That's easily discoverable (and copyrighted) so we won't include it. However, I was not able to find out how the circuit is powered (most information sources are in russian and translating them automatically was not enough to find out :). I presume Vcc is connected to an external power source, right? -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

[commit] r1945 - trunk

Author: stefanct Date: Sun Feb 28 18:04:38 2016 New Revision: 1945 URL: http://flashrom.org/trac/flashrom/changeset/1945 Log: rayer_spi: add support for SPI Tiny Tools-compatible hardware. Apparently, there is at least one board of Russian origin (coined SPI_TT LPT) that works with SPI Tiny Tools which is a closed-source Windows GUI program somewhat similar to flashrom.

The patch alone is no proof but if you have tested it with real hardware and it worked then there is no reason to not believe you and mark it as tested. Have you run flashrom with your patch on that hardware and did writing work? > It doesn't need any enable routine - it has no logic, no triggers/relay - > just resistors and buffer. Buffers most often have disable (or enable) pins and if they are not pulled down (or up) statically by resistors we need to do that dynamically when starting to access the programmer. This would not be unusual at all for this class of programmers... hence my question. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Please post a proper patch according to our development guidelines next time: https://www.flashrom.org/Development_Guidelines I have prepared a patch as you suggested and even included an entry to the manpage. However, I wonder if you have tested your file successfully because the tested field was set to NT instead of OK. Also, doesn't it need any enable routine like the byteblaster? -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

[PATCH] ch341a_spi: provide nACT/ACT with CS1/2 for ISP use

The only real reason for having flashchips.h is having a nice overview of IDs and relevant information thus that comment is perfectly fine there - it would get lost in the shuffle in the .c file. We have lots of similar comments in the .h file, most prominently the one for the GIGADEVICE_GD25Q128 that the above was copied from ;) -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner
