I have added the board to our list of (un)supported boards (with an appropriate note) and will commit that later together with other small changes. It wont change anything regarding support of the board, but i would like to see the output of flashrom -VV -r image.tmp It will try to read the whole flash chip and will fail and i want to know where. This test is safe. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

That also means the 82802ab unlocking as is can't be used.

Well, it may be more clear to specify exact frequencies, but we may end up with weird set of frequencies for all these large dividers. Maybe it would be better to support a limited set of "standard" dividers and their corresponding frequencies, like: divider | freq --------+-------- 2 | 30MHz 4 | 15MHz 6 | 10MHz 8 | 7.5MHz 10 | 6MHz 12 | 5MHz 20 | 3MHz 30 | 2MHz 60 | 1MHz 80 | 750KHz 100 | 600KHz 120 | 500KHz 150 | 400KHz 200 | 300KHz 300 | 200KHz 600 | 100KHz 800 | 75KHz 1000 | 60KHz 1200 | 50KHz 1500 | 40KHz 2000 | 30KHz 3000 | 20KHz 6000 | 10KHz 8000 | 7.5KHz (and so on) But i vote for supporting specific divider after all, one can never know if there is some obscure device out there in the wild that supports only 6365372Hz. > TODO: man page > --- > ft2232_spi.c | 54 +++++++++++++++++++++++++++++++++++++----------------- > 1 files changed, 37 insertions(+), 17 deletions(-) > > diff --git a/ft2232_spi.c b/ft2232_spi.c > index 122866f..7d598b1 100644 > --- a/ft2232_spi.c > +++ b/ft2232_spi.c > @@ -64,17 +64,8 @@ const struct usbdev_status devs_ft2232spi[] = { > {}, > }; > > -/* > - * The 'H' chips can run internally at either 12MHz or 60MHz. > - * The non-H chips can only run at 12MHz. > - */ > -static uint8_t clock_5x = 1; > > -/* > - * In either case, the divisor is a simple integer clock divider. > - * If clock_5x is set, this divisor divides 30MHz, else it divides 6MHz. > - */ > -#define DIVIDE_BY 3 /* e.g. '3' will give either 10MHz or 2MHz SPI clock. */ > +#define DEFAULT_DIVISOR 2 > > #define BITMODE_BITBANG_NORMAL 1 > #define BITMODE_BITBANG_SPI 2 > @@ -162,12 +153,28 @@ static const struct spi_programmer spi_programmer_ft2232 = { > /* Returns 0 upon success, a negative number upon errors. */ > int ft2232_spi_init(void) > { > - int f, ret = 0; > + int ret = 0; > struct ftdi_context *ftdic =&ftdic_context; > unsigned char buf[512]; > int ft2232_vid = FTDI_VID; > int ft2232_type = FTDI_FT4232H_PID; > enum ftdi_interface ft2232_interface = INTERFACE_B; > + /* > + * The 'H' chips can run with an internal clock of either 12 MHz or 60 MHz, > + * but the non-H chips can only run at 12 MHz.
