E680

From OpenEZX

Summary Product name: E680 Codename: - Generation: 1st (Blue bootloader screen) Project device: Yes Device support: Working communication with BP Motorola source code: https://opensource.motorola.com/sf/projects/a780e680 PCB pictures: E680 Board The E680 is from a hard- and software point very similar to the A780, although there are some differences. It doesn't have a flip and you have a SD card slot instead a microSD. The E680 is only known to be sold in Asia. The differents revisions, the E680i and E680g are pretty much the same as the E680. The "g" stands for more preinstalled games.

Flash Memory

See also Internal Flash: this is a Gen 1 EZX phone, and all of those have the same flash chips.

Here is a map of the flash memory of an E680i:

ROFLASH Driver status: Ready
ROFLASH area name is rootfs
ROFLASH area size = 26083328 bytes
ROFLASH area offset = 1179648 bytes
ROFLASH area l_x_b(10)
ROFLASH area name is NO-USE
ROFLASH area size = 0 bytes
ROFLASH area offset = 27262976 bytes
ROFLASH area l_x_b(1000)
ROFLASH area name is setup
ROFLASH area size = 131072 bytes
ROFLASH area offset = 33161216 bytes
ROFLASH area l_x_b(1000)

And the partitions as they are used by original E680i Motorola firmware:

Note that NAND flash is not accessible to OpenEZX kernels.
