3 | # The updater script on the NWZ has a major bug/feature: | ||
4 | # it does NOT clear the update flag if the update scrit fails | ||

10 | # This script remounts the user (aka contents) partition read-write-exec and | ||
11 | # runs the file given and redirects its output and error to a file. | ||
12 | # To use this file, you need to replace NWZ_EXEC_THIS by the file you want to | ||
13 | # execute and NWZ_LOG_THIS by the name of the file you want to log to. You may | ||
14 | # use sed as follows for this purpose: | ||
15 | # cat exec_file_extern.sh.in | sed 's|NWZ_EXEC_THIS|myfile.elf|' | \ | ||
