3.2.4 Part [FLASH]

The Telnet interface supports programming and erasing of ﬂash memories. The bdiGDB system has to know which type of ﬂash is used, how the chip(s) are connected to the CPU and which sectors to erase in case the ERASE command is entered without any parameter.

CHIPTYPE type	This parameter deﬁnes the type of ﬂash used. It is used to select the cor-
	rect programming algorithm.
	format	AM29F, AM29BX8, AM29BX16, I28BX8, I28BX16,
		AT49, AT49X8, AT49X16, STRATAX8, STRATAX16,
		MIRROR, MIRRORX8, MIRRORX16,
		M58X32, AM29DX16, AM29DX32
	Example:	CHIPTYPE AM29F
CHIPSIZE size	The size of one ﬂash chip in bytes (e.g. AM29F010 = 0x20000). This value
	is used to calculate the starting address of the current ﬂash memory bank.
	size	the size of one ﬂash chip in bytes
	Example:	CHIPSIZE		0x80000
BUSWIDTH width	Enter the width of the memory bus that leads to the ﬂash chips. Do not en-
	ter the width of the ﬂash chip itself. The parameter CHIPTYPE carries the
	information about the number of data lines connected to one ﬂash chip.
	For example, enter 16 if you are using two AM29F010 to build a 16bit ﬂash
	memory bank.
	with	the width of the ﬂash memory bus in bits (8 16 32)
	Example:	BUSWIDTH		16
FILE ﬁlename	The default name of the ﬁle that is programmed into ﬂash using the Telnet
	’prog’ command. This name is used to access the ﬁle via TFTP. If the ﬁle-
	name starts with a $, this $ is replace with the path of the conﬁguration ﬁle
	name. This name may be overridden interactively at the Telnet interface.
	ﬁlename	the ﬁlename including the full path or $ for relative path.
	Example:	FILE	F:\gnu\arm\bootrom.hex
		FILE	$bootrom.hex
FORMAT format [offset]	The format of the ﬁle and an optional address offset. The optional param-
	eter "offset" is added to any load address read from the program ﬁle.
	format	SREC, BIN, AOUT, ELF or COFF
	Example:	FORMAT SREC
		FORMAT ELF 0x10000
WORKSPACE address	If a workspace is deﬁned, the BDI uses a faster programming algorithm
	that runs out of RAM on the target system. Otherwise, the algorithm is pro-
	cessed within the BDI.The workspace is used for a 1kByte data buffer and
	to store the algorithm code. There must be at least 2kBytes of RAM avail-
	able for this purpose.
	address	the address of the RAM area
	Example:	WORKSPACE 0x00000000
