incorrect way to open application with python

[ninjaboy667]

Description:
PC is running on local admin.

Code was pulled straight from the XMC 1100 sleep example file:

https://github.com/Infineon/XMC-for-Arduino/tree/master/libraries/DeviceControlXMC/examples/SleepModeXMC1100

Steps to Reproduce:

1. install Jlink, Arduino IDE, install XMC board manager 3.0.0 on arduino

2. Copy example files, attempt to upload

Expected Result:

permission denied

Actual Result:

**Frequency (1/1)

Windows 10

Arduino IDE 2.2.1

Fixed
Please add in the documentation that the Arduino IDE needs to Run as administrator in order to use the XMC-flasher.py.
A prompt could probably be added, or there surely is some way to run this without admin privileges ? @boramonideep

Hi @ninjaboy667,
Thanks for submitting & elaborating on this issue.

We will definitely look into this and improve the docs, or better - find a way to run this without admin privileges.

Best regards
Julian

The problem is this code:

XMC-for-Arduino/tools/xmc-flasher.py

Lines 71 to 74 in bed41f4

	def create_jlink_erase_command_file():
	cmd_jlink = 'cmd.jlink'
	with open(cmd_jlink,'w') as f:
	f.writelines(['r\n', 'h\n', 'erase\n', 'exit\n'])

Is creating the cmd.jlink file in the current working directory. That is whatever path Arduino IDE was started from. It is common to install Arduino IDE in a path like C:\Program Files\arduino-ide and Windows imposes special security restrictions on this path, which causes the creation of the file to fail with this "Permission denied" error.

The solution is to adjust the xmc-flasher.py code so that it sets an absolute path for the cmd.jlink file instead of dumping it into whatever happens to be the current working directory. An appropriate path should be used for this purpose. Since this is a temporary file, it should be created under the system temporary folder.

Hi @per1234

Thank you very much for this hint.
Yes, the download path creates permission problems if the Arduino IDE is installed for all users of Windows. We will fix this in the next release. @ninjaboy667

This was resolved in release 3.3.0, so close this issue
