SPI flash and EEPROM dump of the ODI DFP-34x-2c2

[lehoangnb]

Its for ODI DFP-34x-2c2 with 8MB MX25L6433F flash and 24C04 EEPROM

SPI Flash info

• Flash name: MX25L6433F SPI 8MB
• File name: ODI_DFP-34X-2C2_factory_8M_v220923.bin
• sha256: 5e3572c2c6821b8f345d6564ae547aaf734b227c678744b276d311cb97006cd7
• Both layout is running 220923 @Anime4000 modified firmware

EEPROM info

• EEPROM name: 24C04 4K (512B) I2C (SOT23 package)
• File name: ODI_DFP-34X-2C2_eeprom_4K.bin
• sha256: 6342c4bdefee80e1ca238615c3840184eaec5cdae48dc403111bb5b09f96fef0

Notice

• Use only 3.3V level for both Flash and EEPROM
• In most case, flashing eeprom is not necessary

Besides, eeprom need to be modified to switch to 2500basex mode for host device.

Hi. Do you have the original .bin of the ODI? I lost access to the IP interface, and i dont wat to do UART as i have a RT809H programmer. Will flash direct the .bin with aligator clip. I will restore original firmware and then change to M114_sfp_ODI_PPPOE_210702 firmware because they do PPPoE auth. Do your firmware do PPPoE Auth ? I have a Chinese Switch Layer 3 and i am having a lot of probleming with low speed only using my switch L3. Maybe my switch have a problem with HiSGMII PHY, HiSGMII MAC and 2500Base-X? I lost access when i changed to LAN_SDS_MODE 6. As i did no know about your work, i bought the version DFP-34G-2C2 instead of DFP-34X-2C2. But as i checked in the repo, the newer version like mine come with realtek chip, maybe RTL9602(i lost access now but i checked in past in /proc/cpuinfo). So i am using always the X version of firmware. Do you know if i will loose anything using the G version? (mine using realtek chip too)

The problem is my config has a flash set SDS that I lost access in IP interface. When you flash the firmware they preserve this config, so I still without access. But I done UART and switched backed SDS and recovery IP access.

lost entire night trying to do UART, and the morning I checked I lost one capacitor and two resistor 🤦‍♂️. As I have two units I checked the capacitors nF in other board and I am doing reverse engineering to find in one of my iPhone donate boards one capacitor and two resistors with same value. Already found the capacitor, just need to find resistor 🙏

Pull out and plug in fiber 5 times in 30 seconds would reset everything(except loid stuff)

[duskyzaoKING]

I didn’t know. But this erase SDS value too? The parameter to get 2.5GB

[Headcrabed]

My stock firmware has a option to change speed mode in web interface, and it works when that blocked me out.

Trying to Finding this two micro resistors 😂😂

@Anime4000 i flashed you BIN but they didn’t come with your interface customization. Maybe is it in the eprom? I only flashed the SPI

[Anime4000]

@lehoangnb I have question,
My stick using different brand SPI Flash, something off-brand called CFEON.
It should be similar to MXIC MX25L6433F right?

[duskyzaoKING]

You can check in datasheet of the two SPI Flash. But i can confirm its compatible, because i flashed your .bin and mine SPI its MXIC and worked ok. The bin didnt come with your logo customization, but came with your OMCI info and other things

[Anime4000]

the GUI Customization not yet public 😅 just to make sure no issue or glitch

[lehoangnb]

Maybe similar if both have same size, (but be aware, kernel in firmware must have driver for SPI flash)

[Anime4000]

Alright, just to be safe, read multiple time, backup multiple time, compare and verify multiple time, I'll get back once required tool arrive

I let everyone know,
STICK3V08 do not have 24C04F EEPROM thus cannot change SFP I2C

but I found C2 Debugger pads

I tried program SFP I2C 0x50 via CH341a I2C,...
with V06 stick, you can do that, but not V08 stick, some what have write protect...
