first, need to affirm the SD card is “writeable”, operate the step as follow:
(1) ssh login router system;
(2) execute cmd:
ls -l /mnt/
(check the /mnt/sda1 is mount OK, catch the picture)
(3) goto /mnt/sda1 directory, create one file, check is ok:
cd /mnt/sda1
echo “abc” > test.txt
ls -l ./
check the file test.txt if create ok? catch the picture
================================================
first, check the SD is writeable, if the SD card can’t write, have to format the SD card again.
advise format the SD card format is: NTFS
