The source code is available via Git $ git clone -b v1.1 https://review.coreboot.org/flashrom-stable.git or as a tarball: https://download.flashrom.org/flashrom-stable/releases/flashrom-stable-v1.1… Daniel, I've never looked into ebuilds, I suppose it could be easily adapted, though. If you want to build it manually, check [1] for prerequisites. I suggest that you make a backup first and try to confirm its consistency before any write attempt. With some luck, there are some markers visible in a hexdump. At *20000 you may see "aa 55 aa 55". And probably in the very last line some pattern with 90* e9. The latter is legacy, though, and may not be there. This is from one of my AM4 boards: $ hexdump -C /tmp/dump | grep -E '0000 aa 55 aa 55|fff0 (90 )+.*e9' 00020000 aa 55 aa 55 00 00 00 00 00 00 00 00 00 10 02 ff |.U.U............| 00fffff0 90 90 e9 03 e9 00 00 00 fc 00 00 00 00 00 d0 ff |................| Cheers, Nico [1] https://www.flashrom.org/Downloads

[announce] flashrom-stable v1.1
by Nico Huber 03 Apr '23

03 Apr '23

Hi folks, after a little more (boring) testing, the v1.1 release is ready and tagged. 281 commits went into this release. About 200 of them were cherry-picks from the original master branch. After those, regular development continued, mostly adding more programmer drivers. # What changed * The buildsystem integration was almost re-written. The Makefile looks a lot cleaner now, and Meson is ready to be used on more than just Linux. * Two new programmer drivers were added: `ch347_spi`, `linux_gpio_spi` * The `dirtyjtag_spi` driver is DJTAG2 ready. * The `internal` programmer has a new driver for AMD's SPI100 controller now. This was tested with different chipset confi- gurations on Pinnacle Ridge, Raven Ridge, Matisse, Vermeer, and Genoa(!) :) * And the usual smaller refactorings and other changes. # Download The official tarball + signature live on flashrom.org now: https://download.flashrom.org/flashrom-stable/releases/flashrom-stable-v1.1… https://download.flashrom.org/flashrom-stable/releases/flashrom-stable-v1.1… And of course, there's the Git tag `v1.1`. # What was tested recently: * external SPI: ch347_spi, ft2232_spi, dirtyjtag_spi, buspirate_spi, serprog (w/ stm32-vserprog, SPI flash), pickit2_spi, jlink_spi, usbblaster_spi, ch341a_spi, linux_spi and linux_gpio_spi * internal: SPI on Intel ICH7, ICH9 (hw&sw sequencing), PCH7, and APL, Parallel through VIA VT82C686 southbridge Cheers, Nico
