Optiboot bigboot ATmega2560 issue #1898

Closed mcuee closed 3 weeks ago

mcuee commented 3 weeks ago

So this is not a regression.

After the test, the bootloader does not seem to function.

Possible candidate serial ports are:
  -P COM3
  -P COM4 or -P ch340
Note that above ports might not be connected to a target board or an AVR programmer.
Also note there may be other direct serial ports not listed above.

Avrdude done.  Thank you.

Debugging the issue by reflashing the bootloader. So you can see the first command works. But then after that the bootloader communication will be lost.

@MCUdude Just wondering if you can reproduce the issue on your side or not. Thanks.

@stefanrueger Not so sure if this is a Optiboot bootloader limitation or not.

mcuee commented 3 weeks ago

Bootloader dump to see if it is corrupted or not.

The issue is with the flash related command.

After the flash related test item, the bootloader will be gone.

Try adding the -D flag

Probably the bootloader can not handle hex file with holes for Flash.

Looks like it. test-avrdude is designed to test this with difficult files. If only there was a better bootloader that people could use!

Okay, I will close this issue.

No worries.

@MCUdude has switched MegaCore to use urboot. The tests for Wiring Bootloader and Optiboot Bootloader for ATmega2560 are just for testing purpose to see if there are regressions.And there are no regressions. So we are good.

mcuee commented 3 weeks ago

We also have the recommended bootloader section in Wiki FAQ. https://github.com/avrdudes/avrdude/wiki/FAQ#i-have-got-the-programmer-working-now-i-want-to-try-using-bootloader-which-bootloader-should-i-use

We recommend urboot for classic AVR chips. For xmega, you may want to try xboot (AVR109 based) For UPDI parts, you may want to try optiboot_x and optibootdx. If you use USB AVRs, you may want to try Caterina (AVR109 based) or FLIP1/FLIP2 (Atmel extension to USB DFU).
