[E3-hacking] Config / content filesystem

New code I don’t know if this is right…??

#!/bin/sh

if (! grep -q /dev/sda1 /proc/mounts); then
 echo "No install media mounted; couldn't find /dev/sda in /proc/mounts"
 exit 1;

echo

echo "This process will completely restore your E3's NAND."
echo This will try and restore The Amstrad firmware on the device. Are you
echo -n "sure you wish to continue? [y/N]: "

read i

if [ ! "x$i" = "xy" -a ! "x$i" = "xY" ]; then
 echo
 echo Aborting.
 exit 1
fi

echo
echo Starting restore.. This might take a while...

perhaps_write_flash()
    {
        p=${1?} erase=${2?}

        dev=/dev/mtd$p

        test -e $f || return

        echo found $f
        echo erasing $erase on $dev
        flash_erase $dev 0 $erase
        echo writing flash

    }

     perhaps_write_flash 0 224

 perhaps_write_flash 2 16

 perhaps_write_flash 4 1728
 perhaps_write_flash 5 48


echo "Finished restoring the Amstrad E3 Firmware,"
echo "Type Reboot or unplug E3 to see if the Amstrad E3 Splash Screen"
echo "comes up (Fingers Crossed) If not just reinstall E3 Linux with the"
echo "pbltool with the -n in the line to stop Handshaking otherwise it will"

Hi Nick,

>  flash_erase /dev/mtd0 0 224
...
>  flash_erase /dev/mtd0 0 16

It always mtd0.  There's too much repetition in the code so errors like
this are likely to creep in.  Consider the approach I suggested in
https://nam03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.earth.li%2Fpipermail%2Fe3-hacking%2F2019-April%2F001314.html&data=02%7C01%7C%7C3698329065b24dc1983108d6c8a3522f%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636917001111275025&sdata=6HxFeGP9mAKyYCGbBLR%2FyibGpJ5zDrlJKtEwH%2FpuZdk%3D&reserved=0
Then the `0' of mtd0, etc., it only typed once.

Cheers, Ralph.
