ERASE addr [increment count] [mode [wait]]

The flash memory may be individually erased or unlocked via the Telnet interface. In order to make erasing of multiple flash sectors easier, you can enter an erase list. All entries in the erase list will be processed if you enter ERASE at the Telnet prompt without any parameter. This list is also used if you enter UNLOCK at the Telnet without any parameters. With the "in- crement" and "count" option you can erase multiple equal sized sectors with one entry in the erase list.

address	Address of the flash sector, block or chip to erase
increment	If present, the address offset to the next flash sector
count	If present, the number of equal sized sectors to erase
mode	BLOCK, CHIP, UNLOCK
	Without this optional parameter, the BDI executes a sec-
	tor erase. If supported by the chip, you can also specify
	a block or chip erase. If UNLOCK is defined, this entry is
	also part of the unlock list. This unlock list is processed
	if the Telnet UNLOCK command is entered without any
	parameters.
wait	The wait time in ms is only used for the unlock mode. Af-
	ter starting the flash unlock, the BDI waits until it pro-
	cesses the next entry.
Example:	ERASE 0xff040000 ;erase sector 4 of flash
	ERASE 0xff060000 ;erase sector 6 of flash
	ERASE 0xff000000 CHIP ;erase whole chip(s)
	ERASE 0xff010000 UNLOCK 100 ;unlock, wait 100ms
	ERASE 0xff000000 0x10000 7 ; erase 7 sectors

Example for the ARM PID7T board (AM29F010 in U12):

[FLASH]
WORKSPACE	0x00000000	;Workspace in target RAM for faster programming algorithm
CHIPTYPE	AM29F	;Flash type
CHIPSIZE	0x20000	;The size of one flash chip in bytes
BUSWIDTH	8	;The width of the flash memory bus in bits (8 16 32)
FILE	C:\gdb\pid7t\bootrom.hex		;The file to program
ERASE	0x04000000	;erase sector	0	of flash SIMM
ERASE	0x04004000	;erase sector	1	of flash SIMM
ERASE	0x04008000	;erase sector	2	of flash SIMM
ERASE	0x0400C000	;erase sector	3	of flash SIMM
ERASE	0x04010000	;erase sector	4	of flash SIMM
ERASE	0x04014000	;erase sector	5	of flash SIMM
ERASE	0x04018000	;erase sector	6	of flash SIMM
ERASE	0x0401C000	;erase sector	7	of flash SIMM

the above erase list maybe replaced with:

ERASE 0x04000000 0x4000 8 ;erase 8 sectors
