- Subject: [ECOS] 2 types of FLASH memory
Hello,
Is it possible, with eCcos, to have a FLASH file system that covers 2
different FLASH banks?
I have a board that has 2 different banks of FLASH memory.
One consists in 2 AM20LV040B organized as a 16 bit memory:
- CYGNUM_FLASH_INTERLEAVE = 2
- CYGNUM_FLASH_WIDTH = 8
- CYGNUM_FLASH_SERIES = 1
The 2nd one consists of 4 AM29LV116D) organized as a 32 bit memory:
- CYGNUM_FLASH_INTERLEAVE = 2
- CYGNUM_FLASH_WIDTH = 16
- CYGNUM_FLASH_SERIES = 2
The design idea was to have the possibility to change the program (stored in
the small 2*AM29LV040B which has a socket), and store a large database in the
other FLASH bank.
Thank you for your answer,
Radu Cernea
