![]() ![]() Uno / 16Mhz full swing/ CS = pin4 / BOD = 2.7V / Proc. I have built a couple of custom designed 328p boards that I flashed with avr_boot using the setup of:ģ28p / Mod. Hello everybody! I hope that someone is still alerted by this addition to this topic. I cannot for the life of me see what I’m doing wrong this is driving me nuts.Īpplication runs, SD card works, and CS has been setup for Pin10 so I’m sure it’s not a hardware problem. I am a little confused because bitburner shows that 0xDA is 2048 bootloader size? 4096 is a different setting? I did change the fuse to 4096 and wrote the fuse setting direct using bit burner, but the bootloader still does not appear to work. When I burn the bootloader (avr_boot) I don’t get much information showing in the ide output window as you can see in the txt file attached, where as if I burn bootloader using the standard Mightycore Library (that dose not contain the sd booting code), after selecting and downloading avr_boot, I used bit burner to just read verify the fuse settings that are currently set, as you state show me 0xDA, so if bit burner is reading the chip that must be what is set surely? Using the avr_boot, I installed the package but it’s board pinout (avr_developer) did not work with my 1284p chip, I followed instructions and installed the Mightycore Device library, this gave me the option when I select the avr_boot to select Mightycore1284p pinout this seemed to solve the pinout problem and my application runs.but the bootloader does not loads the BIN file from the SD card, as it is supposed to. ![]() I apologize in advance maybe I’m a little slow here and confusing things, so starting at the beginning, I uploaded the two txt files to show the difference of information I get in the IDE when I burn bootloader, between using the avr_boot and the Mightcore1284p device library’s that I have installed. ![]() home/jenkins/workspace/arduino-builder-all-cross/src//arduino-builder/main.go:329 0xf78Ĭ:\Program Files (x86)\Arduino\arduino-builder returned 2 home/jenkins/workspace/arduino-builder-all-cross/src//builder/builder.go:227 0x35 home/jenkins/workspace/arduino-builder-all-cross/src//builder/builder.go:180 0xdcĪ/builder.RunParseHardwareAndDumpBuildProperties(0x120ce000, 0x0, 0x0) home/jenkins/workspace/arduino-builder-all-cross/src//builder/builder.go:191 0xe2Ī/builder.(*ParseHardwareAndDumpBuildProperties).Run(0x12089dec, 0x120ce000, 0x0, 0x0) home/jenkins/workspace/arduino-builder-all-cross/src//builder/setup_build_properties.go:84 0xfa7Ī/builder.(*ContainerSetupHardwareToolsLibsSketchAndProps).Run(0圆14ef0, 0x120ce000, 0x0, 0x0) Panic: runtime error: invalid memory address or nil pointer dereference Here is a copy of the error if i select standard Mighty1284P ![]() am i doing something wrong or is there another library to use? i tried downloading the Mighty 1284P standard as in your option selection, i just get a boards.txt error. However the hex file does not load, it just boots up as before with program not operating as it should, when i reload Mighty Core (standard pin), my project runs fine. Using avr_boot, I created BIN file as instructed and tried to load it, i moved my SD card CS to pin 10 (as i thought you should not use pin 4 on the 1284P the SS pin as a CS) I have been working on a project and would like to be able to flas … h my 1284P from SD card for updates, I have loaded your avr_boot, firstly i am unable to select standard pinout as it will not compile, so i left it set as, this must be different from standard as it my program although runs and loads does not run as it should (i was using the mightycore bootloader before), if i reload that, the code runs fine. ![]()
