Hi everyone , i have here an old modem that i am trying to flash a new Firmware over SPI .
the chip is an Cfeon EN25Q128
But the identification i get from this chip its : RDID:0x1C3018 REMS:0x1C17
the total flash size is 16Mbytes
In the datasheet of the chip i can see this data :
Block 0 to 254 000000h-FEFFFFh 16320KB Lower 255/256
But i have no idea how to convert it in a multiple of megabyte for blackcat understands it .
I was looking at SPI mode configuration :
and what i think that one of my problems is , is that i am unable to write in chip size (blackcat) the proper information for the program to write the full firmware :
I am unable to try the automatic mode in SPI because blackcat is detecting an unknown chip :
But this chip is already in Blackcat detection :
A picture of the modem i am trying to flash a new firmware :
(the raspberry device is just providing an extra 3,3V to the chip in order for me to be able to read it without turning the modem on)
Any help on this is very appreciated .
Thank you and sorry for the long thread , i wanted to post as much information as i could to be more easier to understand .
