Re: ftdi_eeprom and FT230X

Here is the full config file

I did change ftdi_eeprom to show debug output:

 ftdi_eeprom_decode(ftdi, 1 /* debug: 1 */);

And here is the full output (when reading back with `ftdi_eeprom --read-eeprom BOB-FT230X.conf` ):

FTDI eeprom generator v0.17

Can you share the full config file and any output from the programming tool? Are you using the stock tool or have you modified it at all?

So I'm trying to set up synchronous bitbang on my FT230X board and am stuck configuring the CBUS pins. I am using ftdi_eeprom built from the latest git sources. I use a config file with the following lines:

cbus0="BITBANG_WR"

cbus1="IO_MODE"

cbus2="IO_MODE"

cbus3="IO_MODE"

However, when I read back the EEPROM I get:

CBUS0 Function: CLK12

CBUS1 Function: CLK24

CBUS2 Function: CLK24

CBUS3 Function: CLK24

It seems that config file parsing refers to the enum ftdi_cbus_func while reading back seems to refer to ftdi_cbush_func...can anyone advise if this is a bug in ftdi_eeprom or libftdi?
