* avrdude - A Downloader/Uploader for AVR device programmers
Mega-commit to bring in both, the STK500v2 support from Erik Walthinsen, as well as JTAG ICE mkII support (by me). Erik's submission has been cleaned up a little bit, mostly to add his name and the current year to the copyright of the new file, remove trailing white space before importing the files, and fix the minor syntax errors in his avrdude.conf.in additions (missing semicolons). The JTAG ICE mkII support should be considered alpha to beta quality at this point. Few things are still to be done, like defering the hfuse (OCDEN) tweaks until they are really required. Also, for reasons not yet known, the target MCU doesn't start to run after signing off from the ICE, it needs a power-cycle first (at least on my STK500). Note that for the JTAG ICE, I did change a few things in the internal API. Notably I made the serial receive timeout configurable by the backends via an exported variable (done in both the Posix and the Win32 implementation), and I made the serial_recv() function return a -1 instead of bailing out with exit(1) upon encountering a receive timeout (currently only done in the Posix implementation). Both measures together allow me to receive a datastreem from the ICE at 115 kbps on a somewhat lossy PCI multi-UART card that occasionally drops a character. The JTAG ICE mkII protocol has enough of safety layers to allow recovering from these events, but the previous code wasn't prepared for any kind of recovery. The Win32 change for this still has to be done, and the traditional drivers need to be converted to exit(1) upon encountering a timeout (as they're now getting a -1 returned they didn't see before in that case). git-svn-id: svn://svn.savannah.nongnu.org/avrdude/trunk/avrdude@451 81a1dc3b-b13d-400b-aceb-764788c761c2

Enable stdin verification and display correct number of bytes written/verified Counting the number of bytes written to a memory and/or verified is not trivial owing to potential holes in the input file and to potential trailing 0xff bytes in flash memory that are not written per default (but see -A). The new function memstats(), which is best called just after an input file has been read into mem->buf/mem->tags, computes the right number of bytes written and allows easy computation of the number of bytes verified. This commit also changes the strategy for the default verification after writing to a chip memory, so that the input file only needs reading once thus enabling successful verification of stdin input files. Other, minor changes: - Improving the grammar of AVRDUDE output, eg, 1 byte written instead of 1 bytes written - Better description of the input file structure in terms of its sections, the interval it spans, the number of pages, the number of padding bytes in pages, and the number of actually cut off trailing 0xff bytes for flash - Printing <stdin> or <stdout> instead of - in the -U routines - Option -V no longer needs to be specified before option -U in order to work As an aside this commit also provides useful helper functions for printing plural(), inname(), outname() and interval() all of which return strings fit for printing. $ avrdude -qp ATmega2560 -c usbtiny -U blink-mega2560+lext-test.hex avrdude: AVR device initialized and ready to accept instructions avrdude: Device signature = 0x1e9801 (probably m2560) avrdude: NOTE: "flash" memory has been specified, an erase cycle will be performed To disable this feature, specify the -D option. avrdude: erasing chip avrdude: input file blink-mega2560+lext-test.hex auto detected as Intel Hex avrdude: reading input file blink-mega2560+lext-test.hex for flash with 1346 bytes in 4 sections within [0, 0x3106d] using 7 pages and 446 pad bytes avrdude: writing 1346 bytes flash ... avrdude: 1346 bytes of flash written avrdude: verifying flash memory against blink-mega2560+lext-test.hex avrdude: 1346 bytes of flash verified avrdude done.

The JTAG ICE mkII support should be considered alpha to beta quality at this point. Few things are still to be done, like defering the hfuse (OCDEN) tweaks until they are really required. Also, for reasons not yet known, the target MCU doesn't start to run after signing off from the ICE, it needs a power-cycle first (at least on my STK500). Note that for the JTAG ICE, I did change a few things in the internal API. Notably I made the serial receive timeout configurable by the backends via an exported variable (done in both the Posix and the Win32 implementation), and I made the serial_recv() function return a -1 instead of bailing out with exit(1) upon encountering a receive timeout (currently only done in the Posix implementation). Both measures together allow me to receive a datastreem from the ICE at 115 kbps on a somewhat lossy PCI multi-UART card that occasionally drops a character. The JTAG ICE mkII protocol has enough of safety layers to allow recovering from these events, but the previous code wasn't prepared for any kind of recovery. The Win32 change for this still has to be done, and the traditional drivers need to be converted to exit(1) upon encountering a timeout (as they're now getting a -1 returned they didn't see before in that case). git-svn-id: svn://svn.savannah.nongnu.org/avrdude/trunk/avrdude@451 81a1dc3b-b13d-400b-aceb-764788c761c2

Enable stdin verification and display correct number of bytes written/verified Counting the number of bytes written to a memory and/or verified is not trivial owing to potential holes in the input file and to potential trailing 0xff bytes in flash memory that are not written per default (but see -A). The new function memstats(), which is best called just after an input file has been read into mem->buf/mem->tags, computes the right number of bytes written and allows easy computation of the number of bytes verified. This commit also changes the strategy for the default verification after writing to a chip memory, so that the input file only needs reading once thus enabling successful verification of stdin input files. Other, minor changes: - Improving the grammar of AVRDUDE output, eg, 1 byte written instead of 1 bytes written - Better description of the input file structure in terms of its sections, the interval it spans, the number of pages, the number of padding bytes in pages, and the number of actually cut off trailing 0xff bytes for flash - Printing <stdin> or <stdout> instead of - in the -U routines - Option -V no longer needs to be specified before option -U in order to work As an aside this commit also provides useful helper functions for printing plural(), inname(), outname() and interval() all of which return strings fit for printing. $ avrdude -qp ATmega2560 -c usbtiny -U blink-mega2560+lext-test.hex avrdude: AVR device initialized and ready to accept instructions avrdude: Device signature = 0x1e9801 (probably m2560) avrdude: NOTE: "flash" memory has been specified, an erase cycle will be performed To disable this feature, specify the -D option. avrdude: erasing chip avrdude: input file blink-mega2560+lext-test.hex auto detected as Intel Hex avrdude: reading input file blink-mega2560+lext-test.hex for flash with 1346 bytes in 4 sections within [0, 0x3106d] using 7 pages and 446 pad bytes avrdude: writing 1346 bytes flash ... avrdude: 1346 bytes of flash written avrdude: verifying flash memory against blink-mega2560+lext-test.hex avrdude: 1346 bytes of flash verified avrdude done.

Mega-commit to bring in both, the STK500v2 support from Erik Walthinsen, as well as JTAG ICE mkII support (by me). Erik's submission has been cleaned up a little bit, mostly to add his name and the current year to the copyright of the new file, remove trailing white space before importing the files, and fix the minor syntax errors in his avrdude.conf.in additions (missing semicolons). The JTAG ICE mkII support should be considered alpha to beta quality at this point. Few things are still to be done, like defering the hfuse (OCDEN) tweaks until they are really required. Also, for reasons not yet known, the target MCU doesn't start to run after signing off from the ICE, it needs a power-cycle first (at least on my STK500). Note that for the JTAG ICE, I did change a few things in the internal API. Notably I made the serial receive timeout configurable by the backends via an exported variable (done in both the Posix and the Win32 implementation), and I made the serial_recv() function return a -1 instead of bailing out with exit(1) upon encountering a receive timeout (currently only done in the Posix implementation). Both measures together allow me to receive a datastreem from the ICE at 115 kbps on a somewhat lossy PCI multi-UART card that occasionally drops a character. The JTAG ICE mkII protocol has enough of safety layers to allow recovering from these events, but the previous code wasn't prepared for any kind of recovery. The Win32 change for this still has to be done, and the traditional drivers need to be converted to exit(1) upon encountering a timeout (as they're now getting a -1 returned they didn't see before in that case). git-svn-id: svn://svn.savannah.nongnu.org/avrdude/trunk/avrdude@451 81a1dc3b-b13d-400b-aceb-764788c761c2

Both measures together allow me to receive a datastreem from the ICE at 115 kbps on a somewhat lossy PCI multi-UART card that occasionally drops a character. The JTAG ICE mkII protocol has enough of safety layers to allow recovering from these events, but the previous code wasn't prepared for any kind of recovery. The Win32 change for this still has to be done, and the traditional drivers need to be converted to exit(1) upon encountering a timeout (as they're now getting a -1 returned they didn't see before in that case). git-svn-id: svn://svn.savannah.nongnu.org/avrdude/trunk/avrdude@451 81a1dc3b-b13d-400b-aceb-764788c761c2
