Everything works for me, and no further comments from the
submitter for 9 months.

Thanks for supplying the files.

I tried all combinations of the following:

. version 5.11.1 (latest release), with your hex file
. SVN version (r1125), with your hex file
. SVN version (r1125), with your ELF file (SVN version can
program ELF files directly, including sparse files)

with

. STK600
. STK500 (using V2 firmware)
. AVRISPmkII

All work as intended, i. e. the sparse files are being programmed
correctly. Consequently, the bug must be in the Arduino programmer/
bootloader, somehow. Presumably, it confuses the way the "load
address" command is implemented, in particular the use of bit 31 as an
indication to use extended (24-bit) addressing.

However, the log file you submitted does not match the ELF/hex files
you uploaded later. The load address commands in your log are:

[06] . [80] . [00] . [00] . [00]
[06] . [80] . [00] . [80] . [00]
[06] . [80] . [00] . [f6] . [80]

If I flash your hex file, I get:

[06] . [80] . [00] . [00] . [00]
[06] . [80] . [00] . [80] . [00]
[06] . [80] . [01] . [00] . [00]
[06] . [80] . [01] H [48] . [00]

Note that the addresses in the "load address" command are 16-bit word
addresses (when operating on flash), so the respective byte address
blocks are 0, 0x10000, 0x1ed00 for your log file, and 0, 0x10000,
0x20000, 0x29000 for your hex file.

Files Attached (within debug_files.tar.gz):

SabatoKeypad.cpp.elf : ELF file of my application
SabatoKeypad.cpp.hex : Intel HEX generated from the ELF
SabatoKeypad.cpp.bin : RAW binary generated from the ELF
short_log.txt : Log (3 "-v"s) of write/verify (HEX vs BIN)
long_log.txt : Log (5 "-v"s) of write/verify (HEX vs BIN)
failed.bin : Binary dump of flash after failure

The "failed.bin" was created by first filling bottom 240KB of Flash w
ith 0x55, then programming from Intel HEX, then reading back the Flash.
Maybe it will help isolate WHERE the bad data was written. (You can
also see the bootloader in there, in case there is some relevant bug
that was fixed after Sept 2010).

Let me know if there's anything else I can do to help.

Would you be willing to also supply the hex file in question?

Sat 24 Nov 2012 01:32:55 AM UTC, original submission:

Avrdude 5.11, as included in Arduino 1.0.1. Using stk500v2 protocol and Arduino bootloader-based programming.

I thought I'd submitted this already, but maybe it never went through.

I had a project which partially utilizes bottom 64KB, then packs some binary data beginning at 128KB & 192KB. The Flash was incorrectly programmed starting at 0x10000. I tried both Intel and Motorola formats, same thing. I then generated a 256KB binary file, and that one programmed correctly. Hence I suspect it's an issue jumping the programming forward over a 64KB boundary.

Have attached a verbose log of the programming which failed.
