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).

file. Finally, a ``terminal'' mode is available that allows one to

from within terminal mode as well.

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).

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

programmer's entry of the configuration file.

|
|
|
|
.It Fl B Ar bitclock
|

|
Specify the bit clock period for the JTAG interface (JTAG ICE only).
|
|
|
|
|
The value is a floating-point number in microseconds.
|
|
|
|
|
The default value of the JTAG ICE results in about 1 microsecond bit
|
|
|
|
|
clock period, suitable for target MCUs running at 4 MHz clock and
|
|
|
|
|
above.
|
|
|
|
|
Unlike certain parameters in the STK500, the JTAG ICE resets all its
|
|
|
|
|
parameters to default values when the programming software signs
|
|
|
|
|
off from the ICE, so for MCUs running at lower clock speeds, this
|
|
|
|
|
parameter must be specified on the command-line.

submit a patch back to the author so that it can be incorporated for

2003-03-10 21:51:55 +00:00

|
|
|
|

will perform a chip erase before starting any of the programming

|
|

operations, since it generally is a mistake to program the flash
|
|
|

without performing an erase first. This option disables that.

.It Fl e

Causes a chip erase to be executed. This will reset the contents of the

|
|
|
|
flash ROM and EEPROM to the value
|
|
|
|
|
.Ql 0xff ,
|
|
|
|
|
and is basically a prerequisite command before the flash ROM can be
|
|
|
|
|
reprogrammed again. The only exception would be if the new

contents would exclusively cause bits to be programmed from the value

Note that in order to reprogram EERPOM cells, no explicit prior chip

erase is required since the MCU provides an auto-erase cycle in that

|
|
|
|
case before programming the cell.

indicate what memory type to operate on, what operation to perform is
(read, write, or verify), the filename to read from, write to, or
verify against, and an optional file format field. Multple -U options
can be specified to operate on more than one memory at a time with a
single invocation. For example, to update both the flash and the

2002-10-13 04:22:59 +00:00

to use the last four bytes of the connected parts' EEPROM memory to
|
2002-08-01 01:00:03 +00:00
|
|
|
track the number of times the device has been erased. When this

|

option is used and the
|
|
|
|
|
.Fl e
|
|
|
|
|
flag is specified to generate a chip erase, the previous counter will
|
|
|
|
|
be saved before the chip erase, it is then incremented, and written
|
|
|
|
|
back after the erase cycle completes. Presumably, the device would
|
|
|
|
|
only be erased just before being programmed, and thus, this can be
|
2002-08-01 02:06:48 +00:00
|
|
|
utilized to give an indication of how many erase-rewrite cycles the
|
2002-08-01 01:00:03 +00:00
|
|
|
part has undergone. Since the FLASH memory can only endure a finite
|
|
|
|
|
number of erase-rewrite cycles, one can use this option to track when
|
|
|
|
|
a part is nearing the limit. The typical limit for Atmel AVR FLASH is
|
2002-10-13 04:22:59 +00:00
|
|
|
1000 cycles. Of course, if the application needs the last four bytes
|
2002-08-01 01:00:03 +00:00

|
of EEPROM memory, this option should not be used.

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).
