umount /mnt/ufdisk fsck /dev/ufdisk mount /mnt/ufdisk For proprietary RTOS, use the manufacturer’s flash repair utility. If the device allows it and you have a backup of configuration, perform a factory reset. This wipes the ufdisk and recreates the default directory structure.
Introduction Encountering a storage error on an embedded device or legacy hardware can be frustrating, especially when the error code seems cryptic. One such error that has puzzled technicians, industrial machine operators, and retro-computing enthusiasts is the “au87101a ufdisk full” message. au87101a ufdisk full
Check for files named core , core.* , crashdump , or assert.dump . If the system is stable, delete them: Introduction Encountering a storage error on an embedded
By following the diagnostic and remediation steps in this guide, you can resolve the error in minutes, restore normal operation, and prevent it from coming back. Always remember to back up important data before making deletions, and consult the device’s technical manual for any model-specific nuances. If the system is stable, delete them: By
logrotate -f /etc/logrotate.conf # If present Alternatively, compress large log files (if you must keep them):
cd /mnt/ufdisk/logs rm -f *.log.?? # Remove rotated logs rm -f *tmp rm -f crashdump_old* : Do not delete current log files if you need them for auditing. If unsure, move them to an external backup first. Solution 2: Clear Core Dumps and Crash Files Embedded systems often write core dumps to ufdisk . These can be hundreds of MB.
find /mnt/ufdisk -name "*.bin" -o -name "*.hex" -o -name "*.partial" Cross-check with current firmware version. If the file is not the active image, delete it. Some devices have a built-in log rotation script. Run it manually:
