From a0d00b4d86cfbd5cb508eda69997175fab39e725 Mon Sep 17 00:00:00 2001 From: WestfW Date: Mon, 13 Jun 2011 19:07:07 -0700 Subject: http://code.google.com/p/arduino/issues/detail?id=368 Optiboot does not support ArduinoasISP programmer. When avrdude runs and talks to an arduino running ArduinoISP, it needs the optiboot (entered due to auto-reset) to abort and start the ArduinoISP "application" when it sees communications at the wrong serial speed. Unfortunately, optiboot treats all unrecognized command characters as "no-ops" and responds/loops for more commands, leading to a nice loop that never gets to the sketch. This patch causes characters received with Framing errors (the most likely error for speed mis-matches) to NOT reset the watchdog timer (normally done in getch()), which will cause the application to start if it continues for "a while." (tested. Works! Running ArduinoISP at speeds as high as 57600 still causes the bootloader to start the sketch (although it fails later on for other reasons.)) --- bootloaders/optiboot/optiboot_luminet.lst | 153 ++++++++++++++---------------- 1 file changed, 73 insertions(+), 80 deletions(-) (limited to 'bootloaders/optiboot/optiboot_luminet.lst') diff --git a/bootloaders/optiboot/optiboot_luminet.lst b/bootloaders/optiboot/optiboot_luminet.lst index 447349d..e40e0ef 100644 --- a/bootloaders/optiboot/optiboot_luminet.lst +++ b/bootloaders/optiboot/optiboot_luminet.lst @@ -3,27 +3,27 @@ optiboot_luminet.elf: file format elf32-avr Sections: Idx Name Size VMA LMA File off Algn - 0 .text 00000244 00001d00 00001d00 00000054 2**1 + 0 .text 00000242 00001d00 00001d00 00000054 2**1 CONTENTS, ALLOC, LOAD, READONLY, CODE - 1 .version 00000002 00001efe 00001efe 00000298 2**0 + 1 .version 00000002 00001efe 00001efe 00000296 2**0 CONTENTS, READONLY - 2 .debug_aranges 00000028 00000000 00000000 0000029a 2**0 + 2 .debug_aranges 00000028 00000000 00000000 00000298 2**0 CONTENTS, READONLY, DEBUGGING - 3 .debug_pubnames 0000006d 00000000 00000000 000002c2 2**0 + 3 .debug_pubnames 0000006d 00000000 00000000 000002c0 2**0 CONTENTS, READONLY, DEBUGGING - 4 .debug_info 000002b1 00000000 00000000 0000032f 2**0 + 4 .debug_info 000002a2 00000000 00000000 0000032d 2**0 CONTENTS, READONLY, DEBUGGING - 5 .debug_abbrev 00000188 00000000 00000000 000005e0 2**0 + 5 .debug_abbrev 0000016f 00000000 00000000 000005cf 2**0 CONTENTS, READONLY, DEBUGGING - 6 .debug_line 000004a7 00000000 00000000 00000768 2**0 + 6 .debug_line 0000049d 00000000 00000000 0000073e 2**0 CONTENTS, READONLY, DEBUGGING - 7 .debug_frame 00000090 00000000 00000000 00000c10 2**2 + 7 .debug_frame 00000090 00000000 00000000 00000bdc 2**2 CONTENTS, READONLY, DEBUGGING - 8 .debug_str 00000158 00000000 00000000 00000ca0 2**0 + 8 .debug_str 00000158 00000000 00000000 00000c6c 2**0 CONTENTS, READONLY, DEBUGGING - 9 .debug_loc 00000268 00000000 00000000 00000df8 2**0 + 9 .debug_loc 00000268 00000000 00000000 00000dc4 2**0 CONTENTS, READONLY, DEBUGGING - 10 .debug_ranges 00000080 00000000 00000000 00001060 2**0 + 10 .debug_ranges 00000080 00000000 00000000 0000102c 2**0 CONTENTS, READONLY, DEBUGGING Disassembly of section .text: @@ -47,7 +47,7 @@ int main(void) { 1d04: 14 be out 0x34, r1 ;
