Troubleshooting
General procedure
Make sure your Flasher is working as expected. See the troubleshooting section
in the Flasher manual.
Ensure that the target hardware matches the project file settings. Pay special
attention to the following aspects:
- RAM address
- Flash base address
- MCU
Try to program your target device using a sample project file if available. J-Flash
ships with an extensive number of project files for many target boards. See sec-
tion Sample Projects on page 14 for a complete list of project files.
Typical problems
Failed to connect
Meaning:
This error message is shown if any error occurs during the connection process.
Remedy:
Make sure the target is actually connected to Flasher STM 8 and powered. Verify the
correct connection between target and Flasher.
Blank check failed
Meaning:
The target memory was not empty during blank check.
Remedy:
Erase target memory.
RAM check failed
Meaning:
No RAM found at the specified RAM location.
Remedy:
Make sure a correct RAM address is specified in the project settings. See section CPU
Settings on page 22.
Unsupported flash type / bus width
Meaning:
The target flash memory or the bus organization is not yet supported.
Remedy:
Inform us about the device you want to use. SEGGER is constantly adding support for
new devices.
No matching RAMCode
Meaning:
There is no programming algorithm available for the selected target memory type.
Remedy:
Inform us about the device you want to use. SEGGER is constantly adding support for
new devices.
