  • Patch Set #32:

    I wondered what device was used for testing so far and […]

    Thanks for your effort!
    hm, I´m not sure what´s wrong. Saving a few seconds is not what I was looking for...

    Some information:

    • the 1,36MHz on the screenshot is wrong (sorry for missleading!!) It´s the distance between the cursors which may be placed arbitrarily
    • I´m using default divisor and on my osci screenshots taken last week that results in something between 25-30 MHz (did not measure, but estimate from screenshots)
    • lsusb says bcdDevice 7.00 as well
    • I run: `make CONFIG_ENABLE_LIBUSB1_PROGRAMMERS=no`. So I´m not using libusb 1.0 maybe this leads to some difference?
    • I´m doing tests on my side with an N25Q128..3E chip (has quite the same parameters as W25Q128FV")
    • I´m running flashrom on a virutal machine (don´t think this makes any difference)
    • at SPI-Bus level the multicmd+chunk4k looks much better and faster (i.e. less bursts) so I have no idea why this should not lead to an overall speed increase... (regardless of the setup)

    
    NB: yepp, I noticed that with the erase block size, as well and have it on my todo list. I was thinking about something like comandline parameter to select block size or an extra parameter at flashchips.c to mark the preferred block size. May be we should open a new patch for that to discuss ideas... (it was just because of lack of support for this patch for month why I did not step further)
