bug #34027: avrdude AT90S1200 Problem (part 1 - bitbang
programmers) * config_gram.y: Introduce new keyword "is_at90s1200". * lexer.l: (Ditto.) * avrdude.conf.in: Applew new keyword to the AT90S1200 device. * avrpart.h: Introduce new flag AVRPART_IS_AT90S1200, reflecting the is_at90s1200 configuration keyword. * bitbang.c (bitbang_initialize): Replace existing test for AT90S1200 by AVRPART_IS_AT90S1200 * avr.c (avr_write_byte_default): Avoid the pre-write reading for the AT90S1200, as this appears to sometimes corrupt the high byte by pre-programming the low byte just written into it. git-svn-id: svn://svn.savannah.nongnu.org/avrdude/trunk/avrdude@1002 81a1dc3b-b13d-400b-aceb-764788c761c2

bug #34027: avrdude AT90S1200 Problem (part 1 - bitbang
|
||||||
|
programmers)
|
||||||
|
* config_gram.y: Introduce new keyword "is_at90s1200".
|
||||||
|
* lexer.l: (Ditto.)
|
||||||
|
* avrdude.conf.in: Applew new keyword to the AT90S1200 device.
|
||||||
|
* avrpart.h: Introduce new flag AVRPART_IS_AT90S1200, reflecting
|
||||||
|
the is_at90s1200 configuration keyword.
|
||||||
|
* bitbang.c (bitbang_initialize): Replace existing test for
|
||||||
|
AT90S1200 by AVRPART_IS_AT90S1200
|
||||||
|
* avr.c (avr_write_byte_default): Avoid the pre-write reading for
|
||||||
|
the AT90S1200, as this appears to sometimes corrupt the high byte
|
||||||
|
by pre-programming the low byte just written into it.
