  • Patch Set #1, Line 9: FT232H-based devices are unable to read over 256 bytes of flash in one

    So, with the 1536B chunk size, do you always get full URBs succeeding? i.e. […]

    When the URB requests succeed, yeah, they are always 1536 bytes. And the last URB_BULK in reports -ENOENT.

    The only thing I am powering via the FT232H board is the flash chip, yeah. The chip is standalone in a socket that is only attached to the FT232H board.

    Using forced mode without the flash, I don't get any RX packets once it starts attempting to read the flash. It attempts a 1536B URB_BULK in request, but it just gives a -ENOENT a few seconds later. Using -f _with_ the chip installed it gives similar results to not using -f. This is the command I am using for reference:

    ./flashrom -p ft2232_spi:type=232H -c "W25Q80BW" -VVV -r dummy.rom -f
