Bootloader Fail Arduino IDE

[dunk8888]

Hi does 2boots work with arduino ide? it tryes to work the rx led flashes 3 times when i try to upload sketch to my arduino uno,ive tryed a few ide new and old,i thought it was supposed to work with arduino as well as having the mmc sd card upload option.stk500 not in sync is the error it gives.
Thanks

2boots-arduino-atmega328p-16000000L-PD4.hex is the hex ive loaded via isp ime using arduino uno,ive tryed two uno with same results.is boot flash size 2048 and is boot reset vector enabled? ive tred both with same results.

Also will the sd card boot option work with attiny? i know serial wont work?

Hello dunk8888,

Thanks for giving 2boots a try! Regarding your questions:

• Yes, the stk500 protocol used by Arduino IDE (avrdude) should be supported.
• Yes, fuses for boot flash size 2048 and boot reset vector enabled is correct for atmega328p.
• No, ATtiny are not yet supported by 2boots. Which exact part would you like to use?

Also: Can you send my the exact error messages when the upload from Arduino IDE fails?

Thanks a lot and best regards,
Thomas

Also, please double check that your fuses are set correctly, especially:

• BOOTRST = 0 (boot reset vector enabled, this calls the bootloader on power up)
• BOOTSZ = 01 (bootloader size = 1024 words, or 2048 bytes)

I have the same issue as dunk8888. Not working in arduino IDE.

Not tested if SD boot load.
