Author: hailfinger Date: Fri Nov 4 22:35:26 2011 New Revision: 1459 URL: http://flashrom.org/trac/flashrom/changeset/1459 Log: Add opaque programmer registration infrastructure An opaque programmer does not allow direct flash access and only offers abstract probe/read/erase/write methods. Due to that, opaque programmers need their own infrastructure and registration framework.

The message is some test from the chip which is telling if some chip is connected or not. Try to override that or check the datasheet to see what it really does. Thanks Rudolf

SST49LF080A - ERASE FAILED at 0x000a3d28!
by Rudolf Marek 03 Nov '11

03 Nov '11

Hi all, It worked with this chip some time ago (a year). Erasing with -E also fails but the next one will succeed. If I write back content again and do it all again I can reproduce this. It seems like a timing issue. Log attached. Changing probe_timing to 10000 is not helping. Tried with latest flashrom, older ended with SIGSEGV. Any clue? Thanks Rudolf

Absolutely agreed. The only possible generic problem with that approach would be the registration of multiple ICH-style SPI programmers, but unless we see boards with two active ICH-style southbridges I think we can assume the static variable handles it well. (Note that boards with multiple MCP55 southbridges exist, but only one southbridge has an attached flash chip.) There might be an issue for those who want to use flashrom as a standalone tool (e.g. on top of libpayload) where heap allocations for static variables are unwanted, but that's a huge can of worms and I'd rather ignore that issue until either static variables work well in that environment or until someone hacks a way around static variables being a problem there. > the type member is enough most of the time to derive the wanted > information, but > - not always (e.g. ich_set_bbar) > - only available after registration, which we want to delay till the end > of init. > - we really want to distinguish between chipset version-grained > attributes which are not reflected by the registered programmer. Indeed. So if you could rework the patch to use your static variable suggestion, it would reduce patch size and make the code more readable.
