Reading/Writing FT4232 EEPROM

Hi Ori,

Post by Ori Idan
I have a FT4232 mini module and I want to read/write it's EEPROM.
I tried the utility ftdi_eeprom (on Ubuntu 12.10)
It gave me an error on product_id so I changed it to 0x6011
It then gave me an error on BM_type_chip I commented out this line
I then tried to write the EEPROM it looked like it did but when reading
the EEPROM back I get Checksum Error: 84c1 0000
It seems that ftdi_eeprom is not compatible with FT4232
How do I write the FT4232 EEPROM on Linux?

which version of ftdi_eeprom does Ubuntu 12.10 ship?

You could give the git HEAD version a try, it _should_ work.

Look up "libftdi" in your package manager GUI...

OR

do something like this from a terminal:

# dpkg -l | grep -i ftdi

My Ubuntu 12.10 reports libftdi as version 0.20

The output shows that you are running libftdi version 0.20 on a 32bit
platform (i386)

PS: I haven't followed your conversation deeply on the list but it
should be fine - if you are aiming for the functionality in the libftdi
version 0.x series releases.
If you need something newer eg libftdi 1.x functionality - you need to
build the library yourself from the ftdi github trunk.

I have to program the EEPROM and tried using ftdi_eeprom but it did not

That's what started this whole conversation.

I still did not find a solution how to program EEPROM on FT4232 I am using Ubuntu 12.10 with libftdi1 0.20

Having had the same problem I have modified the eeprom example (see attached program). For my setting it is sufficient
to read and write binary data, since I only have to set a known configuration.
To get the binary data I used the windows configuration program from ftdichip
(http://www.ftdichip.com/Support/Utilities.htm#FT_Prog) to program the eeprom and read it using eeprom-set on linux.

Hope that helps

Greetings
Andreas

You could give the git HEAD version a try, it _should_ work.

the HEAD version indeed works; FT4232 support was added last year.

You can use ftdi_eeprom from HEAD (or v1.0) to program the chip
and still use 0.19/0.20 from your application as long as the application
doesn't use any ftdi*eeprom*() function.

(sorry for joining the discussion so late - I was away on vacation)

I tried developer.intra2net..com and all I could find was sources of
libftdi, after compilation it gave me ftdi_eeprom ver. 0.13

So how to I find the right sources and finally be able to read and write
the EEPROM?

in HEAD (and 1.0) ftdi_eeprom is included in the libftdi package.

The download page is:
http://www.intra2net.com/en/developer/libftdi/download.php

the source package of 1.0 is:

http://www.intra2net.com/en/developer/libftdi/download/libftdi1-1.0.tar.bz2

and you can even follow the HEAD development in Git here:

This gives me version 0.17 of ftdi_eeprom while the Ubuntu system by

I tried it anyway and it does not work as well.

I am probably doing something wrong.

correct, ftdi_eeprom 1.0 indeed presents itself as 0.17 ... (perhaps we
should update the version number ;-)

To program the larger EEPROM of the FT4232 you must specify
eeprom_type=0x56
in the configuration file of ftdi_eeprom.

As we cannot see what you are doing, perhaps you could post the content

Assuming my EEPROM is erased, I tried doing flash-eeprom.

this is indeed strange; that particular error message comes from
ftdi_usb_open_desc_index() in ftdi.c when your device was found by
libusb_get_device_list() but couldn't be opened by libusb_open()
immediately thereafter.

Assuming you didn't forget 'sudo' it looks like a problem with libusb,
outside the scope of libftdi.

Thank you, it seems the problem was sudo.
Now when I write I get:

FTDI eeprom generator v0.17
(c) Intra2net AG and the libftdi developers <***@intra2net.com>
FTDI read eeprom: 0
EEPROM size: -1
Used eeprom space: 230 bytes
FTDI write eeprom: 0
Writing to file: eeprom.new
FTDI close: 0

When I read I get:
FTDI eeprom generator v0.17
(c) Intra2net AG and the libftdi developers <***@intra2net.com>
FTDI read eeprom: 0
EEPROM size: 256
FTDI close: 0

That seems fine to me.
However after write I see no change in lsusb, I assume the serial number
should be changed, but I see no change so I have no idea if it did write or
not.
