See the first line of http://www.earth.li/%7Enoodles/files/delta.boot (linked from http://www.earth.li/~noodles/hardware-e3.html). Hope this helps, Antony. -- All generalisations are inaccurate. -- I'm not impossible, just highly implausible. Please reply to the list; please don't CC me.

Hi, Bought an E3 back in 2008 Not done much with it till now. Wanted to start developing on it again but the files on the ftp server are only up to 2.6.19 and muru only has upto 2.6.27. Can anyone provide me with the latest kernel patch / buildroot config files?

I've got an amstrad emailer em2001uk that is locked up and unusable - 'Hold down (email) button to restore service', so I'm here as a beginner to see what I can do about it. All I want is to use it as an ordinary phone. I know my way a bit around a linux pc if that helps. Thanks for any advice.

pbltool problem
by Edward Robbins 26 Nov '12

26 Nov '12

Hi again, I've got some free time today and have been playing with the emailer again. I've managed to build a 3.6 kernel a while ago but when I tried to upload the V2 stuff I had problems. Today I made up a new cable thinking that might be the issue, but it hasn't helped. I can get a boot log just fine, but when I run pbltool with "sudo ./pbltool -f /dev/ttyUSB0 oe-install.pbl" I get: Prodding... Handshaking... Done handshaking Compressed return block? Flushing: 0x00 Flushing: 0x0E Flushing: 0x00 Flushing: 0x82 Flushing: 0x00 Flushing: 0x52 Flushing: 0x00 Flushing: 0x04 Flushing: 0x09 Flushing: 0x1F Flushing: 0x05 Flushing: 0x10 Flushing: 0x40 Flushing: 0xFE Flushing: 0x7B Flushing: 0x0E Flushing: 0xB0 Flushing: 0x9A Compressed return block? Which then repeats forever. I've tried editing oe-install.pbl to change the baud rate (38400, 19200, 9600) but it makes no difference. I also looked for pblq but the link on http://cowlark.com/amstrad/index.html is broken. Any ideas? Thanks!
