Date: Fri, 1 Aug 2003 00:37:44 +0200 (MEST) Hey, now I can flash my box, too. Before I had borrowed/exchanged the CPU PCB with a friend. After a lot of suspense, I got 5 samples of SST39VF040 chips in the necessary TSOP32 package. I've soldered one into my box, see here: http://joerg.hohensohn.bei.t-online.de/archos/flash_upgrade.jpg Another one I'd like to keep as spare, the remaining three I can offer to people who 1) have the wrong kind, 2) are so desperate to flash that they would do this difficult mod 3) are skilled to do it (I used a stereo microscope and a fine solder needle) 4) have or can do the serial mod including level converter, plus UART boot mod This really is not for beginners. It requires to separate the boards, because the flash is on the inside. The chip itself has 0.5 mm pin grid, the finest I've ever worked on. To program it, you either need a programming device capable of that chip in that package, or the UART boot mod, which in turn requires the serial mod. I went the latter way, proving once again that the UART boot can work you up from an erased chip. I will document this mod with a picture soon. So, once again, if you are really capable and will actually do this, contact me. The chips were hard to get, I'd like to give those only to people were they won't settle dust. (And I don't want them to settle dust at my place either.) Is there's anybody with access to a suitable programming device (including TSOP32 adapter)? That could make it easier for the folks following this, we could prepare the chip, no need for the serial stuff then.
