Re: [flashrom] Flashing iPXE on Intel i210 on Supermicro X11SSL-F

Thanks Alex and I've tried BootUtil - but no luck. I've read the discription of BootUtil thanks to your link and found an important article: " * BootUtil is not intended as a utility for LAN-On-Motherboard (LOM) implementations. Adjustments made to BootROM settings on LOM implementations may not affect how the adapter operates. " And well this nic which i was trying to flash is a LOM. So i guess there will be no chance to flash it.

You have to be much more specific with your question, otherwise the answer is simply: the source code explains everything in detail. Nico

Hello, I am interested in figuring out how flashrom writes to the flash, and where I can find resources to write my own version of flashrom. Sincerely, Matthew

How and if it will work, depends on many things: 1. is the board designed for ISP; if, follow the manual; if not 2. how do you power the flash chip? through the board's regular power supply (strongly advised)? or through the ch341a (discouraged unless you know exactly what you are doing)? 3. are all input pins of the flash chip in a defined state? (e.g. don't forget /HOLD and /WP). See also [1] and [2]. > The EEPRom I'm trying to write is > S25FL128SAGMFI000. Regarding ISP, the board the chip is soldered to matters more than the chip. What board is it? Hope that helps, Nico [1] https://flashrom.org/ISP [2] https://flashrom.org/Common_problems

Some troubles connecting a W25X40ALSNIG flash chip to raspberry pi (v3 model B)
by Jesse Li 06 Mar '18

06 Mar '18

Hey, I'm trying to read from and flash to a W25X40ALSNIG [0] that's still mounted to its hard drive PCB. Following the table from the raspberry pi wiki page [1], and assuming the raspberry pi pin numbers it mentions are physical pin numbers (and not the pi's strange GPIO numbering scheme) I connected the legs of the flash chip to the raspberry pi's GPIO pins. However, when the two are attached, the pi won't boot (it'll show the three raspberries in the corner, then it shuts off). I've isolated this to the VCC (connected to header 17, 3v3) and GND (connected to header 25, GND) , where having all of the legs of the flash chip detached from the pi except for those two will reproduce my problem (I hope testing that didn't actually kill the chip). What am I missing? [0] http://www.alldatasheet.com/datasheet-pdf/pdf/235125/WINBOND/W25X40ALSNIG.h… [1] https://www.flashrom.org/RaspberryPi

Hi I need help with flashrom . I'm unable to write a firmware using CH341A programmer, test clip pomona 5252 .The EEPRom I'm trying to write is S25FL128SAGMFI000. You can find output attached Thanks Luca
