failure to write image to emmc via Ethernet connection

[KE8SOJ]

I encountered this error when attempting to write an image to a VIM3 which was built using the Manjaro buildarmimg tool and prepared with khadas-rescue-tools.

head: cannot open '/tmp/kwrite_http.862834.log' for reading: No such file or directory

The suggested solution I found to the curl: option --data-binary: out of memory issue is to pass the "-T " option to curl. Once I modified the curl option in /www/tools/kwrite I was able to write the image to emmc over Ethernet.

LOG=/tmp/kwrite_http.$$.log                                                  
[ "$IN" ] && {                                                               
echo "[i] $IN ($ext) write => $krescue // $DST">&2                           
#curl --data-binary @"$IN" \   
curl -T "$IN" \                                              
    -o $LOG \                                                                
    $krescue/api/disk/write/$DST$ext                                         
head -n20 $LOG                                                               
}              

BTW thank you for developing this awesome tool!
