• 963abd0282 Automatically change section start address of app for BIGBOOT. add labels for clearer "size" output; run size on the .hex file as well, to show just the bootloader size. WestfW 2021-06-28 00:34:25 -07:00
• bcc71438fe Changes to allow pins_rs485.h to be used with both mega0/xTiny chips as well as older AVRs (PORTx vs VPORTx stuff.) Also adjust the build info included in the BIGBOOT image. WestfW 2021-06-27 19:20:01 -07:00
• 084c69c6b8 More of the great re-formatting and de-tabification. Mostly on optiboot_x.c, this time. WestfW 2021-06-27 00:36:05 -07:00

• 4782909e30 Add NO_START_APP_ON_POR and START_APP_ON_EXTR support from ATTinyCore. (with makefile aliases "BOOT_ON_POR" and "APP_ON_EXTR") (binaries for ATmega328 with these options come out identical to ATTinyCore.) WestfW 2021-05-14 18:14:06 -07:00
• db59a84013 Clean up some of the uglier CPU dependencies to make the code easier to read. WestfW 2021-05-03 23:16:22 -07:00
• 64bda3d518 Bring the buildable attiny targets up-to-date WRT Spence Konde's ATTinyCore. This fixes the makefiles, expands makeall.tiny.sh, and a small warning generated by optiboot.c. WestfW 2021-05-02 00:55:53 -07:00

• 6aa5871762 oops. Finish the test_nmvctrl filename changes. add symbolic values for memory regions (sigrow fuses userrow eeprom) and nvmctrl->ctla command ("copy", write, wp, erase, ep, erwp, pbc, cher, eeer) WestfW 2020-09-30 23:44:14 -07:00
• 4c564c2b17 rename test_reset --> demo_reset WestfW 2020-09-30 01:36:43 -07:00
• 2f3cf2887e rename some of the test_* examples to demo_* to reflect that they're closer to actual examples, as opposed to some of the other test_* code, which is more like optiboot devlopment testing. add a readme file to the examples directory. WestfW 2020-09-30 01:29:32 -07:00

• aa46aa0db8 Bump version for fixed do_nvmctrl WestfW 2020-09-28 03:31:05 -07:00
• eb4416a5f0 Add optiboot_x nvmctrl support to optiboot.h minor fixes in test_dospm itself. test_dospm (which uses only the "high level" calls to read and write pages) now works the same (I think) on both traditional AVR and new mega0/xTiny chips. WestfW 2020-09-28 02:57:14 -07:00
• 7975070bdc Fix do_nvmctrl() (probably) add a test_nvmctrl.ino sketch in examples that allows one to poke at it. (the test sketch needs additional work; most of optiboo_x.h is commented out, and it should be merged with optiboot.x) WestfW 2020-09-27 01:30:17 -07:00

  Fix spelling mistakes & grammar Peter Smythe 2020-08-16 08:03:23 +02:00
• 6f98751c6d Change the compile option symbols to be true/false instead of sometimes defined/undefined, so that specifying "LED_START_ON=0" doesn't actually cause the same behvaior as "LED_START_ON=1" WestfW 2020-06-18 00:48:08 -07:00

  Merge pull request #282 from enekochan/patch-1 Bill Westfield 2020-05-29 02:31:00 -07:00
• 27f6adf44a Fix "make help", at least on unixy systems. Remove the UARTTX option, which is only relevant for mega0 targets. WestfW 2020-05-29 02:17:56 -07:00
• 0b9a50d4e6 Add TIMEOUT option to Makefile. Implement this in optiboot.c Fix comments so that TIMEOUT is in seconds (compatible with optiboot_x) Check for illegal timeouts on older chips (4s and 8s are impossible on ATmega8) by checking whether the extra bit is defined in the ioxxx.h file.

• 1810af8050 Better error handling for bad UARTTX settings. Update copyright and license pointer. WestfW 2020-01-09 02:06:29 -08:00
• eac5d189a4 Additional make targets for generic ATmega% and ATtiny%. Also "make version" to report various tool and source versions. Omit the application section from the final binary/hex file. (and explain why!) WestfW 2020-01-09 02:01:52 -08:00

• 1b8e4bce09 Always write PMUX register, even if the pin selection is the default. This may solve some problems if a new bootloader is run without a reset, somehow. WestfW 2019-10-13 00:13:45 -07:00
• 35ba394479 More support for mega-0 chips WestfW 2019-10-01 02:51:19 -07:00
• a21d20fd63 Add some mention of optiboot_x WestfW 2019-10-01 02:49:14 -07:00
• 9fde01e634 Fix LED_INVERT option. Add ATtiny817 to pin_defs_x.h WestfW 2019-09-23 01:55:49 -07:00
• 142c9f7c5f Dynamically derive the chip clock rate, so we no longer need AVR_FREQ, or separate binaries for different clockrates. WestfW 2019-09-20 19:43:18 -07:00
• d4c67cdd36 Mostly, add help text to Makefile.mega0 WestfW 2019-09-16 02:13:52 -07:00
• c3344d7dfc Makefile now usable. For example "make -f Makefile.mega0 drazzy3217" Add LED_INVERT option to makefile option parser. Clean up RSTPIN for chips with only two values. Shave off a few bytes by writing PMUX instead of ORing, and using the default clock speed (20MHz/6) instead of turning off the divider. (not that we need to save space yet.) Implement something for the "do_spm" function. This just writes "cmd" to NVMCTREL.CTRLA; I'm not sure whether an application can write to the page buffer to make that sufficient. Needs testing. WestfW 2019-09-15 02:22:45 -07:00
• 74efdb6699 Mega0 Makefile in good enough shape for initial commit. "make optiboot_<mcuname>.hex <options>" should build a .hex file for any of the "xmgea3" chips (mega0, tiny0, tiny1) WestfW 2019-09-13 18:26:38 -07:00
• 775cb1f6cd Implement TIMEOUT option. ATtiny412 working. add RSTPIN option to control the (internal) FUSE values. More source code "prettyfication" WestfW 2019-09-11 02:21:14 -07:00
• ad0f55574a Two important discoveries: 1) Changing the watchdog period (inc turning it on) requires paying attention to synchonization between the WDT clock and system clock. 2) "jmp 512" doesn't work. I'm not sure exactly what happens, but it doesn't go where I expected. WestfW 2019-09-10 01:17:13 -07:00
• adafe79832 More 14/20 bit chip defintions. Mostly, struggling with IDEs :-( WestfW 2019-09-06 01:06:24 -07:00
• 51b9eec272 Fix embarassing copy/paste errors in pin defs for 8pin tiny. Try to add a dummy "application" for freshly programmed parts, that will keep running the bootloader instead of keep running the empty app. (Doesn't work, though. MPLAB won't program it!) Clean up some obsolete comments. WestfW 2019-09-05 02:17:40 -07:00
• 58a71b130f Modifications for ATtiny4x2, at least as far as compilation. Eliminate RTC-based LED flashing code in favor of busy loop, which is significantly shorter now that peripherals are not in range of quick IO instructions. Minor formatting changes while the code is young (notably spaces after the function name at the spot where they're actually defined, which makes them easier to search for. Ancient corporate coding style guideline...) WestfW 2019-09-04 01:21:27 -07:00
• bb9ae67aee Day of testing and minor edits. The RTC might be busy at startup. This seems to be working - code successfully uploaded, after I got all the fuses right. WestfW 2019-09-03 02:57:51 -07:00
• 1d763359a7 Debugging. WestfW 2019-09-02 03:03:17 -07:00
• 4c12f27e66 New version of optiboot for Mega0 and xTiny AVRs. Uses NVMCTRL, and of course all of the peripherals have changed. WestfW 2019-09-01 21:58:21 -07:00
• 5c67c2d688 Fix bug(s) in calculation of rjmp offset for virutal boot builds. See https://github.com/Optiboot/optiboot/issues/275 WestfW 2019-08-28 14:06:33 -07:00
• abbe828f81 oops. Last commit had a bug or two, and while every .hex file tha built matched the prvious verion, some of them didn't build at all. WestfW 2019-08-27 23:39:25 -07:00
• ba257540f8 restructure the Virtual Boot code so that it is easier to read. These are preprocesing and commenting changes, and do not cause any changes in the binaries (tested for all of the bootloaders generated by the makeall.* scripts.) WestfW 2019-08-27 19:17:59 -07:00
