<div>Yes I know they are but mtd0 is where boot (like the bios on a PC) would be so PBL or Uboot would be there.<br>

<div>I videoed the install but I shorting it so its like 22 minutes long. Its took about a hour and a half to do, the backing up of the E3 took the longest, flashing Linux took about 2 to 3 minutes because the OS is not very big. but if you want Linux on your
E3 you don’t need to install it, the Installer is a ramdisk so you can test it on that. Its like FEL mode. I just want to record it for my channel on You Tube and false me to have to restore it. </div>

<div>flash _erase line I got from this site but it will not delete the right amount of blocks.<br>
So 16 units make the block size 131072 so what is the unit for block size 16384,mtd0 to 5 are all the same block size..?? I am not great at maths…lol<br>

<div>Thank for the help Ralph..😊 Once I get this working again I move on to the E2(Amstrad

<br>
Aren't PBL and Uboot two distinct separate things? PBL was written by<br>
Clive at Amstrad. On the E2, it's the sole occupant of the small 64 KiB<br>
flash so it isn't at risk of corruption when it writes to the main 8 MiB<br>
flash.<br>

<br>
If you have extracted the contents of those partitions then start poking<br>
around their contents. file(1), hexdump(1), etc. And Google some<br>
resources on reverse-engineering flash blobs to identify their contents.<br>

<br>
I think Clive wanted to take advantage of Linux for the E3, given its<br>
higher, more complex, workload and thus needed the MMU.<br>
