Title: C3000 can't update when the microdrive is missing
Post by: DiTBho on May 16, 2025, 09:13:34 am

hi
I am developing my own bootloader, supporting
- C1000
- C3000

yesterday I prepared an SD card
- PC partition FAT16
- mkfs.fat

then I copied
- update.sh
- zImage <----- my application

I followed the instruction to enter the Sharp Menu.
As result:
- C1000 perfectly flashed, now it boots my bootloader
- C3000 says it can't update anything "because the microdrive is missing". No option.

I removed the microdrive because it was faulty, the C3K is designed to boot completely from the SD card. I still need to find and buy a replacement for the internal MD.

It's absurd that update.sh refuses to flash because the microdrive is missing ...

Any workarounds?

I guess the simplest way to fix this is to by editing the update.sh script to remove the need for the microdrive. The file itself is encoded with a simple character substitution algorithm, here's a simple program to encode/decode it: endecsh.c at the bottom of this page:

I have tried to make a mirror of the page with httrack but it was unsuccessful, I'll try again.

        echo 'MODEL: '$MODEL 'is unsupported'
        echo ''
        echo 'Please reset'
        while true
        do
        done
        ;;
esac

I wonder what the point is in coding a script that absurdly...
In any case, this is where it probes for the microdrive.
