Question on programming of Intel 82574 external flash with eeprom access tool

Hi,

 

I have an existing card having a WS82574 Ethernet chip with an obsolete SPI Flash ATMLH726 as its NVM.

I dumped the image of the flash with the EEPROMAccessTool with the following command :

 

sudo ./EepromAccessTool -dump -NIC=1

 

The dumped image file is 32kbit and has MAC address at the start address.

Then I replaced the ATMLH726 with a Microchip SST25VF010A 1Mbit SPI flash and tried to write the dumped image file back to  the blank SST25VF010A flash with the command :

 

sudo ./EepromAccessTool -NIC=1 -f=filename.otp

 

. Thereafter I execute command

 

sudo ./EepromAccessTool -dump -NIC=1

 

to check if the programming is successfully. The return dump image file has all 0XFF as its content, indicating the content is still empty and the programming is not successful.

 

Please forward this email to relevant party to advise the cause of failure.

 

Best Regards,

Lim Hui Peng
