problem witch seagate bios chip (Sanyo 25FS406)

[mov45]

Hi I am trying to download bios from chip (Sanyo 25FS406), my soft is XGPRO and the chip is no on the list of that program, somebody know is there a simillar chip on the list wchich i can make a download a bios?

Just select a 1.8V 4Mbit SPI flash chip with the same pinout:

Few days looking but i can not find (take a hit) similar chip to this one, if somebody know what to select in XGPRO please help

[fzabkar]

Maybe your programmer cannot handle 1.8V chips?

In the following example you need the TL866II Plus version:

My have 1.8v it is XGecu TL866II Plus, but I can't find simmilar chip in the soft

There's nothing special with 25FS406 as long as reading is concerned, you could select any chip with same capacity and supply voltage.

I try so many chips and wan't work, please tell me for exmaple what chip to choice in your opinion?

W25Q40EW (Winbond)

All the time is info "ID Error! Check the chip correctly? whether contact good pin?"

[fzabkar]

Doesn't your software allow you to forcibly select a particular chip? Is there some kind of configuration file that defines the parameters of the supported ICs?

[pepe]

Does the sw tell you what ID it read from the chip?

Thanks guys for ansewer, thats look like on soft:

an ID of 00 00 00 00 is not what you would want. 25FS406 should have ID 0x62, 0x16, 0x13 so either the chip is toast or your soldering is bad.

Hi,
It all depends on whether the programmer checks the MID ID or JEDEC ID

(LE25U40. MID:0x00000000 JEDEC:0x00130662)

If you mean cmd 0xAB, it gives nonzero data after 3 dummy bytes and the programmer sw should know that coz it is the same in 25Q40, so i doubt this is the problem.

At this point I would test the method with a known good chip.

90h MID ID
9Fh JEDEC ID

The LE25FS406 only supports 9Fh, and therefore the 90h response is all zeros

yeah, indeed. But cmd 90 responds with 2 bytes (on 25Q40), while there are 3 00s the util shows, which better corresponds to the response of 9F.
So i would definitely test the setup with a known good chip to clear up these things.
