It is released under -the terms of the GPL. The purpose is to let you write to the bootrom of -the SMC9462TX card. The assumption is that you've stuck an AT29C512 in the -socket. Note that the board has pins D5 + D6 reversed on the socket. Also -the socket only supplies 3.3V to the rom. Good luck trying to locate a -DIP programmable flash device that operates at 3.3V. What I do is to bend -pin 32 back and solder a wire directly from the 5V side of the 3.3V regulator -over to it. The dp83820's bootrom interface pins are all 5V logic tolerant. -However mod your board at your own risk, no warranty or guarantees are implied -or given!!! If you don't wire the 5V to the AT29C512, you can still read -the rom contents (it operates ok at 3.3V evidently) but you can't write to it -because the AT29C512 has a safety protection, it disables writes if the -power supply voltage drops below 3.8V. - -See the comments at the top of the 2 C files for more information. - -The Makefile needs to be hacked to build for your system. If you can't -figure it out you shouldn't be messing with this stuff anyway. - --Dave Ashley -Email address intentionally left out to avoid spam. -http://www.xdr.com/dash - -Mon Mar 8 13:55:34 PST 2004 |
