EEPROM programming issue

[ar0mat]

Hello! I'm trying to program the EEPROM. I have been stuck in this step.

$ sudo python3 ovctl.py -p ov3.fwpkg eep-program 10000
FPGA not loaded, forcing reload
FPGA: Bitstream timestamp 2014/11/10 16:31:07
FPGA: sending configuration bitstream
FPGA: CRC OK
FPGA: configured
00: ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff 
10: ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff 
20: ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff 
30: ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff(ffff)
EEPROM: Device blank or checksum incorrect
EEPROM: Generated serial OV010000

After the assembly process, I noticed that EEPROM had been soldered other way around. I have that chip replaced by a new one, but it still does not work.

FTDI and Y2 oscillator are soldered correctly.

When I'm doing the report, I obtain the following communicate:

$ sudo python3 ovctl.py -p ov3.fwpkg report
EEPROM: Device blank or checksum incorrect

Please run this tool with the subcommand 'eep-program <serial number>'
to program your EEPROM. The FT2232H FIFO will not work correctly with
default settings.

I've tried to erase the number and program it once again, but I received a message as on the top.

What does eep-program say after you fixed the EEPROM? Does it complain or do you get a successful EEPROM: Programmed message?

If programming fails then you might still have a hardware issue. Check for short and open pins. Also note that you will probably have to unplug and plug in the OV after programming the EEPROM, to make sure it loads the new config.

Here is what I receive after fixing the EEPROM:

$ sudo python3 ovctl.py -p ov3.fwpkg eep-program 1421312
00: ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff
10: ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff
20: ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff
30: ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff(ffff)
EEPROM: Device blank or checksum incorrect
EEPROM: Generated serial OV142131

Basically, nothing has changed. Unplugging hasn't solved the problem. I've checked the connections. There is no fault in assembly. When I enumerate devices with lsusb command, I receive

$ lsusb
Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 005: ID 046d:c31c Logitech, Inc. Keyboard K120
Bus 001 Device 004: ID 046d:c077 Logitech, Inc. M105 Optical Mouse
Bus 001 Device 011: ID 0403:6010 Future Technology Devices International, Ltd FT2232C Dual USB-UART/FIFO IC
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

so FT2232H is recognizable.

I'm curious what are these lines responsible for:

00: ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff
10: ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff
20: ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff
30: ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff(ffff)

For now, I am not able to do any test. I tried to test an SDRAM, but I get failures only.

$ sudo python3 ovctl.py -p ov3.fwpkg sdramtest
FPGA not loaded, forcing reload
FPGA: Bitstream timestamp 2018/11/19 13:37:13
FPGA: sending configuration bitstream
FPGA: CRC OK

EEPROM: Device blank or checksum incorrect

Please run this tool with the subcommand 'eep-program <serial number>'
to program your EEPROM. The FT2232H FIFO will not work correctly with
default settings.

As mentioned above, reprogramming doesn't help. I'm considering replacement of the FT2232H IC.

When reprogramming EEPROM, I receive information like that:

$ sudo python3 ovctl.py -p ov3.fwpkg eep-erase
00: ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff
10: ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff
20: ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff
30: ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff ffff(ffff)
EEPROM: Device blank or checksum incorrect
EEPROM: Erased

$ sudo python3 ovctl.py -p ov3.fwpkg eep-program 2227855

If you don't get an "EEPROM: Programmed" message on eep-program then programming is failing. Check your FTDI and EEPROM pins for shorts and opens. If the EEPROM has been replaced then maybe something on the FTDI is broken, though honestly I would be surprised if placing the EEPROM on backwards would damage the FTDI. Make sure you have the right part number for the EEPROM too. Apparently there are variants with a different pinout.

Nothing will work without the EEPROM present and programmed, unfortunately. This is a limitation of how the FTDI works. The FPGA can be configured without an EEPROM, but I/O will not work.

I have the FT2232H chip in my OpenVizsla replaced. Now, everything worsk excellent. Thank you for you help and time.
