Author: stefanct Date: Sun Jan 24 00:27:58 2016 New Revision: 1918 URL: http://flashrom.org/trac/flashrom/changeset/1918 Log: dediprog: support new communication protocol, cleanup and enable by default. The new protocol changes some commands, so adjust the code to support these. Use helper functions to reduce duplication in libusb calls. Testing with real hardware showed that the maximum read size via the control endpoint is about 16 bytes although specification does not mention that. Dediprog SF600 is not supported yet. Based on the following chromiumos changes: Change-Id: Ibd1e27d9e8273ba879b9b5d95675b99596255c89 Change-Id: Ifc33e7b1eed5b0cb80f83458fa24741a577fa46a Additionally, some ideas from Alex for cleaner code were incorporated as well. Tested on an SF100 V4 with both firmware generations PREWing a M25PX80 and AT45DB041D (the latter is using dediprog_spi_send_command() instead of optimized functions which make it a good test vehicle).

Hello, I wanted to contact with you earlier about the buspirate write failure, just I have forgotten it I have also had problems with different external programmers and a the solution was adding a 100nF capacitor right next to the SPI flash.

You might be interested in https://www.coreboot.org/FlexyICE I have just discovered that project a few weeks ago myself so I cannot give much more information than that. It is probably not purchasable anymore but open enough that one could build something new from that. Sooner or later I am planning to give a related projected out as Bachelor or Master thesis but that will take a while (and would probably be SPI-related). -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

To follow this up: Linux exposes same mixed behavior as NetBSD earlier, e.g. erase+write sometimes could be completed successfully, sometimes erase procedure just messes PROM contents as mentioned before. Software environment and operating voltage are absolutely stable between those tries so this is almost surely a timing issue in the prom chip itself or mis-engineering in its electrical neighborhood which results in a protocol violation. This is just for information, I do not own any hardware which `ll be able to prove or disprove this hypothesis by measuring data on a parallel interface directly, BTW, are there still any FWH-capable romulators in production? Looks like most of sockets from this era has been designed without bearing in mind possibility of the in-scheme reprogramming, but the only romulators I`ve seen on ebay are ancient devices bundled with software on floppies...
