Linux 64 bit Flasher to board - LinjingZhang/XMC-for-Arduino GitHub Wiki
On 64 bit Linux (ubuntu etc..) it has been reported that the XMCFlasher does not work out of the box.
See Issue =21 on Infineon/XMC-for-Arduino
The suggested fix is to put a symbolic link in so the 32bit application can be found properly as suggested by PabloPL there as follows after installing the Segger software.
ln -s /opt/SEGGER/JLink/libjlinkarm.so /usr/lib/libjlinkarm.so
This enables the XMCFlasher to run.
The problem appears to be in the Segger software installation.
