The flash commands affect the StrataFlash devices on the ATCA-9305 circuit board. There 
are four flash banks on the ATCA-9305 board (see “Flash” on page 4-7). They can be 
accessed by: 

• the individual bank (1, 2, 3 or 4), or

• the address, where both banks are regarded as one contiguous address space

The following flash commands access the individual flash bank as flash bank 1. To access the 
individual sectors within each flash bank, the sector numbers start at 0 and end at one less 
than the total number of sectors in the bank. For a flash bank with 128 sectors, the follow-
ing flash commands access the individual sectors as 0 through 127.

The cp command can be used to copy data into the flash device. For the cp command syn-
tax, refer to “Memory Commands” on page 9-11.

The erase command erases the specified area of flash memory.

Erase all of the sectors in the address range from start to end.

erase start end

Erase all of the sectors SF (first sector) to SL (last sector) in flash bank # N.

erase N:SF[-SL]

Erase all of the sectors in flash bank # N.

erase bank N

Erase all of the sectors in all of the flash banks.

erase all

The flinfo command prints out the flash device’s manufacturer, part number, size, number 
of sectors, and starting address of each sector.
