I v got some new modems to play with and i want to dump the firmware ( doh )
I looked on the forum but cant find my anwser
Can somebody create/share/help/edit a XML file for my usbjtag + EPC3928
The EPC3928 is a broadcom powerd modem with a spi flash , 5ghz and 2.4 ghz network running side by side. in my opinion a pretty cool modem .
Olso is there a serial port onboard?
Anny help is welcome , i made olso some pics of inside the modem.
This is another modem with FL256 flash. Tell me if you can read/write this flash or there might be a need to release a newer version to support this flash.
I have ordered FL256 flash from digi-key and will see if there is a need to add additional code to support this chip.
The chip should arrive this week and if you see a new version released then most likely it is to support flash that is larger than 16M.

I didnt check it out yet usbbdm , kuz i thought i need a xml to proper rw
Thx alot for yout time.
To read the entire flash is not an issue. However to erase and program needs a little bit of work. This flash does not use uniform sector size. I need to adjust the code to work with this chip.

No rush man , already thankfull for the great support .
Download 0.71. There is a xml called fl256 for development.
IF you use it for another device make sure you have this line in your xml.
<SPIFlash>1</SPIFlash>
This is using algorithm for larger than 16M SPI flash. (4 bytes address mode).
Could you finish the xml for this modem ? i have a full dump here from my isp
I just dont have the skills to use the adresses where firmwares start or end
