Loading speed on AtmelICE

[celephicus]

Bloom works well, and has let me retire my Windows laptop as the only reason I had it was for Atmel Studio debugging. But I'm using the Mega328P on DebugWire, and the upload speed is very slow. Is there any way of speeding it up a bit?

Could you please enable debug logging and send me the log output of a debug session where you run the load command? This will give me an idea of what's going on. You may have to put the log output in a text file and attach to the comment as GitHub has some character length restrictions for comments.

To enable debug logging, just set debugLogging to true in the root node of your bloom.yaml:

debugLogging: true

environments:
...

Does Atmel Studio upload faster? To what extent?

Does your ELF contain EEPROM sections? IIRC, writing EEPROM is quite slow on debugWire targets, so that could be the problem.

What's the size of the program you're uploading?

Are you using any IDE like CLion? Is it restarting Bloom for every debug session? If so, it could be startup/shutdown times that are slowing things down. I raised this with Jetbrains a few weeks back.

BTW, the debug log output may contain binary segments of your EEPROM memory, and maybe other sections of your ELF.

If this is a problem (you don't want to expose certain segments of your program), I can walk you through truncating the appropriate log lines, if you wish.

Sorry to take so long, I've done some testing, removed the eeprom section which made little difference. My program is about20KB, quite modest. The bloom log is attached.
bloom.log
Sorry I haven't tried Atmel Studio yet, I can install it on another laptop if this is important, but it is significant effort.

The target was an 8MHz 328P.I can confirm that loading similar size programs to the same target running at 16MHz takes a few seconds, not over 30 secs.
