permission denied uploading on linux

[jerabaul29]

Hi,

I get some denied permission errors when trying to upload successfully compiled sketches to an Apollo Red board on Linux (Ubuntu 20.04). I wonder if there may be some need to updates some udev rules? Any idea on this?

Thanks :)

(sorry, I think the true name is Artemis red board; anyways, this one:

I tried to fix the access, but still not working. At the moment:

~$ ls -l /dev/ttyUSB0 
crw-rw---- 1 root dialout 188, 0 des.  11 13:35 /dev/ttyUSB0
~$ whoami
jrmet
~$ groups jrmet
jrmet : jrmet adm dialout cdrom sudo dip plugdev lpadmin lxd sambashare

So I would guess writing access should be ok (?), but I still get the error:

Sketch uses 118300 bytes (12%) of program storage space. Maximum is 983040 bytes.
Global variables use 27712 bytes (7%) of dynamic memory, leaving 365504 bytes for local variables. Maximum is 393216 bytes.

An error occurred while uploading the sketch

Ok, after some more debugging, the problem was that the program in charge of uploading the firmware did not have execution rights. I did:

~/.arduino15/packages/SparkFun/hardware/apollo3/2.0.3/tools/uploaders/asb/dist/linux$ chmod +x asb

and now it seems to be able to (try to) upload.

[jerabaul29]

Do you think there is a way to update the rights on the asb utility installed by the board manager in linux? :)

@jerabaul29 thanks for reporting this. we will correct the file permissions. please respond here if you find any more related issues.

@Wenn0101 we should investigate what happens to file permissions in and between these steps:

• generation of executables from the respective uploader repositories (ASB, SVL)
• inclusion of executables via submodules in the arduino core
• compression / archival of the arduino core as it is published to a release

I updated to 2.0.5 today. The issue is still here (it even came back when the non-executable uploader replaced the old uploader that I had made executable).

Nothing bad for me to fix, just a small chmod +x, but for less experienced users this may be a hazzle.

[oclyke]

hit the same issue on fresh install of v2.0.5 (macOS)
seems that the PRs for a possible fix were approved but never merged:

• add executable permissions Apollo3_Uploader_SVL#2
• add executable permissions Apollo3_Uploader_ASB#3

@Wenn0101 when you merge these PRs they will trigger a re-build of the tools. the new tools will be merged into the main branch automatically (I think - you should double check). when that is complete you'll need to update the submodules used in this core so that the latest tools are pulled in.
