm using this: SEARCH_PATH$ = "/bin/" s$ = Mm.Info$(Search Path) If LCase$(Mm.CmdLine$) = "reset" Or LCase$(Mm.CmdLine$) = "clear" Then Print "OK" option reset ElseIf LCase$(Mm.CmdLine$) = "list" Or s$ = SEARCH_PATH$ Then option list ElseIf Mm.CmdLine$ <> "" Then Error "Unknown command line option" ElseIf s$ = "" Then option f11 "chdir " + chr$(34) + "/zmim/src" + chr$(34) + chr$(13) + chr$(10) option f12 "chdir " + chr$(34) + "/mbt/src" + chr$(34) + chr$(13) + chr$(10) option search path "/magic/" Print "Please run *config again to complete setup" ' This will cause a reset option sd timing fast ElseIf s$ = "/magic/" Then option search path SEARCH_PATH$ Print "OK" ' This will cause a reset option ram Else Error "Unknown state" EndIf It's not especially pretty, but it does the job.
