changelog

基于ecos的redboot

	* src/net/tftp_client.c (tftp_stream_open): Don't try if no network.

2001-05-10  Gary Thomas  <[e-mail]>

	* cdl/redboot.cdl: Can't build RedBoot without virtual vectors.

2001-05-09  Mark Salter  <[e-mail]>

	* src/main.c (cyg_start): Cast CYGACC_CALL_IF_DELAY_US argument
	to a cyg_int32. Needed when sizeof(int) < sizeof(cyg_int32).

2001-05-07  Gary Thomas  <[e-mail]>

	* src/net/net_io.c (net_io_isr): Interrupt acknowledgement
	should rightly be done by the driver 'delivery' routine, not here.

2001-04-26  Gary Thomas  <[e-mail]>

	* src/main.c (do_caches): Display cache state if no arguments.

2001-04-13  Gary Thomas  <[e-mail]>

	* src/net/ping.c (do_ping): Tidy message.

2001-04-12  Robin Farine  <[e-mail]>
2001-04-12  Jonathan Larmour  <[e-mail]>

        * src/io.c (gets): Checks for buffer overflow and returns buflen
        if it reaches the end of the buffer.
	* src/main.c (cyg_start): Cope with gets() return being the
	buffer length.

2001-04-12  Mark Salter  <[e-mail]>
2001-04-12  Robin Farine  <[e-mail]>

	* src/net/enet.c (__eth_install_listener): Does not accept a
	handler for an eth_type less than 0x800.
	(__enet_poll): Only scan the handlers for a frame type greater
	than 0x800.

2001-04-09  Mark Salter  <[e-mail]>

	* src/printf.c (_vprintf): Fixed some portability problems where
	sizeof(int) != sizeof(long).

2001-04-09  Hugo Tyson	<[e-mail]>

	* src/main.c (do_cksum): Reduce warning absent posix_crc32().

	* src/main.c (cyg_start): Compare ram_end against workspace_end to
	see if there is *less* SDRAM than the MLT suggested, and shorten
	workspace et al accordingly.  This is needed if some SDRAM is
	"stolen" for use by eg. a PCI window, and mapped far away.

2001-04-03  Gary Thomas  <[e-mail]>

	* src/load.c (do_load): Fix 'raw' loading to check for valid
	base address _before_ trying to load anything.  Also, some
	reorg to make raw vs non-raw cleaner.

2001-04-02  Hugo Tyson  <[e-mail]>

	* src/flash.c (get_config): Update to support some new syntax:
	fco -l -n        ... lists showing nicknames instead of titles.
	fco -l -n -f     ... lists showing both nicknames and titles.
	fco nickname     ... goes straight to editing only nickname.
	fco nick value   ... sets nickname to value.
	All then follow the usual flow out, including the question
	Update RedBoot non-volatile configuration - are you sure (y/n)
	as it should be if you made a change.

2001-03-29  Mark Salter  <[e-mail]>

	* cdl/redboot.cdl (CYGSEM_REDBOOT_FIS_CRC_CHECK): New option to 
	enable (default) or disable CRC checks in FIS images.
	* src/flash.c: Use CYGSEM_REDBOOT_FIS_CRC_CHECK to decide whether
	to provide CRC for flash images.

2001-03-28  Mark Salter  <[e-mail]>

	* src/net/tcp.c (__tcp_handler): Don't send ACK from TIME_WAIT state
	unless the FIN comes in again.

2000-03-27  Grant Edwards <[e-mail]>

        * src/net/tcp.c (__tcp_handler): Fixed sequence number bug seen when
        doing an active close.

2001-03-23  Gary Thomas  <[e-mail]>

	* src/printf.c (_vprintf): Support %u (unsigned) descriptor.

	* src/main.c (do_cksum): New command to compute and print a POSIX
	checksum on a range of memory.

	* src/crc.c (posix_crc32): New routine - matches POSIX algorithm.

2001-03-21  Gary Thomas  <[e-mail]>

	* cdl/redboot.cdl: Back off previous change in number of packets.
	Also change minimum - below this, network debugging fails.

	* src/flash.c (fis_write): New function - support raw writes to FLASH.

	* src/net/enet.c (__enet_poll): Try to continue if out of packets.

	* src/main.c: 
	* src/load.c: 
	* src/flash.c: 
	* include/redboot.h: Keep track of available "user" RAM.

	* cdl/redboot.cdl: Reduce default number of [network] packets.

2001-03-20  Gary Thomas  <[e-mail]>

	* src/net/net_io.c (net_io_test): Change for new calling convention.

	* src/main.c (cyg_start): Idle processing now in I/O routines.

	* src/io.c (gets): Move idle processing into this function.

	* include/net/net.h (net_io_test): Needs idle parameter.

	* include/redboot.h: Change 'idle' functions to take state (idle/not).

2001-03-19  Jesper Skov  <[e-mail]>

	* cdl/redboot.cdl: Put version.o file in the public lib directory
	so other packages can get at it and link redboot.

2001-03-16  Gary Thomas  <[e-mail]>

	* src/flash.c (fis_create): Preserve memory [load/exec] address 
	when making assumptions [rewriting existing image].

2001-03-16  Mark Salter  <[e-mail]>

	* src/main.c (cyg_start): Restore console channel after returning
	from stub.

2001-03-15  Gary Thomas  <[e-mail]>
2001-03-15  Grant Edwards <[e-mail]>

	* src/net/bootp.c (bootp_handler): Guard against buffer overflow.

2001-03-15  Hugo Tyson  <[e-mail]>

	* src/flash.c (fis_create): The code was installing a default for
	img_size from data_length of an extant record.  That's zero, so,
	so whilst the flash was erased, no data was copied in!
	(fis_list): Added a -d to get the data length field displayed.

2001-03-15  Jesper Skov  <[e-mail]>

	* src/main.c: Make use of script variable conditional on flash.

	* include/redboot.h: Changed type of workspace_end to silence
	warning.

	* src/net/ping.c (do_ping): Fix warning.
	* src/net/pktbuf.c (__pktbuf_dump): Fix warnings.

2001-03-14  Gary Thomas  <[e-mail]>

	* src/main.c (do_go): Make timeout code consistent with other
	versions, e.g. script timeout.  Also, allow a script to continue
	if it was in effect when 'go' was called and ^C was typed.

	* src/flash.c (fis_create): Ask for additional user verification
	if any [important] parameters are being assumed [left out by user].
	This just adds a level of safety in the presence of assumptions.

2001-03-13  Gary Thomas  <[e-mail]>

	* src/main.c: Define 'workspace' based on MLT files, rather than
	simply using end of RAM area.

	* src/flash.c: Use 'workspace' for scratch area.

	* include/redboot.h: Define new variables 'workspace_XXX' to specify
	ares used by RedBoot for scratch, etc.

2001-03-12  Jesper Skov  <[e-mail]>

	* src/decompress.c: Removed Z_BAD_CRC hack. zlib does CRC checking
	now.

2001-03-09  Jesper Skov  <[e-mail]>

	* src/misc_funs.c: Added strncpy.
	* include/redboot.h: And declaration.

2001-03-08  Jesper Skov  <[e-mail]>

	* src/load.c (do_load): Added decompression support.
	* src/flash.c (fis_load): Same.

	* src/decompress.c: Added. Interfaces the zlib API.

	* include/redboot.h: Added some definitions used by decompression
	code.

	* cdl/redboot.cdl: Added option to control size of zlib bounce
	buffer.

2001-03-05  Jesper Skov  <[e-mail]>

	* src/main.c (cyg_start): Make sure communication channels are
	initialized.

2001-03-03  Gary Thomas  <[e-mail]>

	* src/main.c (do_idle): New function - all 'idle' handling is here.

	* src/io.c (mon_read_char_with_timeout): Improve timeout handling
	when scanning for a console by applying the minimum possible value
	(1 ms) to each channel, accumulating the total value.  The previous
	algorithm was quite poor on systems where there is no buffering,
	i.e. serial channels with no FIFOs, because each channel would 
	wait for T/N (t = total timeout, N = number channels).  This might
	possibly have been much longer than the devices could tolerate and
	still return valid data.

2001-03-01  Gary Thomas  <[e-mail]>

	* src/version.c: Add 'bootstrap' to banner so the world can see
	more of what RedBoot's all about.

2001-02-28  Gary Thomas  <[e-mail]>

	* include/redboot.h: Fix prioritization of 'init' table entries.

2001-02-26  Gary Thomas  <[e-mail]>

	* include/redboot.h (RedBoot_INIT_PRIO): Slight change - avoid
	arithmetic which C preprocessor doesn't handle anyway.  This also
	fixes prioritizing init entries.

	* src/flash.c (fis_load): Only load actual data [length] when loading
	an image.  

	* cdl/redboot.cdl: Change build rule to always rebuild 'version.o'
	whenever the application is relinked.  Thus the version string will
	always accurately reflect the actual build date/time.

2001-02-22  Hugo Tyson  <[e-mail]>

	* cdl/redboot.cdl: New config options to control default creation
	of various FIS image files.  Also opt for a reserved area at the
	base of flash, eg. for user's POST or other pre-RedBoot code that
	we must not interfere with.  This isn't the same as the extant
	boot_offset option, so the two are made to work together.
	Likewise an offset for the start of a POST-cooperative RedBoot
	image, if any; the value is of course platform dependent, not
	simply after the first RedBoot image, if there is one.

	Clarification: a POST-cooperative RedBoot image is a ROM-start
	image that runs at a higher address in ROM, and which omits some
	of the hardware initialization because it's already done by
	whatever came before.  Most targets do not have such a thing;
	those that do, it is created by a config export file, not by a new
	startup type.  A POST Redboot can be tested from a plain ROM
	redboot by just calling its entrypoint once it is installed in
	flash; eg. by "go 0x50040044" at the RedBoot prompt.

	* src/flash.c (fis_init): Create additional optional entries for
	  o (reserved) reserved area at start, for preboot or post code.
	  o RedBoot itself now optional
	  o RedBoot[post]
	  o RedBoot[backup]
	Also initialize their addresses, sizes, accordingly.
	The default behaviour is unchanged.
	The flash erase is moved to after the fis table init because the
	fis table init most conveniently calculates the high water mark of
	built-in default objects.
	(fis_create): If creating a file which already exists (most likely
	one of the preconfigured defaults) pick up Flash address and
	length (the two required parameters) from there.  They're required
	to be the same to it's no loss of generality, and saves typing,
	makes the default entries far more useful and so on.
	(fis_delete): Skip those entries which were
	preconfigured; we want nobody to be able to delete these.
	(fis_free): Start searching for free space to list only after the
	reserved base area - if there is one.
	(fis_find_free): Start searching for free space only after the
	reserved base area...

2001-02-22  Jesper Skov  <[e-mail]>

	* src/flash.c: Added default case to switch statement.

2001-02-20  Gary Thomas  <[e-mail]>

	* src/load.c: Remove unnecessary \r from usage message.

	* src/printf.c (_vprintf): Ensure CR/LF sequence, not LFCR.

	* src/net/ping.c: 
	* src/flash.c: Better usage messages [no naked linefeeds].

	packet lengths.

	* src/load.c: Tidy up usage message.

2001-02-16  Nick Garnett  <[e-mail]>

	* src/flash.c (load_flash_config): Move setting of config_ok to
	true to before we look for a script to run. Otherwise scripts just
	don't work.

2001-02-14  Hugo Tyson  <[e-mail]>

	* src/load.c (do_load): Wrap the help message at < 80 cols and fix
	a coupla warnings.

2001-02-13  Hugo Tyson  <[e-mail]>

	* src/flash.c: Fix token/string pasting thinko: ## operators are
	not needed and do confuse some compilers.

2001-02-12  Jesper Skov  <[e-mail]>

	* src/main.c: Use CYGNUM_HAL_VIRTUAL_VECTOR_DEBUG_CHANNEL instead
	of CYGNUM_HAL_VIRTUAL_VECTOR_CONSOLE_CHANNEL.

2001-02-11  Gary Thomas  <[e-mail]>

	* src/net/ping.c (do_ping): Accomodate new MS_TICKS scheme.

2001-02-09  Grant Edwards  <[e-mail]>

	* include/net/net.h (MS_TICKS_DELAY): New macro, different from
	MS_TICKS() so that MS_TICKS() gets the current tick count, and
	MS_TICKS_DELAY is used in a delay loop to actually do a delay.

	* src/ticks.c (get_ms_ticks): New function imlementing rework of
	MS_TICKS

	* src/net/net_io.c (net_io_getc): Use MS_TICKS_DELAY() instead of
	CYGACC_CALL_IF_DELAY_US() directly
	(net_io_getc_timeout): Likewise

	* src/net/udp.c (__udp_recvfrom): MS_TICKS -> MS_TICKS_DELAY
	* src/net/bootp.c (__bootp_find_local_ip): Likewise

2001-01-31  Grant Edwards <[e-mail]>

	* src/net/net_io.c (net_io_test): Use new idle function to
	poll for incoming network connections.  Removes #if requirements
	from the main CLI loop.

	* src/main.c (cyg_start): 
	* include/redboot.h (RedBoot_idle): Add new tables to support
	user defined functions to be called when idle (during command input).

2001-01-31  Gary Thomas  <[e-mail]>

	* include/redboot.h: 
	* src/main.c (cyg_start):
