If nothing happens, download the GitHub extension for Visual Studio and try again. SerialFlash provides low-latency, high performance access to SPI Flash memory with a filesystem-like interface for use with Arduino compatible boards.

Familiar file-based functions, similar to the SD library, are used to access data. In-progress file write and erase operations do NOT block read access on other files. SerialFlash automatically allocates files with Flash page and sector awareness, and supports suspending in-progress write and erase operations, to minimize read latency even while the Flash memory is "busy" writing data.

Performance oriented design does impose some usage limitations. Files are created with a fixed size which can never change or grow. Once created, files can not be renamed or deleted except for erasing the entire chip. Files begin with all bytes erased Each byte may be written only once.

Files created as erasable may be fully erased, to allow new data to be written. Best performance is achieved by writing in byte chunks, though individual bytes may be written. SerialFlash automatically detects SPI Flash chip type and capacity to automatically handle differences between supported chips.

Several limitations apply to writing.

Only previously unwritten portions of the file may be written. File sizes can never change. Writes may only be done within the file's original size. Only files created for erasing can be erased. The entire file is erased to all 0xFF bytes, which allows the file to be written with new data. New files must be created using these funtions.

Each returns true if the file is successfully created, or false if not enough space is available. Once created, files can never be renamed or deleted. The file's size can never change. Writing additional data can NOT grow the size of file. Files created for erasing automatically increase in size to the nearest number of erasable blocks, resulting in a file that may be 4K to K larger than requested.

The actual space used by the file is not reclaimed.

However, a new file with this name may be created after the original is deleted. A list of files stored in the Flash can be accessed with readdirwhich returns true for each file, or false to indicate no more files.

Any ideas how I can recover it? Note that both procedures seem to be executed well with blinking LEDs. Originally Posted by kaese. This happens on every bios version I use and is by far the safest and what it's currently on.

You mentioned that you bought a programmer. I also bought a programmer. EZP -- "E packet from China". The package was 3 weeks late and took nearly two months to arrive to my Southern California address. Also, be warned and use extreme caution Originally Posted by Nonny.

Digi-Key usually has them. I've seen them on ebay, usually vendors stuck with surplus or breaking their bulk orders into slim profits from individual orders.

You could try buying directly from Winbond, might be a waste of time but all the asking costs is an email. Last edited by Korth; at AM.Log in or Sign up. No risk as long as my solder skills and equipment are good enough. I have several new blank replacement chips, so I know the part numbers are correct. Chip is N25QA13 I choose the proper chip from the software list. The Revelprog does not verify the chip ID. I recently purchased a 48watt soldering tweezer with 5mm and 10mm tips.

This tool is the hands down winner for working with SOIC chips.

Currently working on CF 31's at the moment. Simple question. Are these chips interchangeable in a basic BIOS application? What are the differences in these chips?

ShawnNov 27, However, it depends on the flashing program the official, software-based one as to which eeproms are supported. The Winbond is a very common model, so that should have the least risk of being incompatible. Second thing to check is whether the hardware write-protect pin is default-off or default-on on the original eeprom; the system will have its pin 3 either powered to 3.

Those are rather behemoth-like chips, btw. Do they duplicate everything or is it a lot of empty space? Fascinating info. This is all just a learning experiment for me. I am working on an i3 unit of mine.

From the rom file loaded into the programmer, it looks like a lot of empty space. However on some oddball and customer specific units I have seen W25Q chips.
