crc32appender now needed for RRF?

I copied it to the root folder of the RepRapFirmware directory. Does not work

It has to be a directory in your $PATH.

@gtj0

I get this:

/bin/sh: crc32appender: command not found

dont know where my $PATH is

wilriker

@smoki3 in the command line type

echo $PATH

it should give you a colon-separated list of directories where the system looks for executables by default.

@wilriker Your commit to add it needs to add the appropriate Tools/crc32appender directories to the PATH in Eclipse or we'll have to manually copy it to a system directory.

I just realized that this will be very complicated since the binaries all have the same name but need to be different for the different operating systems.

@wilriker

echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/Users/kevin/.android-sdk-macosx/platform-tools/:/Users/kevin/Library/platform-tools/

I added it to the /usr/local/bin

but it does not work in ecplise.

In the terminal it works

You may be able to rename the directories to match some Eclipse or environment variable. I think there's a variable in Eclipse named "platform" or something close then you could add the path as ${workspace_dir}/Tools/crc32appender/${platcorm}

Not sure if those are the exact variable names.

I just put in the same /bin directory that I put miscellaneous binaries in, which is already on my PATH. This is under Windows 10 x64.

@smoki3 I also put it in /usr/local/bin and it worked from Eclipse. Did you restart Eclipse? You shouldn't have to but it may help.

You can also try running "make" manually...
From the output directory (Duet2_RTOS, Duet3_V06, etc), run make clean and make and see if that works.

@wilriker These look like they could be good variables to use:

HostOsName
OsType
target.os

@gtj0

Its funny, in the terminal it is working with make... In eclipse not

I figured out that eclipse only uses:

/usr/bin:/bin:/usr/sbin:/sbin

But on the mac we dont have permissions to add files to these folders

Any why to add another path to $PATH?

dc42

The Windows version of Eclipse lets you set up the search path within Eclipse. Does the Mac version offer the same?

What does this tool do? I still get the .bin I want.

I get an error when building:
arm-none-eabi-objcopy -O binary "C:\eclipse\Firmware\RepRapFirmware\DuetM_RTOS/DuetMaestroFirmware.elf" "C:\eclipse\Firmware\RepRapFirmware\DuetM_RTOS/DuetMaestroFirmware.bin" && crc32appender "C:\eclipse\Firmware\RepRapFirmware\DuetM_RTOS/DuetMaestroFirmware.bin"
c:/program files/gnu arm eclipse/build tools/2.6-201507152002/bin/sh: crc32appender: not found

Building again the error goes away, there is an depency error in the makefiles.

wilriker

@bondus It adds the CRC32 checksum to the end of the generated binary. The firmware updater checks for that. It will certainly complain if it's wrong but I don't know off hand what it does when it's missing.

dc42

The firmware will stop at boot up and flash the Diag LED if the CRC is wrong.

bondus

@dc42 that crc protection certainly worked, I had to use SAM-BA to get my board back. It would be nice if the flasher-updater in the firmware also checked the CRC before updating.

Good idea, I'll add this to the work list.

bondus

Checking the CRC in the upgrader will limit downgrading though.

And adding the PATH in the dev environment to that tool is missing in the description on how to build the firmware. It's hard enough already to get RRF to build.

AJ Quick

I'm having the same problem with crc32appender not being found in Eclipse.

I had to run it manually from the command line after the binary was generated.

Not sure what I need to do to tell Eclipse where to look for the file though.

gtj0

Oddly enough, the instructions are in BuildInstructions in the dev and v3.01-dev branches but not in the v3-dev branch.

You need to copy the appropriate binary from Tools/crc32appender to someplace in your system PATH or update your system PATH to point to the directory where the appropriate binary is located. If you're on Linux, you can just copy Tools/crc32appender/linux-x86_64/crc32appender to /usr/local/bin.
