(copy target memory)

This is a dedicated command for the flash writer of the S5U1C17001H.

It loads the data stored in target board memory into the S5U1C17001H so that the data can be written to flash

c17 fwdc SourceAddr Size EraseStartBlock EraseEndBlock EraseParam [ Comment ]

Target memory address from which to copy (flash on the CPU side, in decimal, hexadecimal,

Number of bytes to copy (decimal or hexadecimal)

EraseStartBlock: Block at which to start erasing (flash on the CPU side, in decimal or hexadecimal)

EraseEndBlock: Block at which to complete erasing (flash on the CPU side, in decimal or hexadecimal)

Erase parameter

A parameter passed to the erase routine in an external routine call

Comments to identify data/address information (may be omitted)

0 ≤ SourceAddr ≤ 0xfffffe (A0 = 0), 0 ≤ Size ≤ 0xfffffe (D0 = 0),

0 ≤ EraseStartBlock ≤ 0xffffffff, 0 ≤ EraseEndBlock ≤ 0xffffffff

When EraseStartBlock = EraseEndBlock = 0, all blocks in flash memory are assumed to be

0 ≤ comment size ≤ 128 bytes

Usage example

(gdb) c17 fwdc FLASH_START 0x100000 0 0 0x200000

The range of flash memory to be erased (all blocks in flash memory) is set, and 1MB of area is copied from

FLASH_START in target memory to the S5U1C17001H.

• This command cannot be used in simulator mode.

• This command can be used with the ICD Mini (S5U1C17001H). It cannot be executed normally with the

ICD board (an error message will not be displayed).

• The ICDmini flash memory can retain up to 4 MB of data.
