So no way of backing up the Nand then ..?

I'm not kidding about it being slow --- it's only a few bytes per second. PBL doesn't have a command to read data, so what pblq does is to tell it to checksum one byte at a time, and it figures out what the byte is from that. It's strictly a hack.

You don’t have anything on the program you made pblq..? This is the bit I want to get working.. “readflash <filename> <offset> <length> Reads data from the NAND flash (very, very slowly)” What's the offset and length, I don’t know what that means..?

I have managed to dig up this old Getting Started page, with instructions on reflashing the E3 with Linux: https://wiki.earth.li/E3_Getting_Started<https://nam01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwiki.earth.li%2FE3_Getting_Started&data=02%7C01%7C%7C7c55375aea6a4a77e90508d6bb9f2cdf%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636902689655542999&sdata=H2PLBCxlm0DisFSVtC2GXqxPWeeLAzOU8bAz1HIRXXY%3D&reserved=0> Remember that we were all interested in running stock Linux on the machine rather than hacking the built-in firmware. Those instructions are all based around pbltool, which was the other tool for talking to PBL and which I'd completely forgotten about, but should work fine. Bear in mind that this will replace the stock firmware. Regarding forums... I've never met a forum yet which was as easy to use as email, let alone coming close to the convenience of getting messages delivered directly to my inbox. (If this had been a forum I would never have seen your posts!) Have you seen the mailing list archives at https://www.earth.li/pipermail/e3-hacking/<https://nam01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.earth.li%2Fpipermail%2Fe3-hacking%2F&data=02%7C01%7C%7C7c55375aea6a4a77e90508d6bb9f2cdf%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636902689655553004&sdata=MBwkP77N8Af1BpvQS%2BXHA50Aebe1omhbjFRwwEjebow%3D&reserved=0>?

Like “ writeflash <filename> <offset>” I don’t understand what is offset and length is ,is length the size of the NAND..???? I am don’t know about pbl commands..???

You have been warned!” This needs a manual on how to use it properly,some I understand not all. I have notice there is not a lot of info on flashing the emailer and its not explained well, its like you put it up to show you have hacked it, but how do you expected to do it yourself, I have looked there is nothing on how to read the NAND from the E3,please someone make a walkthrough or explain offset and length..? Not beaning funny but posting on here is hard, I have never used email so much,well I don’t use email, I know people on here don’t like Facebook so what about a Forum so all info can be in one place not scattered over different websites, it very hard to look up any thing in the Mailing list Archive because it has no search options so you have to press on each thread one by one. Would you be happy If I make a forum for the Emailer, no point me making one if no one uses it..?? I am proberly 8 years to late…lol, I am good at making them, I make one for TheC64 Mini. http://thec64community.online<https://nam01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fthec64community.online&data=02%7C01%7C%7C7c55375aea6a4a77e90508d6bb9f2cdf%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636902689655563015&sdata=77fvUVmw5y677FSsw5KgXBYO7FZtm984vri4E%2FR6jkg%3D&reserved=0> I think I know why you made the E3 Hacking Mailing list because you could at the time look at it on the Emailer by redirecting the emails to your email addy on Amserve.… 😊 would of cost a bomb to look at it at the time at 20p a collection. I only connected email once a day when I was using it and that was about £6.20 a month so it cost about £75 a year just to have it turn on…lol Thanks..
