Correct an instruction + specification (cut&paste error). + +2001-11-21 Brian S. Dean <bsd@bsdhome.com> + + * avr.c, config_gram.y, lexer.l, term.c: + In interactive mode, reset the address and length if we start dumping + a memory type different than the previous one. + + * avr.c, avrdude.conf.sample, config_gram.y: + Allow instruction data to be specified more flexibly, which can be + used to make the instruction input more readable in the config file. + + * main.c: Bump version number. + + * Makefile, avr.c, avr.h, avrdude.conf.sample, config.c, config.h: + * config_gram.y, fileio.c, fileio.h, lexer.l, main.c, term.c: + This is a major re-write of the programming algorithms. The Atmel + serial programming instructions are not very orthoganal, i.e., the + "read fuse bits" instruction on an ATMega103 is an entirely different + opcode and data format from the _same_ instruction for an ATMega163! + Thus, it becomes impossible to have a single instruction encoding + (varying the data) across the chip lines. + + This set of changes allows and requires instruction encodings to be + defined on a per-part basis within the configuration file. Hopefully + I've defined the encoding scheme in a general enough way so it is + useful in describing the instruction formats for yet-to-be invented + Atmel chips. I've tried hard to make it match very closely with the + specification in Atmel's data sheets for their parts. It's a little + more verbose than what I initially hoped for, but I've tried to keep + it as concise as I could, while still remaining reasonably flexible. + +2001-11-19 Brian S. Dean <bsd@bsdhome.com> + + * avr.c, avr.h, avrdude.conf.sample, main.c, ppi.c, term.c: + Add support for ATMega163. + + Add support for reading/writing ATMega163 lock and fuse bits. + Unfortunately, in looking at the specs for other ATMega parts, they + use entirely different instruction formats for these commands. Thus, + these routines won't work for the ATMega103, for example. + + Add support for sending raw command bytes via the interactive terminal + interface. This allows one to execute any programming instruction on + the target device, whether or not avrprog supports it explicitly or + not. Thus, one can use this feature to program fuse / lock bits, or + access any other feature of a current or future device that avrprog + does not know how to do. + + Add in comments, an experimental instruction format in the + configuration file. If this works out, it would allow supporting new + parts and non-orthoganal instructions across existing parts without + making avrprog code changes. + +2001-11-17 Brian S.

Dean <bsd@bsdhome.com> + + * main.c: Version 1.1 + + * main.c: + Hmmm ... cvs co -D <timestamp> does not work. Change the revision + timestamp to a full date/time value. + + * avr.c, fileio.c, main.c, ppi.c, term.c: + Add a -V option to display the version information about each + component module. This is intended for support purposes, so that I + can tell unambiguously what version a binary out in the field is. + + Additionally, display a revision timestamp along with the version + number. This also is intended for aiding in support and is the Unix + time of the latest component module. Having this, should allow me to + do a "cvs co -D timestamp avrprog" and get exactly the source of the + version that is being reported. + + * fileio.c: + Return the maximum address (+1) written as opposed to the actual + number of bytes written. The presence of an Intel Hex address + record can cause these two number to be different; but the callers + of this routine need the former. + + * main.c: + Fix a place where we were exiting without applying the exit-specs. + + Wrap a long line. + + * avr.c, fileio.c: avr.c: Update a comment. + + fileio.c: Properly handle all the Intel Hex record types that I can + find information about. + +2001-01-25 Brian S. Dean <bsd@bsdhome.com> + + * Usage, avr.h: Get rid of the Usage file. + +2001-01-24 Brian S. Dean <bsd@bsdhome.com> + + * Makefile, avr.c, avr.h, main.c, pindefs.h, ppi.c: + Move pin definitions to their own file. + + First pass at providing feedback via the optionally connected leds. I + don't actually have any of these attached to my programmer, so I can + only guess as whether this is toggling them on and off correctly. + + Also, enable and disable the optional 74367 buffer. + + * avr.h, main.c, ppi.c, ppi.h, avr.c: + Rearrange the pinout for the programmer to be a little more logical. + Provide hooks to support a buffered programmer, pin 6 is now used to + enable a buffer that can be used to isolate the target system from the + parallel port pins. This is important when programming the target + in-system. + + Totally change the way the pin definitions are defined. Actually + set/clear pins based on the way more intuitive pin number, instead of + PPI data register, bit number combination. A table of pin data is + used so that any hardware inversion done by the parallel port is + accounted for, what you set is actually what appears at the pin. + Retain the old method for handling Vcc, however, because the hold + method is much easier to use when setting / retrieving multiple pins + simultaneously. + +2001-01-22 Brian S. Dean <bsd@bsdhome.com> + + * Makefile: Don't gzip the man page. + + * avrdude.1: .Nm macro fix. Submitted by Joerg. + + * main.c: Cosmetic, don't output a preceding linefeed for usage(). + + * Makefile, avr.c, avr.h, fileio.c, term.c: + Makefile : use gzip -f for man page installation so that we don't get + prompted. + + avr.c avr.h fileio.c term.c : + + Change the avrpart data structure so that the typedef AVRMEM is + used as an index into an array for the sizes of the memory types + and also for pointers to buffers that represent the chip data for + that memory type. This removes a lot of conditional code of the + form: + + switch (memtype) { + case AVR_FLASH : + ... + } + + Also, re-code avr_read_byte() and avr_write_byte() to properly + handle the flash memory type without having to tell them whether + they should program the high byte or the low byte - figure that + out from the address itself. For flash memory type, these + routines now take the actual byte address instead of the word + address. This _greatly_ simplifies many otherwise simple + operations, such a reading or writing a range of memory, by not + having to worry about whether the address starts on an odd byte + or an even byte. + +2001-01-20 Brian S. Dean <bsd@bsdhome.com> + + * avr.c, avr.h, fileio.c, fileio.h, main.c: + Return error codes instead of exiting, thus making sure that we exit + only via main() so that the exitspecs are properly applied. + + When reading input data from a file, remember how many bytes were read + and write and verify only that many bytes. + + Don't complain when an input file size is smaller than the memory size + we are programming. This is normal. + + * fileio.c: + Correct checksum calculation; failure to account for the value of the + record type was causing non-zero record types to be calculated + incorrectly. + + * Makefile, main.c: Makefile : install the man page + + main.c : drop the giant usage text now that we have a man page. + + * avrdude.1: + Add initial man page graciously contributed by Joerg Wunsch. Thanks + Joerg! + +2001-01-19 Brian S. Dean <bsd@bsdhome.com> + + * term.c: + Accept abbreviations for eeprom and flash for the dump and write + commands. + + Fix small bug keeping 1 character command lines from being added to + the history. + + * term.c: + Implement enough state in cmd_dump so that if it is called with no + arguments, it successively dumps the next chunk of data of the same + previously specified length. + + * term.c, term.h, fileio.c, fileio.h, main.c, ppi.c, ppi.h: + * Makefile, avr.c, avr.h, avrprog.c: + The program was getting too large for a single file. Split it up into + more modular pieces. + + Also, accept command abbreviations as long as they are not ambiguous. + + * avrprog.c: + Add ability to specify the state of the power and reset pins on + program exit. Default to leaving the pins in the state they were when + we found them. + + Contributed by: Joerg Wunsch + +2001-01-18 Brian S. Dean <bsd@bsdhome.com> + + * Makefile, avrprog.c: + Switch to using readline() for getting terminal input. I can't seem + to get the history capabilities working yet, but even so, it does + better handling of the prompt and strips newlines for us, so it's + still a win. + + Add a few new commands for terminal mode: help, sig, part, erase. + Display rudimentory help using the help command. + + Add some function prototypes. + + * Usage, avrprog.c: + Change -c (interactive command mode) to the more intuitive -t + (terminal mode). + + Make binary format the default for output. + + Update the parts table with corrections for old values and add some + new values. + +2001-01-15 Brian S. Dean <bsd@bsdhome.com> + + * avrprog.c: + Automatically verify on-chip data with what we just programmed. + + * avrprog.c, Makefile: + Prepare the Makefile for integration into the FreeBSD ports tree. + + Fix a few "may be used uninitialized" bugs found by -Wall. + +2001-01-14 Brian S. Dean <bsd@bsdhome.com> + + * avrprog.c: Free a buffer. + + * avrprog.c: + Use a smarter programming algorithm - read the existing data byte + first and only write the new one if it is different. + + Add -n option which is a test mode in which the chip is not actually + updated. This option does not affect writes in interactive mode. + + * avrprog.c: Add the "dump" and "write" interactive commands. + + * avrprog.c: + Correctly produce and handle "end of record" for intel hex files. + +2001-01-13 Brian S. Dean <bsd@bsdhome.com> + + * avrprog.c: + Re-enable writing to the chip. I should probably should make this a + command-line selectable option so that I don't keep forgetting and + committing it with it disabled. + + * avrprog.c: + Add a newline before exiting due to command line errors. Perform a + bit more option compatibility testing between -c, -i, and -o. + + * avrprog.c: Add input file format auto-detection support. + + * Usage, avrprog.c: Say what the defaults are. + + * avrprog-programmer.jpg, Usage, avrprog-schematic.jpg: New files. + + * avrprog.c: Correct usage text. + + * avrprog.c: + Parameterize a few additional items per chip. Print out all per-chip + parameters on startup. Use the per-chip parameters in the code + instead of hard-coded values for the 2313. + + * avrprog.c: Fix filename assignment error. + + Clean up debugging code a little, utilize fileio() instead of making + direct calls to b2ihex(). + + * avrprog.c: A lot of general code cleanup. + + Re-work command line options to be more intuitive. + + Support Intel Hex input and output file formats. Provide hooks to + support Motorola S-Record as well. + + Add a few more part-specific parameters to the avrpart structure. + + Only write the flash or eeprom if the data to be written is not 0xff. + +2000-12-31 Brian S. Dean <bsd@bsdhome.com> + + * avrprog.c: Update a comment. + + * avrprog.c: + Provide the ability to tie additionally tie pins 6-9 of the parallel + port to Vcc in order to supply more current. + + Fix a typo on the size of the S1200's Flash. + + Bring RESET low when programming is completed. + + * avrprog.c: + Correct pin connection comments. Elaborate a bit on Vcc connection. + + * avrprog.c: + Update after receiving some good feedback from Joerg Wunsch. We + should now be able to program AT90S1200's. + +2000-12-30 Brian S. Dean <bsd@bsdhome.com> + + * avrprog.c: Don't limit eeprom addresses. + +2000-12-20 Brian S. Dean <bsd@bsdhome.com> + + * Makefile, avrprog.c: + Add support for the 8515. Make the addition for other devices easier. + +2000-08-27 Brian S. Dean <bsd@bsdhome.com> + + * avrprog.c: + Clear all bits except AVR_RESET when finished reading or programming + the Atmel device. + +2000-08-07 Brian S. Dean <bsd@bsdhome.com> + + * avrprog.c: update announcement message + + * avrprog.c: Update announcement message. + + * avrprog.c: Return the correct return code from 'main()'. + + * avrprog.c: + Add ppi_pulse() function and fix ppi_toggle() to actully toggle + instead of pulse. + + Make all abnormal returns after the parallel port has been opened go + through a single exit point at the bottom of 'main()'. + +2000-08-06 Brian S. Dean <bsd@bsdhome.com> + + * Makefile, avrprog.c: Makefile: add --pedantic compiler option + + avrprog.c: + + Add lots of comments, move getop() variable declarations to + the top of the program. + + Add a typedef name to the AVR memory type and use it for + function declarations. + + Add a usleep() delay in the sense loop to avoid becoming a cpu + hog. + + Print out a version string so that folks know what version of + the software they are running. + + Be sure and close the parallel device and the i/o file when + terminating abnormally. + + * avrprog.c: Print out version information when invoked. + + * Makefile, avrprog.c: Makefile: Add an install target. + + avrprog.c: + + Add license. + + Document the header a bit better. + + Add capability to read out and display the device signature bytes. + + Add capability to power the device from the parallel port. + + Eliminate debug print facility. + + Provide 'avr_cmd()' function. + + When memory locations don't program, generate a newline so that the + information is not overwritten and lost. + + Don't print out the message about needing to specify a file if the + user is not requesting an operation that requires the file. + +2000-08-05 Brian S.
