[announce] flashprog v1.2 is ready!

Hi all, I'm happy to announce the flashprog v1.2 release. This one should be particularly interesting for developers: We have finally added the first bits for multi-i/o fast reads and QPI support. QPI works well with a new driver for programmers based on the FT4222H. Dual- and quad-i/o reads are also implemented for the Dediprog SF600 and its successors. Of the latter, the SF600Plus-G2 is fully tested. Other versions, using the same protocol, should work as well. Dual-i/o is enabled by default for these. With all four i/o lines connected, quad-i/o reads can be enabled with $ flashprog -p dediprog:iomode=quad (don't forget to also set the `spispeed` to go even faster) SF600 models that use older protocol versions should work as well but are untested. For those, `iomode=dual` is necessary for dual- i/o. Test reports are most welcome! See also the full release notes at [1]. The code is available in Git[2] (tag `v1.2') and as tarball[3]. After the release is before the release, and we are currently loo- king for testers of new chipset support: On the Intel side we have patches prepared for Snow Ridge, Meteor Lake, and Emmitsburg (PCH) (newer Xeon-SP systems) [4]. For AMD, everything up to and including Zen 4 is supported as long as the chipset is not too locked down. More testing here would be welcome, though, so we know what configurations vendors ship. Happy flashing, Nico [1] https://flashprog.org/wiki/Flashprog/v1.2 [2] https://github.com/SourceArcade/flashprog [3] https://flashprog.org/releases/flashprog-v1.2.tar.bz2 [4] https://review.sourcearcade.org/q/status:open+topic:moar_ichspi

Preparing for flashprog v1.2
by Nico Huber 18 Aug '24

Hi all, we're preparing for our next release v1.2 [1]. This one should be particularly interesting for developers: With multi i/o and QPI support, and the right programmer, external flashing can be a lot faster now. There's a new driver for FTDI FT4222H USB-to-SPI bridges -- probably our fastest supported programmer -- and Dediprog SF600 users benefit as well. Please grab the RC and test it :) As usual, the code is available through the tag `v1.2-rc1', and as tarball [2]. Cheers, Nico [1] https://flashprog.org/wiki/Flashprog/v1.2 [2] https://flashprog.org/releases/flashprog-v1.2-rc1.tar.bz2

Hello, While I was trying to internally flash the bios chip I step in this issue. I am nowhere near a programmer or computer literate, but I followed step by step the documentation. Are you familiar with this issue?
